In order to facilitate subject access interoperability a mechanism must be built that allows the different controlled vocabularies to communicate meaning, relationships, and levels of extension and intension so that different user groups using different controlled vocabularies could access collections across the network. Switching languages, the tools of controlled vocabulary compatibility, consist of a single layer that does not allow for a flexible control of the semantic levels of meaning, relationships, and extension or intension. This paper proposes a multilayered conceptual framework wherein the levels of meaning, relationships and extension and intension are each controlled as individual parameters, rather than in a single switching language.

This paper describes a conceptual framework and meth- odology for managing scheme versioning for the Semantic Web. The first part of the paper introduces the concept of vocabulary encoding schemes, distinguished from metadata schemas, and discusses the characteristics of changes in schemes. The paper then presents a proposal to use a value record–similar to a term record in thesaurus management techniques–to manage scheme versioning challenges for the Semantic Web. The con-clusion identifies future research directions.
