25 Thomas D. Wason IMS Project Feb. 1999 25 XML Instantiation Frag. Preliminary

26 Thomas D. Wason IMS Project Feb. 1999 26 Role of Meta-Data Tools

27 Thomas D. Wason IMS Project Feb. 1999 27 XML Editor Screen Shot

28 Thomas D. Wason IMS Project Feb. 1999 28 The User and Meta-Data The user wants to search for resources. The user wants to create labels for resources.

29 Thomas D. Wason IMS Project Feb. 1999 29 Meta-Data Instantiations The meta-data about resources is located in meta-data repositories.

30 Thomas D. Wason IMS Project Feb. 1999 30 Meta-Data Registry Information about the meta-data is located in a meta-data registry.

31 Thomas D. Wason IMS Project Feb. 1999 31 Meta-Data Profiles There may be additional information available in profiles.

32 Thomas D. Wason IMS Project Feb. 1999 32 Meta-Data System The meta-data system maintains information about what is in the meta-data.

33 Thomas D. Wason IMS Project Feb. 1999 33 Meta-Data Registries

34 Thomas D. Wason IMS Project Feb. 1999 34 Evolution of Meta-Data Different groups want different meta-data. The evolution of meta-data within IMS is managed via registries.

35 Thomas D. Wason IMS Project Feb. 1999 35 Base Type May Be Extended 1. Extend the allowable content domain of a given meta-data term, such as use of additional or alternative vocabularies. 2. Specialize a term by refining its constraints (e.g., obligation is changed from "optional" to "mandatory") 3. Introduce new terms into an existing meta-data set using concepts defined in a standard dictionary 4. Introduce new concepts into a dictionary, or create a brand new dictionary with a certain known relationship to the other dictionaries in existence

36 Thomas D. Wason IMS Project Feb. 1999 36 Meta-Data Type Library Library of schema types derived from a common base Base –Item –Module –Tool

37 Thomas D. Wason IMS Project Feb. 1999 37 Registration Needs Dictionary elements Schemas Value domains (vocabularies and taxonomies)

38 Thomas D. Wason IMS Project Feb. 1999 38 Meta-Data Schema Registry

39 Thomas D. Wason IMS Project Feb. 1999 39 Hierarchy of Registries

40 Thomas D. Wason IMS Project Feb. 1999 40 Balance of Control and Extension Types defined within registries provide control of meta-data instantiations. Defined methods of extending the meta-data hierarchy provide freedom to create new properties and types.
