Common use of Reference Architecture Clause in Contracts

Reference Architecture. The functions expected by the Metadata Management subsystem are implemented by two cooperating services: one taking care of the creation and management of Metadata Objects and Metadata Collections (Metadata Manager) and another taking care of the support to metadata object retrieval (XML Indexer) as depicted in Figure 31. • MetadataManager – this Service is responsible for managing the incoming requests for changing, accessing and manipulating metadata. It associates metadata with Information Objects, remove associations, returns metadata for a given object and updates associated metadata; • XMLIndexer – this Service is a generic XML Indexer service allowing to query the metadata by resolving arbitrary XQuery and XPath expressions against its managed content. It indexes homogeneous collections of XML data.
