ANN: eXist 0.4 XML DB with native and relational backend

I am pleased to announce that version 0.4 of eXist has been
released. eXist is a database and retrieval engine for XML
documents. It provides pluggable storage backends, storing XML either
in a relational database or using a native backend. eXist has it's 
own XPath implementation with fulltext support. The new version is 
available at http://exist.sourceforge.net.

Changes since version 0.3:

* new native backend which uses sequential files and btrees for the 
  indexes.

* added support for PostgreSQL as storage backend. 

* enhanced DOM to handle namespaces, comments and processing
instructions.

* entities are preserved.

* bug fixes to better support MS WIN.

Until a comparable, pure Java implementation is available, the native
backend uses the Java API to Berkeley DB for the btrees. Berkeley DB
is a well known C-Library on Unix systems and also supports MS Win.

The new backend is very fast when retrieving document content, because
all nodes are stored in document order inside a sequential file. Whole
documents or larger parts of them may be retrieved in very short
time. Loading documents into the database will be faster, too.
