Provides a common set of terminology and definitions A framework for describing resources and processes Enables computer based interoperability ISO standards (19115, 19115-2) to
4
Not just for discovery Supports long term understanding Living documents that need care and feeding Data experts provide standard metadata as early as possible in the data life cycle Data stewards maintain records and update annually
5
Metadata standards evolve -> metadata records should evolve and take advantage of new capabilities Each data manager/steward is responsible for transitioning their metadata records to ISO Programmatic transform takes care of ~90% encourage stewards to use this as an opportunity to also improve content
6
Aggregation - identify related projects and programs Identifiers - lotso' ways to provide ids Repeatable responsible parties Descriptive online resources Services Integrates GML Scope of content is flexible Strong technical support via XML Duh – it’s international

Docucomp Docucomp Supports reusable components for editing and managing metadata Web Accessible Folders (WAFs) Web Accessible Folders (WAFs) Reports on metadata quality Views Publication mechanism Geoportal Geoportal Supports discovery of NGDC geophysical resources Federated search with other data centers
9
Review Content Are URLs up-to-date? Are contacts, phone numbers and emails up-to-date? Are keywords still up-to-date? Do all of your archive holdings have metadata? When was the metadata last updated or reviewed?
10
How well does the metadata describe the resource? Is the scope of the metadata granular enough to describe the resource? Is quality and data history included? Does the distribution link take users to that data access page?
11
Have the metadata standard(s) and/or metadata tools evolved? Are there new features that could help document your data better? Interoperability Are there ways to re-using metadata programmatically? Distributing metadata with data data download? Providing links to metadata for more information from data distribution sources?
12
Related Projects and Communities Are there expectations and guidance available from projects and communities? Is the metadata content compatible with projects and communities? Are there other projects and communities that the metadata can be a part of?

Metadata Completeness

Reports: URL Checker, Validation, Consistency Checker
23
Meta”date” once – document many times Standard metadata supports interoperability and sharing ISO provides new capabilities for documenting our datasets (see upcoming slide)
24
Robust content versus expertise time Integrated metadata portals seem to not work as metadata providers hope “I don’t have the tools I need” to create metadata Training new tools, standards and best practices “standards don’t help me or my users”
25
Integrate/re-use metadata with Digital Object Identifiers (DOIs) Integrate/re-use metadata with Ontologies Hierarchical relationships across disparate yet related or similar metadata Metadata for Services
