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

Release Notes for 1.4.0:
36
------------------------
37

  
38
This is a major release, and is the first to introduce many new features to
39
Metacat.  Some of the major new features in this version of Metacat include:
40

  
41
* Added a new 'Harvester' that allows documents to be periodically pulled
42
  from distributed sources into metacat, useful for interfacing with other
43
  system types. See the Metacat Tour for details.
44
* Added new 'skins' capability to allow the GUI for the metacat web interface
45
  to be more easily customized to fit into site needs.  The skin is based on
46
  a flexible mix of XSLT, CSS, and Javascript.
47
* Added a web-based metadata entry form for submitting EML limited EML documents
48
  as part of a data registry.  The GUI for the registry is customizable and 
49
  is integrated with the 'skins' system for the main metacat interface.  The
50
  registry subsystem is written in Perl, and can simultaneously be used to 
51
  present multiple 'registry' interfaces.
52
* A new 'client API' has been developed and implemented in Java and in Perl 
53
  so that metacat functions can be accessed from any program in those
54
  languages.  The client API supports the major metacat servlet actions,
55
  including login(), logout(), query(), insert(), update(), delete(), and 
56
  upload(). See the Metacat Tour for details.
57
* Added a new 'getlog' action that produces a usage history for all major
58
  events.  So now an XML report can be generated for document reads, inserts,
59
  deletes, etc.  See the new section in the Metacat Tour.
60
* Added a new 'buildindex' action that can rebuild the index entries for any
61
  document in the database.
62
* The configuration file for metacat (metacat.properties) has been moved out
63
  of the jar file and into the WEB-INF directory, allowing far easier changes
64
  to the configuration parameters.
65
* Results in default web interface are sorted by title in the XSLT (configurable)
66
* Several significant and insignificant bugs were fixed.
