FEA Data and Information Reference Model (DRM): the Interoperability Message Presented by Eliot Christian, USGS based on work of ISO/IEC JTC1/SC32 Data Management Subcommittee chair, Bruce Bargmeyer (NIST, EPA, and LBL)

2 Registries as Applied to Data/ Information/ Knowledge Management  Several types of “ registries ” commonly used in data / information/ knowledge management  Various registries have related content, extended and utilized in different ways  The registries vary according to:  intended purpose  granularity of contents  the level of semantics management.

3 Types of Registries Common Content OASIS/ebXML Registries Common Content ISO Registries Common Content Ontological Registries Common Content Database Catalogs Common Content CASE Tool Repositories Common Content UDDI Registries Software Component Registries Common Content

4 Types of Registries: ISO Metadata Registries  Registers Data Elements, components of data elements and groups of data elements (e.g., country codes for customer place of residence)  Includes data element concepts, data elements (including representation), value domains, and (multiple) taxonomies  Emphasis on semantic information such as definitions of data elements and value meanings, and stewardship responsibilities Common Content ISO Registries

5 Types of Registries: Database Catalogs/Data Dictionaries/ Repositories  Registers schema, integrity & operational information  Includes all elements of database schemas: data elements, relations, integrity constraints  Emphasis on information required to make database systems work for queries, etc., not semantic management Common Content Database Catalogs

6 Types of Registries: Universal Description, Discovery, and Integration (UDDI) Registries  Registers Web-based Business Services  A White page directory of the business activities of firms  Emphasis on interface specifications Common Content UDDI Registries

7 Types of Registries: Case Tool (Encyclopedias/Repositories)  Registers data models and application program logic  Includes information needed to create a database and potentially the program code for a system, including database schemas  Emphasis not on semantic management Common Content CASE Tool Repositories

8 Types of Registries: Ontological Registries  Registers Concept Structures  Includes relations among concepts (subsumption, inheritance, … ) and axioms for inference among concepts, e.g., temporal/spatial reasoning, etc.  Emphasis is on semantics Common Content Ontological Registries

9 Types of Registries: Software Component Registries  Registers reusable software components built on specific vendor platforms such as EJB, COM, CORBA IDL etc.  Includes basic common elementary objects and object patterns  Emphasis on reusability of software component to build flexible and standardized business systems. Software Component Registries Common Content

10 Types of Registries: OASIS/ebXML XML Registries  Registers XML Artifacts  Includes schemas and DTDs (XML schemata typically relate to a paper form, EDI document, or reporting requirement)  Emphasis on syntactic (structure) information Common Content OASIS/ebXML Registries
