metadata management and services in the GoC including representation from central
agencies, enterprise project teams like the CMS Team, RDIMS and GOL Gateways and
Clusters initiative.
Scope
The scope of the Web Services Sub Working Group will be two fold;
Identify and recommend the components and standards necessary to create and
manage enterprise Web Services required to support metadata management and
implementation,
Recommend and pilot specific Web Services to demonstrate that the standards and
components will support the management of metadata creation and interoperability
for functions such as content and records management, information search and
retrieval, access to and sharing of metadata syntax and semantics associated with
controlled vocabularies, taxonomies and other metadata values.
Objectives
