Breakout Sessions #1, 1:30-3:30 p.m.

Technical Breakout 1a - Building Better Metadata

Time Session Leader
1:30-2:15 FGDC and ISO Geospatial Metadata Standards Ted Habermann
2:30-3:15 The Proliferation of Metadata Standards and the Evolution of NASA’s Global Change Master Directory (GCMD) Standard for Uses in Earth Science Data Discovery: A growing number of metadata "standards" are being created within the Earth science community, adding to the users' dilemma in choosing the "right" standard. The Global Change Master Directory (GCMD) GCMD uses the Directory Interchange Format (DIF) standard, because it offers "controlled vocabulary" options and thus provides normalized searches for metadata discovery. This standard thus serves capably as the GCMD's core for locating data and in no way diminishes its adherence to other broader, required standards. This presentation will demonstrate the effectiveness of the DIF standard and its attractiveness in the discovery of metadata and its easy translations to other standards. The DIF standard continues to evolve to capture additional fields that are useful within the community [presentation slides] Jianpinig Mao

There is the possibility of an additional educational metadata best practices session as well (TBA)

Technical Breakout 1b - Semantic Web

First hour

  • Developing ontologies (has some use case elements in it)

Presentation Slides

Second hour (depending on audience) - not presented, Watch the Summer 2008 meeting schedule for these tutorial:

  • Query Languages
  • Rules
  • Use cases for semantic web development

Issue Breakout 1 - Air Quality Cluster Meeting

Session Topics

  • Introduction and overview of the ESIP Air Quality Cluster Activities
  • Capturing air quality project networking through metadata pages (DataSpace and DataSheets) and their relationship to metadata catalogs
  • ESIP preparation for the EPA Air Quality Data Summit
  • Overview of demo session at the evening reception

View AQ Cluster Session page for more information

Breakout Sessions #2, 3:45-5:45 p.m.

Technical Breakout 2a - Registering Data and Services (GCMD, GOS)

Time Session Leader
3:45-4:15 Registering Earth Science Data and Data Related Services Using NASA’s Global Change Master Directory (GCMD): The Global Change Master Directory (GCMD) offers a robust and intuitive web-based authoring tool “docBUILDER” for creating and validating a variety of Earth Science metadata. The goal of this presentation is to discuss the benefits of registering metadata in the GCMD and to provide the information needed to create metadata that can be validated before it is made available to the public. Additional methods for metadata creation and ingestion including metadata harvesting will also be discussed. [presentation materials] Tyler Stevens
4:30-5:00 Registering ESIP product & services with Geospatial One-Stop (GOS): This talk will provide an overview of ESIPs relationship with Geospatial One-Stop, and focus in detail on the process of registering ESIP products and services with Geospatial One-Stop. Come learn how to publish your metadata holding to GOS, and learn why it will be beneficial to both individual members and ESIP as whole to do so. (presentation) John Kozimor
5:15-5:45 Registering air quality web services with metadata catalogs Stefan Falke

Technical Breakout 2b - Developing an Ontology for Services

  • Classifying services and describing service interfaces to support "smart" workflow composition (presentations by Rahul Ramachandran & Liping Di & Benno Blumenthal)
  • Begin development of core services ontology based on our use cases
  • Collect current service ontologies (OWL-S, WSDL, etc.)
  • Collect current data-type ontologies and identify attributes (e.g. data mining tends to be agnostic to the

science use/meaning of the data, whereas geospatial processing services very often do need to know the science meaning, e.g. wavelength of an image)

  • Use CMAP to iterate on Data Type and Service Ontology concept maps (Rahul to set up)
  • Exchange experiences with semantic software stacks (triple stores, inference engines, rules engines, etc.)
  • Benno Blumenthal's slides [1]
Other presenters - add your slides here.
Background on Services, e.g. use cases (Pfox) presentation

Issue Breakout 2 - Water Management Cluster Meeting

Session Leaders Tim Owen, NOAA/NCDC and Will Pozzi, CREW/WaterNet
Session Rapporteur Carol Meyer, ESIP Federation
Session Objectives
  • To connect portal and ontological development in water management with user requirements for products, services, and data discovery tools; and
  • To consider these connections in the context of an emerging climate cluster (to include water management, air quality, and the carbon cycle)


Session Notes

Agenda
Time Session Leader
3:45 Opening Remarks Dick Wertz
3:50 Preamble Presentations: Portal Synergies in Water and Drought and Ontological Development as a Foundation for Products and Services in Water Management Tim Owen, Will Pozzi, Jeff Arnfield, and Lola Olsen

Potential Discussion Topics
  • Ontologies
  • Metadata/registries
  • Inventories
  • Knowledge directories
  • Data discovery from GCMD portal perspective (ECV, WaterNet, CUASHI)
  • On-line catalogues, networking, and screen scraping capabilities
  • Standards and service-oriented architecture (USGEO/ADM perspectives)
  • Matching resources (data tools, models, research papers, visualization overlays) with accessibility (RISA/AASC/REACT perspectives)
  • Semantic capabilities – textual and graphic – of targeted user groups


One-Pagers
  • Brand Niemann's work at EPA [2]
