Metacat is a flexible database storage system for XML formatted
|
23 |
666
|
jones
|
documents. Metacat models the structure of the XML document, therefore
|
24 |
1003
|
berkley
|
allowing storage of XML documents with arbitrary schemas. Metacat supports
|
25 |
1307
|
jones
|
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.

In this release, the structure of the xml_access table was changed and a new
|
36 |
|
|
table, xml_accesssubtree was added. If you try to update a previously
|
37 |
|
|
installed Metacat, you should run a script file to updated the table structure
|
38 |
|
|
before installation.
|
39 |
|
|
For Oracle user: At the SQLPLUS prompt type the following -
|
40 |
|
|
@src/reviseformetacat13.sql
|
41 |
|
|
For Postgresql user: At install directory prompt type the following -
|
42 |
|
|
psql exp < src/reviseformetacat13_postgres.sql
|
43 |

After installation, user should run "ant schemasql" command to register EML2
|
46 |
|
|
schema in xml_catalog table.
|
47 |
|
|
|
48 |
|
|
