Abstract

This paper describes a conceptual framework and methodology 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 conclusion identifies future research directions.
