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.
