XML document, therefore allowing storage of XML documents with arbitrary

schemas. Metacat supports several databases on the back-end, including Oracle,

PostgreSQL and SQL Server (limited).  The server supports XML document

database to other metacat instances for backup and load balancing purposes.

Metacat currently uses an LDAP database for authenticating users, but was

written to accomodate other authentication services as well.

Release Notes for 1.9.1:

------------------------

The 1.9.1 release holds the bug fixes found after releasing 1.9.0 beta.

These bugs were primarily replication issues.  There is no difference

in functionality between 1.9.0 and 1.9.1

------------------------

This release focuses on simplifying the Metacat installation process by

creating a binary (war) installation.  The need to build the application

on the server has been removed (although the option is still available).

In order to facilitate this method of installation, a few major modifications

were made to the code:

  -- Ant token replacement was removed for all non-build variables in the

     application (most of this was already done in 1.8.1).

  -- The Metacat properties confguration was moved into the application

     itself.

  -- Database schema version detection and install/upgrade utilities were

     added to the application.

Also, this release includes several enhancements:

  -- it supports the new EML 2.1.0 version.

  -- Documents are now stored on the local filesystem as well as in the

     database in order to preserve document integrity.

  -- Metacat verifies new schemas when they are added.

  -- Additional access is propegated with documents during replication.

High priority bugs were addressed in this release as well.

The enhancements/bugs addressed are:

* escaped "less than" in inlinedata causes invalid eml output (Bug 2564)

* need to set filename for download files (Bug 2566)

* add ability for search engines to index metacat documents (Bug 2826)

* EML citation section should include both organizationNames and individualNames (Bug 3059)

* refactor skins to get organization list from metacat getOrganizations() function (Bug 3114)

legitimate EML 2.0.1 schemas; second, existing invalid EML 2.0.1 documents will be

http://bugzilla.ecoinformatics.org/show_bug.cgi?id=3239

http://bugzilla.ecoinformatics.org/show_bug.cgi?id=3241

EML 2.0.1 documents from Metacat 1.8.0 or ealier verions may be rejected since Metacat 1.8.1 uses

different EML 2.0.1 schemas (see bug 3239). If this is case, Metacat administrators should notify

their counterparts to upgrade previous version Metacats to 1.8.1.

and access control queries were rewritten to execute efficiently.

To improve search performance, a query caching mechanism was introduced.

Cached queries are currently supported only for public users.

* Data registries now support uploading of data objects along with data

  packages (Bug 1982)

* Metacat Performace: Rewrite the xml_nodes queries (Bug 2155)

* Metacat Performace: Rewrite the xml_access part of the query (Bug 2557)

* Tomcat 3 and 4 are no longer tested or supported. Users are

  highly encouraged to upgrade to Tomcat 5.5

------------------------

This release features only a few minor changes to the core Metacat engine.

The major focus of this release is the addition of the spatial functionality.

The geographic coverage of metadata documents can now be cached in a GIS-

accessible format and published via web mapping services and an online

interactive map.

* Three new open source libraries have been integrated with Metacat:

  - Geoserver:  A standards-compliant web map server to publish

                geographic data to the web.

                manipulate spatial datasets.

                (http://geotools.codehaus.org/)

  - Mapbuilder: A javascript application to provide an interactive

                web map front-end to Geoserver.

                (http://docs.codehaus.org/display/MAP/Home)

* Spatial Caching/Indexing mechanism; documents with geographic

  coverages will be added to the spatial cache.

* Spatial Query action in metacat servlet.

* Interactive Web map to visualize and query the spatial

  distribution of metadata documents.

Compatibility Notices:

* Tomcat 3 and 4 are no longer tested or supported. Users are

  highly encouraged to upgrade to Tomcat 5.5

Bug Fixes:

* Metacat administrators are able to modify and delete documents

  created by other users.

------------------------

This release comes with more performance improvements, initial support for

LSIDs (Life Sciences Identifiers) and FGDC standard, more controls for

Metacat administrators and bug fixes. Below is the list of bug fixes and

performance improvements.

Bug Fixes:

* Improved the indexing algorithm. Earlier indexing failed for some documents

  randomly and used to take a lot of time to complete for others. The

  code for indexing was changed to take care of both these problems.

* Earlier, xmlns prefix was used to determine the namespace of the document.

  Now schemaLocation is used instead xmlns prefix to determine the namespace

  of the document as that is a better indicator of document type.

* INSTR was used in some SQL statements and it is not supported by Postgres.

  So SQL statements were modified so that INSTR is not used.

* Fixed bug in squery which didnt allow use of not-contains

New Features:

* Added FGDC schema and XSLT so that Metacat can handle FGDC standard

* Added support for LSID. This includes modifying the stylesheets to

  display the LSIDs, modifying the build to include a new target

  'install-ldap'.

* Added following access control levels to Metacat:

    1. Administrators - users who can do the following:

       a. Run replication

       b. Delete any document

       c. Modify any document

       d. run indexing for any document

       e. check the logs

    2. allowedUsers - User who are allowed to submit

    3. deniedUsers - Users not allowed to submit

* Added a new skin for Ecological Society of America.

* Various connections have been modified to be secure. e.g. connection between

ldaps is made secure now, replication is done over secure channels.

Performance:

* Reduced size of xml_nodes by creating a new table for holding nodes from

  deleted documents and old revisions of the documents.

* Provided a new variable in metacat.properties where more frequently searched

  for paths can be specified. Seperate indexes are created for these paths

  - so that search is faster.

------------------------

Bug Fixes:

* Modify property values of harvester registration servlets to match the

  servlet-mapping URL values in web.xml. The old values used the servlet

  class names. This worked in Tomcat 4 but seems to break in Tomcat 5 on

  Windows. The new values use the servlet-mapping URL values. This should

  work in both Tomcat 4 and Tomcat 5. (Bug 162)

* Re-implement logic to prune old log entries from the HARVEST_LOG and

  HARVEST_DETAIL_LOG tables. The old logic caused integrity constraint

  violations in the database because it tried to delete parent records from

  HARVEST_LOG prior to deleting child records from

  HARVEST_DETAIL_LOG. (Bug 162)

* In data registry, minor bugs fixed like the error page shows the link back

  to the form when error page was generated because of a document read

  request from search results page,  the successful delete button leading

  to a blank screen and the old ACL overwritten by the registry.

  (Bugs 1307, 1310, 1322, 1344, 1551)

* Changed the code to support insertion of following characters: ', `,

  charcters in the Numeric Character Reference format (&#xyz;) and
