Towards Federated Referatories

Abstract:

Metadata usage often depends on schemas for metadata, which are important to convey the meaning of the metadata. We propose an architecture where users can extend the schema used by a system for managing referential metadata. Users can plugin new schemas and install custom filters for exporting metadata, so that users are not forced to limit their metadata to a fixed schema. The goal of this architecture is to provide users with a system that helps them managing their referatory, enables them with powerful tools to adapt the tool to their metadata, and still makes it possible to collect the metadata of several users in a central storage and exploit the common facets of the metadata. Our system is based on a specialized schema language, which has been built on top of the XML schema languages XML Schema and Schematron.
