This is Metacat, a flexible database storage system for XML formatted
21
documents. Metacat models the structure of the XML document, therefore
22
allowing storage of XML documents with arbitrary schemas. The current
23
implementation stores data in a backend Oracle RDBMS, but was designed
24
to support other RDBMS systems as well. The server supports XML document
25
storage, retrievel, query, validation, and transformation (using the XSLT
26
stylesheet language).  In addition, there is a mechanism for replicating
27
the database to other metacat instances for backup and load balancing
28
purposes.  Metacat currently uses an LDAP database for authenticating
29
users, but was written to accomodate other authentication services as well.
