1. Nancy J. Hoebelheinrich, Metadata Coordinator, Stanford University 1 Metadata for the NGDA: Developing a Shared Approach Joint UCSB / Stanford meeting at Stanford University May 23, 2005

2. Nancy J. Hoebelheinrich, Metadata Coordinator, Stanford University2 Topics for discussion today Purpose: initiate discussion of approach to MD within federated environment Overview of what “metadata” covers Suggested approach, given federation

3. Nancy J. Hoebelheinrich, Metadata Coordinator, Stanford University3 Metadata within a federation – what can we expect? Basis of metadata requirements  Type of repository  Planned services for given constituency  What data providers can provide  What repository can contribute Contextual realities: technical, legal, economic

4. Nancy J. Hoebelheinrich, Metadata Coordinator, Stanford University4 Overview of what MD covers Descriptions of object and collections Documentation of business rules = administrative metadata Transport and packaging of object and associated metadata

5. Nancy J. Hoebelheinrich, Metadata Coordinator, Stanford University5 Descriptive Metadata for NGDA Discovery /searching for object / item  FRBR (basic level of functionality): find identify select obtain  Geographic necessities: location  Metadata Registries (see ISO/IEC 11179, Information Technology -- Metadata Registries) Collection level for inclusion in catalogs and emerging collection registries  IMLS Collection registry, NSDL, CORDRA

6. Nancy J. Hoebelheinrich, Metadata Coordinator, Stanford University6 Administrative Metadata – business rules Collection & MD management Technical in conjunction with format registries Preservation – documentation of current & past status of, preservation actions upon digital objects Rights as necessary to store, display, use

7. Nancy J. Hoebelheinrich, Metadata Coordinator, Stanford University7 A little more on Rights Documentation of rights holders Provide facilitation of user authentication / authorization to protect privacy & allow / restrict use of content Public statement of above to display to users

8. Nancy J. Hoebelheinrich, Metadata Coordinator, Stanford University8 Transport and packaging Structural metadata – ordered components of digital object and relationships among them Crafted, standardized packages for (at least) submission, and archiving of content & MD to NGDA

9. Nancy J. Hoebelheinrich, Metadata Coordinator, Stanford University9 Suggested approach, given federation: Use of standards (e.g., FGDC, qDC or MODS Light, MIX, XML, GML?, PREMIS, METS or XFDU?) Develop core set of MD classes & elements within, based on standards Use metadata, format, collection registries as possible

10. Nancy J. Hoebelheinrich, Metadata Coordinator, Stanford University10 Plan of action: Investigate / analyze standards to use Obtain / query sample collections of content & metadata Develop & recommend core set of metadata for geospatial content in conjunction with broader geospatial community Work with developers to create / identify tools, services, workflow
