XML Data Servers
Database indices are created for each DTD based on the defined COVAX Access
points,
Access via HTTP protocol,
XML servers include Software AG's Tamino data server
and IXASOFT TEXTML server.
Multilingual User Interfaces
Multilingual user interfaces and document labels (six languages) are available for all DTDs.
XSLT is used to transform XML results into HMTL presentations that include:
Complete documents based on the native XML document (EAD, MARC, AMICO
or TEI metadata).The documents are distinctive based on their collection types,
Short Dublin Core results,
Full Dublin Core results,
Native XML documents are also available for download.
For display, Dublin Core is dynamically generated from the native XML document.
Within the project exploitation plans, a central Dublin Core metadata XML repository will
be included in order to gather metadata about resources that cannot or will not be
completely converted to a particular XML DTD.

The following graphs represent the difference between the two approaches described
above:
As a basic requirement, both models use a uniform metadata format, the Dublin Core
Metadata Standard.The Dublin Core Standard was initially brought forward to bridge the
differences between the many distinct description practices in use in archives, libraries and
museums by reducing the number of elements to describe a cultural object to a total of 15.
In addition, the Dublin Core metadata standard provides a set of qualifiers Fully Qualified
Dublin Core - to give institutions the opportunity to further describe the cultural object.
Today, it is increasingly used to facilitate resources discovery across sector boundaries.
