Thomas D. Wason IMS Project Feb The User and Meta-Data The user wants to search for resources. The user wants to create labels for resources.
Thomas D. Wason IMS Project Feb Meta-Data Instantiations The meta-data about resources is located in meta-data repositories.
Thomas D. Wason IMS Project Feb Meta-Data Registry Information about the meta-data is located in a meta-data registry.
Thomas D. Wason IMS Project Feb Meta-Data Profiles There may be additional information available in profiles.
Thomas D. Wason IMS Project Feb Meta-Data System The meta-data system maintains information about what is in the meta-data.
Thomas D. Wason IMS Project Feb Meta-Data Registries
Thomas D. Wason IMS Project Feb Evolution of Meta-Data Different groups want different meta-data. The evolution of meta-data within IMS is managed via registries.
Thomas D. Wason IMS Project Feb 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

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