Abstract: This article introduces the methodology of intermediary schemas for complex metadata environments. Metadata in instances conforming to these is not generally intended for dissemination but must usually be transformed by XSLT transformations to generate instances conforming to the referent schemas to which they mediate. The methodology is designed to enhance the interoperability of complex metadata within XML architectures. This methodology incorporates three subsidiary methods: these are project-specific schemas which represent constrained mediators to over-complex or over-flexible referents (Method 1), templates or conceptual maps from which instances may be generated (Method 2) and serialised maps of instances conforming to their referent schemas (Method 3). The three methods are detailed and their applications to current research in digital ecosystems, archival description and digital asset management and preservation are examined. A possible synthesis of the three is also proposed in order to enable the methodology to operate within a single schema, the Metadata Encoding and Transmission Standard (METS).
Keywords: XML; intermediary XML schemas; metadata; interoperability; digital asset management; digital preservation; METS; metadata encoding and transmission standard.
