Metacat

Version: 1.3.0 Release

In this release, the structure of the xml_access table was changed and a new

table, xml_accesssubtree was added. If you try to update a previously 

installed Metacat, you should run a script file to updated the table structure 

before installation.

For Oracle user: At the SQLPLUS prompt type the following -

@src/reviseformetacat13.sql

For Postgresql user: At install directory prompt type the following -

psql exp < src/reviseformetacat13_postgres.sql

(where 'exp' is the database name).

After installation, user should run "ant schemasql" command to register EML2

schema in xml_catalog table.

If you are a new Metacat user, this step is unneeded.

New Features in 1.3.0

  1) Partialy support EML2 document. User can store, query, read and write

     EML2 documents. However, Metacat only support access control in resource

     level. The subtree level access control will be ignored.

  2) Support other xml document base on namespace/schema.

  3) Support query for attribute value

  4) Assign MIME type to data file base on metadata when user try to read it.

  5) Owner can assign access rules to a document which does not have access 

     document to apply it.

  6) Support exporting single file, not only whole package

Fixes in 1.3.0:

  1) Couldn't finish delta T replication for large set of documents.

  2) Couldn't create access control during delta T replication.

  3) Eorr will be written to a seperated log file if some documents

     were failed in replication.

  4) Decrease the time to create access rules during insert or update 

     a package.
