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 sturcture of xml_replication table was changed. If you try
|
| 36 |
|
|
to update a installed Metacat, you should run a script file to updated the table
|
| 37 |
1310
|
tao
|
structure before installation.
|
| 38 |
|
|
For Oracle user: At the SQLPLUS prompt type the following -
|
| 39 |
1308
|
tao
|
@src/xmlreplicationtable.sql
|
| 40 |
1310
|
tao
|
For Postgresql user: At install directory prompt type the following -
|
| 41 |
|
|
psql exp < src/xmlreplicationtable_postgres.sql
|
| 42 |
|
|
(exp is the database name).
|
| 43 |

|
|
If you a new Metacat user, don't need to do it.
|
| 45 |
|
|
|
| 46 |
|
|
Moreover, in build.xml it has a peroperty named datafilepath. It should be set
|
| 47 |
|
|
as same as your current data file path for person who already installed Metacat
|
| 48 |
|
|
before.

|
1) Added functionality to export a zipped data package. The zip file contains
|
| 74 |

|
| 75 |
|
|
the metadata.
|
| 76 |
1003
|
berkley
|
2) Changed version control mechanism. Metacat can now accept any version of
|
| 77 |
982
|
berkley
|
a document as long as the given version number is greater than the
|
| 78 |
|
|
current one. The new version number does not have to be exactly one
|
| 79 |
|
|
greater than the current version.

Fixes in 1.1.0

|
1) Fixed ldap authentication bug. Now, a user from a referred server cannot
|
| 83 |
|
|
login with an incorrect password.
|
| 84 |
|
|
2) Changed the default behavior of the access control functionality with
|
| 85 |
|
|
respect to packaging.
|
| 86 |
|
|
If a member document in a data package doesn't have an access control list,
|
| 87 |
983
|
tao
|
access control rules of the main package document will not apply to the
|
| 88 |
1003
|
berkley
|
member document. Previously, package members, by default, inherited
|
| 89 |
|
|
the access control rules of the main package document.
|
| 90 |
982
|
berkley
|
3) Fixed minor bugs with document access control.
|
| 91 |
|
|
4) Allowed new version of data files to be uploaded and handled.
|
| 92 |

|
5) Fixed bug where the client could not get the principals or groups from
|

|
| 95 |
|

and LDAP referral server was down. Added an LDAP timeout of 5 seconds
|
| 97 |
|
|
for all referral activity.
|
| 98 |
|
|
2) Fixed problem where invalid xml characters such as ampersands (&) could
|
| 99 |
|
|
be inserted into the resultset xml stream.
