Metacat

Version: 1.2.0 Release

  1) If dataset document has a triple that access document provide

     access control for itself, the xml_access table wouldn't have double

     entries for access document.

  2) Fixed the bug for spatial search when there are letters in latitude or

     longitude nodes.

For 1.2.0:

In 1.2.0 release, the structure of the xml_replication table was changed.

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/xmlreplicationtable.sql

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

psql exp < src/xmlreplicationtable_postgres.sql

(where 'exp' is the database name).

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

The build.xml file now has a property named datafilepath. It should be set

to the location of where you want your data files stored. The data directory 

needs to be writeable by whatever user is running tomcat. If you are an

existing user, the data directory is now /<tomcatdir>/webapps/metacat/data

where <tomcatdir> is the your tomcat installation directory where

your webapps directory is located and 'metacat' is the name of your servlet

instance. If you leave your data directory where it currently is, your 

data files are web accessible.  If you do not want your data files to be 

web accessible, move the data directory somewhere outside of your 

webapps directory and change the datafilepath property in the

build.xml file and reinstall metacat.  Note that if you have existing data

files, they need to be moved to the new directory.  For more information 

see bug 478.

  New features in 1.1.0:

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

     all of the data and metadata as well as a rendered html summary of

     the metadata.

  2) Changed version control mechanism.  Metacat can now accept any version of

     a document as long as the given version number is greater than the

     current one.  The new version number does not have to be exactly one

     greater than the current version.

  3) Update xerces.jar file to version 1.4.4

  Fixes in 1.1.0

   1) Fixed ldap authentication bug.  Now, a user from a referred server cannot

      login with an incorrect password.

   2) Changed the default behavior of the access control functionality with

      respect to packaging.

      If a member document in a data package doesn't have an access control list,

      access control rules of the main package document will not apply to the

      member document.  Previously, package members, by default, inherited

      the access control rules of the main package document.

   3) Fixed minor bugs with document access control.

   4) Allowed new version of data files to be uploaded and handled.

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

      the ldap server.

  Fixes in 1.0.3

   1) Fixed problem with Metacat not being able to query for group names when

      and LDAP referral server was down.  Added an LDAP timeout of 5 seconds

      for all referral activity.

   2) Fixed problem where invalid xml characters such as ampersands (&) could

      be inserted into the resultset xml stream.

  Fixes in 1.0.2

   1) Fixed problem with LDAP locking up Metacat when a referral server

      was not available.

  Fixes in 1.0.1

   1) Fixed problem with authenticating using LDAP referrals

   2) Fixed bug that prevent groups from being used in access documents
