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.
