  This paper describes a prototype of extended XDB. XDB is an open-source and
extensible database architecture developed by National Aeronautics and Space
Administration (NASA) to provide integration of heterogeneous and distributed
information resources for scientific and engineering applications. XDB enables
an unlimited number of desktops and distributed information sources to be
linked seamlessly and efficiently into an information grid using Data Access
and Retrieval Composition (DARC) protocol which provides a contextual search
and retrieval capability useful for lightweight web applications. This paper
shows the usage of XDB on common data management in the enterprise without
burdening users and application developers with unnecessary complexity and
formal schemas. Supported by NASA Ames Research Center through NASA Exploration
System Mission Directorate (ESMD) Higher Education grant, a project team at
Fairfield University extended this concept and developed an extended XDB
protocol and a prototype providing text-searches for Wiki. The technical
specification of the protocol was posted to Source Forge (sourceforge.net) and
a prototype providing text-searches for Wiki was developed. The prototype was
created for 16 tags of the MediaWiki dialect. As part of future works, the
prototype will be further extended to the complete Wiki markups and other
dialects of Wiki.
