This is Metacat, a flexible database storage system for XML formatted
|
| 21 |
666
|
jones
|
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 |
861
|
jones
|
the database to other metacat instances for backup and load balancing
|
| 28 |
666
|
jones
|
purposes. Metacat currently uses an LDAP database for authenticating
|
| 29 |
|
|
users, but was written to accomodate other authentication services as well.
