Who's Afraid of File Format Obsolescence?

Evaluating File Format Endangerment Levels and Factors for the Creation of a File Format Endangerment Index

Heather Ryan, University of Denver Library and Information Science

 

Much digital preservation research has been built on the assumption that file format obsolescence poses a great risk to the continued access of digital content. In an endeavor to address this risk, a number of researchers created lists of factors that could be used to assess risks associated with digital file formats. My research examines these assumptions about file format obsolescence and file format evaluation factors with the aim of creating a simplified file format endangerment index.

This study examines file format risk under the new lens of 'file format endangerment,' or the possibility that information stored in a particular file format will not be interpretable or renderable in human accessible means within a certain timeframe. Using the Delphi method in two separate studies, this exploratory research collected expert opinion on file format endangerment levels of 50 test file formats; and collected expert opinion on relevance of 28 factors as causal indicators of file format endangerment.

Experts expressed the belief that generally, digital information encoded in the rated file formats will be accessible for 20 years or more. This indicates that file format experts believe that there is not a great deal of short-term risk associated with encoding information in the rated file formats, though this does not preclude continued engagement with preservation activities for these and other file formats. Furthermore, the findings show that only three of the dozens of file format evaluation factors discussed in the literature exceeded an emergent threshold level as causal indicators of file format endangerment: 'Rendering Software Available,' 'Specifications Available,' and 'Community/3rd Party Support.'  Consequently, these factors are ideal candidates for use in a simple file format endangerment index that can be used to assess endangerment levels of any file format.

The findings of this study have implications for further exploration of file format endangerment in specific digital information creation domains. In particular, applying this model to file formats created by and used in the Earth and Space Science communities will both strengthen the model and will produce valuable insight into format-centric Earth and Space Science data creation and management practices. This insight can then be applied to risk assessment and subsequent actions to support continued access to datasets over time.

An Easy Bake Semantic Metadata Repository for Scientific Data

Mik Cox, Tyler Traver, Anne Wilson, Doug Lindholm, Laboratory for Atmospheric and Space Physics (LASP), Don Elsborg, CU Faculty Affairs

 

This presentation will discuss the use of open source tools and the tasks that remained to create a semantically enabled metadata repository.

The LASP Interactive Solar Irradiance Data Center, LISIRD, is a web site that serves the lab's solar irradiance and related data products to the public. LISIRD provides information about the data it offers as part of its web page content, embedded in static HTML. At the same time, other LASP web sites also provide the same information, such as sites pertaining to specific missions or education and outreach.  Keeping data set information updated and in sync across web sites is a problem. Nor is the information interoperable with emerging search and discovery tools.

To address this and other issues, we created a semantically enabled metadata repository that holds information about our data.  In conjunction, we prototyped a new implementation of LISIRD that dynamically renders page content, pulling metadata from the repository and including in the page current, vetted metadata from a single, definitive source. Other web pages can similarly pull this information if they choose.  Additionally we can now offer new semantic browse and search capabilities, such as search of data sets by type (currently spectral solar irradiance, total solar irradiance, and solar indices) or over a particular spectral range provided by the user.

We can also render the metadata in various formats understandable to other communities, such as SPASE for the heliophysics community and ISO for the international community. This will allow us to federate with sites that use those formats, allowing broader discovery of our data.

To date, metadata management at LASP has generally been done on a per project, ad hoc basis. We are building applications on top of the repository that provide CRUD (create, read, update, delete) capabilities for metadata records to metadata 'owners' and 'curators'. We expect this to help data managers to store and manage their metadata in a more rigorous fashion should they choose to use it.

We heavily leveraged existing open source tools to create the repository. In this talk we'll talk about using VIVO to create a semantic database, LaTiS to fetch data and metadata, and AngularJS to write dynamic, testable JavaScript.  We'll describe our experiences extending two existing ontologies to meet our space physics domain needs.

With these tools and some student time (though our students are exceptional) we are achieving significantly increased capabilities at a relatively low cost. We believe this tool combination could help projects with limited resources achieve similar capabilities to manage and provide access to metadata.

Earth System CoG and the Earth System Grid Federation: A Partnership for Improved Data Management and Project Coordination

Sylvia Murphy, Cecelia DeLuca, Allyn Treshansky, NOAA/CIRES, Luca Cinquini, JPL/NOAA

The Earth System CoG Collaboration Environment, led by a NOAA ESRL/CIRES team, is partnering with the DOE-led Earth System Grid Federation (ESGF) data archive to deliver a capability that will enable users to store, federate, and search scientific datasets, and manage and connect the projects that produced those datasets.  

ESGF is an international network of data nodes that is used to host climate data sets, including the model outputs from the Coupled Model Intercomparison Project (CMIP), which supported the Intergovernmental Panel on Climate Change (IPCC) assessment reports.  ESGF data nodes are federated, so that all data holdings are visible from any of the installation sites.  An ESGF data node is now installed at NOAA’s Earth System Research Laboratory (ESRL’s).  It currently hosts data from the Dynamical Core Model Intercomparison Project (DCMIP) and Twentieth Century Reanalysis data from ESRL’s Physical Sciences Division.

CoG is a collaboration environment and connective hub for networks of projects in the Earth Sciences.  It hosts software development projects, model intercomparison projects, and short university-level courses. It includes a configurable search to data on any ESGF node, metadata collection and display,  project-level wikis, and a host of other capabilities. There are 74 projects currently using the system.

CoG is partnering with the international Earth System Model Documentation (ES-DOC) project, funded by both NOAA and the EU’s Infrastructure for the European Network for Earth System Modeling (IS-ENES) project. ES-DOC is developing tools that capture, display, and compare Earth system model metadata. This information can be linked directly from a CoG project or attached to specific datasets in the ESGF node.

This presentation will provide an overview of both CoG and ESGF, demonstrate data discovery and download, and key CoG capabilities using relevant example projects.

Accessing Data Instead of Ordering Data: A New Normal

Michael Little, the Advanced Development Systems Engineer at the Atmospheric Science Data Center (ASDC)

Mike will describe how the new generation of research objectives will need to avoid staging data locally from multiple modeling and observational repositories.  Rather, new access methods will present a machine-to-machine interface which permits codes and software applications to retrieve small increments of data continuously as part of the processing.  The ASDC's Data Acess architecture will be described with a particular emphasis on iRODS as one of the most promising tools for remote access to data held in earth science data centers.

Deep Carbon Observatory - Data Science and Data Management Infrastructure Overview and Demonstration

Patrick West, Rensselaer Polytechnic Institute

The Deep Carbon Observatory (DCO) brings together hundreds of organizations and individuals from all around the world, spanning a great many scientific domains with a focus on Carbon. The DCO Data Science team is anticipating the generation of terabytes of information in the form of documents, scientific datasets from level 0 to data products and visualizations, information about events, people, and organizations, and more. So how do we keep track of all of this information, manage the information, and disseminate the information?

In order to organize all of this information and provide the research community the tools necessary to collaborate and do their research, the DCO Data Science team is putting together a suite of tools that will integrate all of these components in a seamless, distributed, heterogeneous environment. This presentation and demonstration will provide an overview of the work that we, the DCO Data Science team, are doing to provide such an environment.

Due to Patrick's schedule, we'll plan on starting at 4:15 instead of 4:00.

Improving Science with Open Formats and High-Level Languages: Python and HDF5

Andrew Collette, Laboratory for Atmospheric and Space Physics (LASP)

This talk explores how researchers can use the scalable, self-describing HDF5 data format together with the Python programming language to improve the analysis pipeline, easily archive and share large datasets, and improve confidence in scientific results.  The discussion will focus on real-world applications of HDF5 in experimental physics at two multimillion-dollar research facilities: the Large Plasma Device at UCLA, and the NASA-funded hypervelocity dust accelerator at CU Boulder.  This event coincides with the launch of a new O’Reilly book, Python and HDF5: Unlocking Scientific Data, complimentary copies of which will be available for attendees.

As scientific datasets grow from gigabytes to terabytes and beyond, the use of standard formats for data storage and communication becomes critical.  HDF5, the most recent version of the Hierarchical Data Format originally developed at the National Center for Supercomputing Applications (NCSA), has rapidly emerged as the mechanism of choice for storing and sharing large datasets.   At the same time, many researchers who routinely deal with large numerical datasets have been drawn to the Python by its ease of use and rapid development capabilities. 

Over the past several years, Python has emerged as a credible alternative to scientific analysis environments like IDL or MATLAB.  In addition to stable core packages for handling numerical arrays, analysis, and plotting, the Python ecosystem provides a huge selection of more specialized software, reducing the amount of work necessary to write scientific code while also increasing the quality of results.  Python’s excellent support for standard data formats allows scientists to interact seamlessly with colleagues using other platforms.

Regridding of data is a common problem faced by many scientific software developers.   If regridding is part of your world, this talk may be of interest to you.  Come join us at the Boulder Outlook Hotel for this month's talk:

There is more to conservative interpolation--- interpolating edge and face centered fields in the geo-sciences

Alexander Pletzer, Tech-X

Interpolation is one of the most widely used postprocessing tasks, according to a survey of Ultrascale Visualization Climate Data Analysis Tools (UV-CDAT) users. Most geo-postprocessing tools (UV-CDAT, NCL, Ferret, etc) support a choice of both bilinear and conservative regridding with conservative interpolation guaranteeing that the total amount of "stuff" (energy, water, etc) remains unchanged after regridding. The SCRIP and ESMF are examples of libraries implementing these interpolation methods.

We argue that the type of interpolation is dictated by the type of field and that cell centered fields require conservative interpolation whereas nodal fields require bilinear (or higher order) interpolation. Moreover, the wind velocity fields used by finite-volume atmospheric codes, which are neither cell-centered nor nodal but face-centered (Arakawa D staggering), require different interpolation formulas. Interpolation formulas of face-centered and edge-centered (Arakawa C) fields have been known as Whittney forms since 1957 and are widely used in electromagnetics. We present interpolation methods new to the geo-sciences that conserve flux and line integrals for Arakawa D, respectively Arakawa C, stagggered fields.

This talk should be of interest to anybody in need to regrid velocity and other vector fields whose components are staggered with respect to each other.

"Code without tests is bad code.  It doesn't matter how well written it is; it doesn't matter how pretty or object-oriented or well-encapsulated it is.  With tests, we can change the behavior of our code quickly and verifiably.  Without them, we really don't know if our code is getting better or worse."   [FEATHERS]

A strong statement, but it does bring home the vital role of testing in software development.  Join us at the Boulder Outlook Hotel for:

Strategies, motivations, and influencing adoption of testing for scientific code

Ian Truslove, Erik Jasiak, NSIDC

Computation and programming are increasingly inescapable in modern Earth Sciences, but scientists and researchers receive little or no formal software engineering or programming training.  At the same time, research into the reproducibility of other academic papers exposing disappointingly low rates of repeatability and high-profile retractions due to computational or data errors increase the onus on researchers to write repeatable, reliable, even reusable programs; in other words, "write better code".

Software engineering has plenty to say on the matter of "better code": metrics, methodologies, processes, tools...  Of course, none are indisputable and none provide absolute guarantees.  One seemingly obvious technique - testing - has enjoyed a renaissance in incarnations such as unit testing, and with approaches such as test-driven development (TDD) and behavior-driven development (BDD).

Based on our experience at the National Snow and Ice Data Center (NSIDC) with unit testing, TDD and BDD, we present a set of recommendations to scientific and research programmers about some techniques to try in their day to day programming, and possibly provide some inspiration to aim for more comprehensive approaches such as BDD. We will highlight some use cases of various types of testing at the NSIDC, discuss some of the cultural and management changes that occurred for programmers, scientists and project managers to consider and adopt processes such as TDD, make recommendations about how to introduce or expand rigorous code testing practices in your organization, and discuss the likely benefits in doing so.

The Research Data Alliance: Creating the culture and technology for an international data infrastructure

Mark Parsons, Managing Director, Research Data Alliance/U.S.

All of society’s grand challenges -- be it addressing rapid climate change, curing cancer and other disease, providing food and water for more than seven billion people, understanding the origins of the universe or the mind -- all of them require diverse and sometimes very large data to to be shared and integrated across cultures, scales, and technologies. This requires a new form and new conception of infrastructure. The Research Data Alliance (RDA) is creating and implementing this new data infrastructure. It is building the connections that make data work across social and technical barriers. 

RDA launched in March 2013 as a international alliance of researchers, data scientists, and organizations to build these connections and infrastructure to accelerate data-driven innovation. RDA facilitates research data sharing, use, re-use, discoverability, and standards harmonization through the development and adoption of technologies, policy, practice, standards, and other deliverables. We do this through focussed Working Groups, exploratory Interest Groups, and a broad, committed membership of individuals and organizations dedicated  to improving data exchange.

HDF and The Earth Science Platform

Ted Habermann, The HDF Group

Interoperable data and understanding across the Earth Science community requires convergence towards a standard set of data formats and services, metadata standards, and conventions for effective use of both. Although large legacy archives still exist in netCDF3, HDF4, and many custom formats, we have achieved considerable convergence in the data format layer with the merger of the netCDF4 and HDF5 formats. The way forward seems clear as more groups in many disciplines join the HDF5 community. The data service layer has experienced similar convergence as OGC Service Standards are adopted and used in increasing numbers and connections across former chasms are deployed (ncWMS, ncSOS, netCDF/CF as OGC Standards). Many data providers around the world are in the process of converging towards ISO Standards for documenting data and services. Connections are also helping here (ncISO). Many groups are now working towards convergence in the conventions layer. The HDF-EOS and Climate-Forecast conventions have been used successfully for many datasets spanning many Earth Science disciplines. These two sets of conventions reflect different histories and approaches that provide a rich set of lessons learned as we move forward.

NOAA Earth Information Services and TerraViz

Eric Hackathorn, Julien Lynge, Jeff Smith, TerraViz, NOAA

Jebb Stewart, Chris MacDermaid, NEIS, NOAA

The NOAA Earth Information Services (NEIS) is a framework of layered services designed to help the discovery, access, understanding, and visualization of data from the past, present, and future. It includes a visualization component named TerraViz that is a multi-platform tool, running on desktops, web browsers, and mobile devices. The goal is to ingest "big data" and convert that information into efficient formats for real-time visualization. Designed for a world where everything is in motion, NEIS and TerraViz allow fluid data integration and interaction across 4D time and space, providing a tool for everything NOAA does and the people NOAA affects.

TerraViz is built using the Unity game engine.  While a game engine may seem a strange choice for data visualizations, our philosophy is to take advantage of existing technology whenever possible.  Video games are a multibillion-dollar industry, and are quite simply the most powerful tools for pushing millions of points of data to the user in real-time. Our presentation illustrated displaying environmental data in TerraViz at a global scale, visualizing regional data in “scenes” such as the flooding of the Washington DC area or rotating a coastal ecosystem in three axes, and developing environmental simulations/games like exploring the ocean floor in a submarine.

The NEIS backend similarly takes lessons from private industry, using Apache Solr and other open source technologies to allow faceted search of NOAA data, much as sites like Amazon and Netflix do.

We believe that to have an impact on society, data should be easy to find, access, visualize, and understand.  NEIS simplifies and abstracts searching, connectivity, and different data formats, allowing users to concentrate on the data and science.

Please contact us if you want to explore including your environmental data within NEIS/TerraViz or if you want to talk to us about developing custom visualizations or educational simulations to showcase your important data.

Chris Lynnes, Chief Systems Engineer of the Goddard DAAC, NASA, "The Earth Science Collaboratory"

The Earth Science Collaboratory is a proposed framework for supporting the sharing within the Earth science community of data, tools, analysis methods, and results, plus all the contextual knowledge that go with these artifacts.  The likely benefits include:

  • access to expert knowledge about how to work with data safely and efficiently
  • full reprocability of results
  • efficient collaboration within multi-disciplinary and/or geographically distributed teams
  • a social network to bring together researchers and data users with common interests

Currently, there are some nascent efforts to construct such a collaboratory.  However, by its very (inclusive) nature, this construction is likely to be most successful as an emergent process, evolving from many point-to-point connections to an eventual ecosystem of cooperating components supporting collaboration. 

In particular, we are actively seeking scientists and other potential users of such a collaboratory to provide an end user perspective of system functionality.   Would you find such a collaboratory helpful?   Do you have ideas about how it could be better?  Would you like to influence its design?  Those that are actively engaged will be heard and could end up with a tool that particularly suits their needs.   If this role interests you, please attend this talk and/or otherwise let us know of your interest.

LaTiS is a data model, a data analysis API, and a REST-ful web service for accessing scientific data via a common interface.

The LaTiS data model provides a scientific domain independent, unifying, mathematical foundation for describing datasets that captures the functional relationships between parameters. The Scala implementation of this model provides an API for reading data directly from their native source, the ability to compute with high level abstractions appropriate for the task at hand, and options for filtering, transforming, and writing data in various formats.

This talk will discuss how these capabilities are used to enable a modular web service framework that can easily be installed and configured by a data provider, and that allows users to dynamically reformat a dataset, including its time representation, storage format, missing values, etc.

This talk will be a preview (i.e. beta release) of the talk I will give at UCAR Software Engineering Assembly Conference in April.

Yet more around semantics!   Please join us at the Boulder Outlook Hotel for:

Beth Huffer, Lingua Logica, "ODISEES: An Ontology-Driven Interactive Search Environment for Earth Sciences"

As part of an on-going effort at NASA Langley’s Atmospheric Science Data Center, and in cooperation with the Computational & Information Sciences & Technology Office at the Goddard Space Flight Center, we have developed a semi-automated method for finding and comparing equivalent data and climate model output variables across disparate datasets.  We will demonstrate an ontology-driven variable matching service that provides an automated mapping among comparable variables from multiple data products and climate model output products. The interactive user interface is driven by a queriable ontological model of the essential characteristics of data and climate model output variables, the products they occur in, the atmospheric parameters represented in the data, and the instruments and techniques used to measure or model the parameters. Queries of the ontology and triple store are used to match comparable variables by enabling users to search for those that share a user-specified set of essential characteristics. 

The application addresses an emerging need among Earth scientists to compare climate model outputs to other models and to satellite observations, and addresses some of the barriers that currently make such comparisons difficult.  In particular, the application

  • Eliminates the need for users to be familiar with the multiple data vocabularies and standards that exist within the Earth sciences community; and
  • With a few mouse clicks, provides ready access to the information needed by scientists to understand the similarities and differences between two or more data or climate model products, enabling them to quickly determine which products best suit their requirements.

"Informing Science Policy: the Role for Scientists and Engineers"

A Panel Discussion

Note: This meeting will be held at NEON Headquarters, instead of our usual location.  Details below.

This month Brian Wee, Steve Aulenbach, and I are delighted to have representatives from law, government and science come together to discuss various aspects of science policy.  We've asked them to consider questions like these:

  • What does "science policy" mean to you? To your organization? What impact does it have?
  • What are the roles in science policy and what impacts do they have? Who are the main players?
  • How have you or your organization tried to impact science policy? What worked and what did not work? What did you learn?
  • How does one prepare for a science policy discussion? Any do's and don'ts?
  • Scientists and engineers are trained to think and communicate in certain ways. Should those same skills be applied to policy discussions?
  • If someone wanted to move more heavily into science policy, how would you advise them? What career moves would be good? Any bad career moves?

Dave Fulker, President, OPeNDAP, Inc., A (Very) Rough Idea: Raster Binning and Masking Services (see attachment)

I'll sketch my idea for a new type of data query/response service built (perhaps for EarthCube) around a standardized space-time raster that has a dual function. Tentatively dubbed "Raster Binning & Masking Services" or RBinMasks, users would gain a (potentially standard) way to specify (irregular) space-time regions of interest and a (potentially standard) way to gain information about the space-time distributions of pertinent data, without -- or before -- retrieving actual values.

Bridging Data Lifecycles: Tracking Data Use via Data Citations

April 5-6, 2012 at the University Corporation for Atmospheric Research in Boulder, CO.

Please join us for a workshop on data citation and data use geared to the interests of data manager specialists and librarians. Data citations are increasingly seen as being critical to enabling scientific results to be traced back to their underlying data. Data citations also promote the transparency of scientific work by making data more discoverable, and enable scientists, data managers, and data centers to be credited for producing useful data. Presentations will focus data lifecycles, current options for data citation and data reuse, and will highlight pilot projects in implementing citation standards and practices. Dr. Tim Killeen, Assistant Director for Geosciences at the National Science Foundation will provide the keynote address. Other presenters include Joan Starr of the California Digital Library and Mark Parsons of the National Snow and Ice Data Center. Additional speakers are listed on the workshop web page.

Panel Report and Discussion on Recent NSF EarthCube Charette

According to the EarthCube web site, http://earthcube.ning.com/, "The goal of EarthCube is to transform the conduct of research by supporting the development of community-guided cyberinfrastructure to integrate data  and information for knowledge management across the Geosciences."

During November 1 - 4, 2011, the NSF held the EarthCube Charette in Washington, D.C.   The Charette was intended to be "the first stage in an iterative process to build a community-based cyberinfrastructure,"  and an "opportunity for face-to-face interaction and feedback among groups that are suggesting designs for EarthCube and a broad, diverse set of the geosciences and cyberinfrastructure communities."

Panel members for our meeting are Charette attendees who will share their thoughts and experiences. Perhaps we'll finally understand the answer to the question, "What is a charette, anyway?"

Panel members:

Michael Wiltberger, HAO/NCAR

Russ Rew, Unidata/UCAR

Seth McGinnis, CISL/NCAR

Scott Peckham, CSDMS/INSTAAR/CU Boulder

Chris MacDermaid, CSU CIRA Fort Collins/NOAA ESRL

Panel discussion on Peer Review of Scientific Data

"Data centers have few established practices for peer review of data. Indeed there is no clear definition of what peer review of data really means. Is it a review of data accuracy or validity, or is it a review of data documentation to ensure complete description of uncertainty and context? Despite these challenges, scientists and data managers have a professional and ethical responsibility to do their best to meet the data publication goals asserted by AGU."    [Parsons, M. A., R. Duerr, and J.-B. Minster (2010),Data Citation and Peer Review, Eos Trans. AGU,91(34), 297, doi:10.1029/2010EO340001.]

Wednesday, September 21, 2011, 4:00 - 6:00, Millenium Hotel's Boulder Creek Living Room.

Note that the Millenium is graciously providing us this room including wireless connectivity without charge.  Please attend this meeting and consider purchasing a drink or appetizer to support the Millenium and our continued use of this room and its amenities.

Who:

Mark Parsons, Program Manager, Senior Associate Scientist, NSIDC

Matt Mayernik, Research Data Services Specialist, NCAR library

Eric Kihn, Deputy Director of the National Geophysical Data Center, NOAA

Karen Simmons, Experiment Manager for Galileo UVS/EUV instruments and archivist for data from Voyager and Galileo. Also, current archive specialist  on an archiving grant through NASA for very old (1969, 71,75 etc) planetary data., provider to NASA PDS, LASP

Rob Wilson, Scientist studying magnetospheres of the outer planets, using PDS data, LASP

Topics for discussion include:

- Should data peer review differ from conventional document review?  If so, how and why?  What does peer review of a dataset really mean?

- How are peer-reviewed datasets certified?  Everyone knows the peer reviewed journals and has some notion of their impact.  How does that work for data?

- Who conducts the review?  Who is the "editor" to coordinate the review?

- Does peer review imply more responsibility or accountability for the data "publisher"?

- One critical discussion should be about what facility is accepting the data and how they operate, what requirements they have for peer review and discussion of how well that's worked in the past. Their perspective is often quite different from that of a scientist.

Please join us in this discussion! 

The discussion will be followed by a short business meeting for feedback and planning purposes.

NOTE THE NEW LOCATION:  This meeting will be held at the Millenium Hotel in the Boulder Creek Living Room.  This private room is adjacent to a bar where food and beverages can be purchased and brought into the meeting.  

Note that the Millenium is graciously providing us this room including wireless connectivity without charge.  Please attend this meeting and consider purchasing some comestible fare to support the Millenium and our continued use of this room and its amenities.

At the BESSIG planning meeting on Wednesday we scheduled meetings for Thursday, June 23 and Tuesday, July 19, 4:00 PM.  (See our Calendar ).  These meetings will be BLASTs: BESSIG Lively Activists Speaking Topically.  That means people are on deck to present their work, area of interest, or whatever.   The goal is to for us to get to know each other and our areas of expertise better, and to allow for discussion.  Thus, speakers will present for as short or as long as they wish as long as it's "not too long" (TBD).   Some speakers may get bumped until later, and that's okay.  We'll also work in some time for socializing.

We have six speakers that will be ready on June 23, see the Calendar item to see who they are.  We're looking for people to sign up for July 19.  If you're interested in sharing with us, go to the that calendar event and put your name on the list under the "Description" section.

We also updated the table of Meeting Topics with some ideas to incubate.   We found it particularly liberating to nominate topic organizers that weren't actually present at the meeting.   Feel free to update the table with your ideas about meeting topics and organizers.

Also, the group paid it forward by contributing $40 to a kitty (including pledges) for snacks for our next meeting.  Thanks, guys!!

An important meeting topic was: beer.   There is interest in having beer at our meetings, but institutions have severe limitations on alcohol.  Here at CU a recent update of the alcohol policy muddied the waters sufficiently that what is and is not allowed is unclear and is under investigation by our staff.   More on this to follow.   Suggestions?

Purpose:  Plan meeting topics for upcoming year, and hobnob

When:  Wednesday, May 18, 2011, 4:00 - 6:00 PM

Where:  Room A200, LASP Space Technology Building, 1234 Innovation Drive, Boulder, Colorado

As we've not identified a talk topic for this meeting, we'll use our time to plan meeting topics and, as much as possible, a schedule for the upcoming year.   Please come to the meeting with your calendar and specific ideas about meeting topics you would like to hear about or might be interested in presenting.   We'll also get to know each other a little better over some light snacks.  If all goes well we could be done early.

I have started a Meeting Topic and Organizer List, check it out.

If you can't make this meeting but would like to provide input, send an email to bessig.info@lasp.colorado.edu (which currently comes to me, Anne).

LASP is located on the University of Colorado's East Campus Research Park.  A map and directions are available on the LASP locations page.  The building sits just off Colorado Avenue, immediately adjacent to CU's new, very large biotechnology building that is currently under construction.   Look for the tallest cranes in town, we're next door to the East.  Free parking is available.

At our most recent meeting we decided to meet again on Wednesday, 5/18 from 4:00 - 6:00 with this schedule:

4:00 Talk (TBD)

5:00 Business meeting

The group agreed to discuss talk topics and speakers via the web site. 

In retrospect, I think this is a very tight schedule, as in general it would be good to provide a speaker with a two week lead time.  Plus, we have to find someone that can come at the particular hour.  I'm a little nervous about making this goal.

Please contribute to our discussion about identifying a speaker and topic for this upcoming meeting in the Discussion section of the web site.   Thank you!

If anyone is available to sponser snacks or beverages for this meeting please contact me.

I'm really pleased about our launch meeting last night.  Thank you to all who attended and also those who showed interest but could not attend.

We had roughly 45 people in attendance from 10 organizations: LASP, NDP LLC, NEON, NOAA, NSIDC, CU Boulder Research Computing, Tech-X Corporation, UNAVCO, UCAR, and UCAR/Unidata. 

Ted led us off with a talk about "Convergence and Trust in Earth Space Science Data Systems": Habermann_ConvergenceAndTrust.  "Convergence" refers to convergence towards standards and best practices that simplify exchange and use of data.   Simplification of that aspect of science is helping us move from data to information to knowledge and finally to wisdom.   Generally data producers are involved in transforming data to information, data consumers are involved in transforming information to knowledge, and it takes the community to translate knowledge to wisdom.   This path leads to the question of trust: given that we're in an age where people use data and may not know who the data provider was, let alone have communicated with them, how do we say with certainity that our results are correct?  This leads to the issue of trust.  The topic of trust, being an over arching issue, played a big role in our subsequent discussion at our business meeting.  Discussion notes from that meeting will be available soon. 

Dave Fulker entertained us with a witty, erudite joke followed by a talk on "Standard Mechanisms for Data Exchange", practices that became "standard" by virtue of being commonplace: Fulker_StandardMechanismsForDataExchange.  Dave made a comparison between the history of artifacts and what those artifacts enabled, e.g., writing instruments enabled numerical symbols, scrolls/books/libraries enabled tables and relations, etc.  Currently, computers in science have enabled data management, analysis, and visualization as library functions or APIs, e.g., library functions for data formatting.  Regarding data analysis and visualization, the power of a system is directly related to the generality and richness of its underlying data model.   And now, the web has enabled near real time data flows and remote access to data.

These talks were relevant in our business meeting where we brainstormed about what this group might be or do, what our goals might be, who is available for contributing and what to do next.   In Ted's terms, we are in a stage of ferment, trying to focus our energy as a community.   Some common themes emerged, such as serving as a resource for those trying to learn how to build good systems.  Another theme was trust: how is it currently earned, how can we ensure its viability in our escience world?   Are there projects for us there?  Notes from this section of meeting are available off the Discussion section.

We decided to meet again in month, on Wednesday, 5/18, from 4:00 - 6:00.  (If anyone is available to sponser snacks or beverages for this meeting please contact me.)  The first hour will be a talk.  The second hour will be a business meeting.   The group is tasked with identifying a speaker for the 4:00 time slot.

I really appreciate the strong interest and support I received in launching this group.  I'd like to stress here again that this is a community effort.  The more people contribute, the more successful we'll be as a group.  The good news is that there is a good number of us such that each individual effort does not have to be huge.  Please think about what you are able to contribute.

Watch our site as news about the upcoming 5/18 meeting develops.

5:00 Arrive

5:15 The Role of Standards for Data and Metadata, by Ted Habermann and Dave Fulker

A hallmark of science in the Internet age has been the increasing importance of means for exchanging digital data. Indeed the significance is so great that Turing Award winner Jim Gray dubbed this data-intensive pattern the "Fourth Paradigm of Science." Tightly linked with effective data exchange is a critical need for standards such that data providers and data users are, in essence, talking the same language. The authors will cover two aspects of this need: 1) Habermann will discuss important progress, international in scope, on standards for metadata (i.e., information about data) that are being widely adopted; 2) Fulker will discuss software and protocols that have, through patterns of use, served to significantly standardize the mechanisms for data exchange, including how complex data structures are digitally represented and serialized.
