•In order to reduce costs associated withmanaging metadata, we want to enableinterchange of metadata includingterminology between metadata registries.

•Organizations that are responsible forparticular terminology and data elements canpropagate these changes to other 11179metadata registries.

•We capture a concept with a definition.

•We assign unique identifiers to uniquelyidentify concepts.

•There are potentially many terms associatedwith any concept, and many conceptsassociated with any one term.

•Each term has a context from which it isextracted.

•It is common to alphabetize terms anddemonstrate many senses of a term (e.g.,dictionary, glossary, key word list).

•Terms within a specific context may also bestored for a particular subject area.

•We can alphabetize terms so people can lookup and see all the concepts associated with aparticular term.

•Specialized information, or subject matterspecialties gather and store terms specific to aparticular context (e.g., legal dictionary,medical glossaries, etc.).

•Deployment technologies: printed, on-line

•Another way to structure terminology is intoa thesaurus.

•A thesaurus has a hierarchical realtionship(NT, BT, UF). We add value by buillding astructure which is more informative than adictionary.

•Thesauri can be deployed in the form ofpublished books, software, or used to feedsearch engine applications.

•We organize our terms into data element.

•Terms can be used in names, definitions, andvalues.

•The way to access all this data is by term.

•In our metadata registry we want to be ableto view this information by the term name.

•Data elements are organized into the designof data bases, and can be used to performqueries.

•Data elements can be assembled intomessage content (I.e., message sets,transaction sets, information bundles, flatfiles, etc.) and can be deployed using EDImessages and other forms of communication.

•Terms and data elements can be organizedinto documents and published as reports,regulations, included in legislation, etc.

•A fourth way to structure terminology is intoontologies. Ontologies have rich structuresof relationships (generalization,specialization, inheritance).

•Terms can be used to drive IIS’s that utilizequery agents, wrapping agents, mediators,and similar technology to access data ongeographically dispersed, disparate sources.Example: an ontology might be structured toinclude table, data elements, and data elementvalues, so that queries could be constructedusing these ontological terms and resources.Queries are mapped to this ontology, thusenabling data to be integrated withoutrequiring all resources to use the exact sameterms in each system.
