Metacat is a flexible database storage system for XML formatted
|
|
23
|
documents. Metacat models the structure of the XML document, therefore
|
|
24
|
allowing storage of XML documents with arbitrary schemas. Metacat supports
|
|
25
|
several databases on the back-end, including Oracle, PostgreSQL and SQL
|
|
26
|
Server. The server supports XML document storage, retrievel, query,
|
|
27
|
validation, and transformation (using the XSLT stylesheet language).
|
|
28
|
In addition, there is a mechanism for replicating the database
|
|
29
|
to other metacat instances for backup and load balancing purposes.
|
|
30
|
Metacat currently uses an LDAP database for authenticating users, but
|
|
31
|
was written to accomodate other authentication services as well.
