SS v2.3

We have just released v2.3 of Semantic Search for DSpace. This is mostly a maintenance and compatibility release that adjusts Semantic Search for v3.x of DSpace:

• Provide a new qdc.xsl that allows full export of internal DSpace metadata to dcterms including bitstream metadata, types and language tags. This file replaces the default and its effects can be seen through the standard OAI interface.
•  Output semantic query time to the front-end (just like in traditional search).
• various pom files fixes and configurations.

You can download the new version directly from git (tag SSv2.3) or you can apply this patch as per the updated instructions.

Attention: for changes to take effect you need to clean the OAI cache first:

[dspace/bin]>./dspace oai clean-cache

SS v2.2 is out!

This is to announce the release of Semantic Search v2.2 for DSpace. This release is compatible up to DSpace 1.8.2 and includes mostly bug fixes and improvements in the ontology construction. What's new:

• Better exception handling/bug fixes: Avoid “Internal System Error” when ontology URL cannot load
• Added recent history for ontology URLs in Options
• Improved support for queries with the DateTime datatype. E.g. to find items accepted after 1-1-2011:  dcterms:available some xsd:dateTime[>"2011-01-01T00:00:00Z"^^xsd:dateTime]
• Linked Data: Instead of URNs, the XSLT now assigns resolvable identifiers to items and collections (handles, if available)

Moreover:

• Added three video tutorials under Documentation
• Bundled changelog
• Added ontology files under git control (here)
• Set up a version independent demo URL: http://swig.hpclab.ceid.upatras.gr/dspace-ss-demo The demo has been also updated to Semantic Search v2.2.

You can download the new version directly from git (tag SSv2.2) or you can apply this patch as per the updated instructions.

In the meantime, we are working on providing a stable version compatible with the latest DSpace v3.1. Stay tuned!

Git migration complete

We have just completed the migration of source code versioning to git. The latest development version can now be accessed as:

git clone https://code.google.com/p/dspace-semantic-search/ or https://dspace-semantic-search.cooglecode.com/git


Further development will commence from there from revision r268 onwards.
The (old) svn repository will still be available at:

https://dspace-semantic-search.googlecode.com/svn/


Documentation images and ontology files have also been moved to their own git repository:

http://images.dspace-semantic-search.googlecode.com/git/
http://ontologies.dspace-semantic-search.googlecode.com/git/


so you might want to update your links. 

Migration to Git

Soon we are going to switch code versioning of DSpace Semantic Search at Google Code to git in order to align with the main development stream of DSpace and support decentralized development.
Previous patches will still be available in the downloads section. A snapshot of the svn repository at the time of migration will still be available (http://dspace-semantic-search.googlecode.com/svn/) but will no longer be maintained.

New video tutorials

Two more video tutorials have just been released. These are: Part 2 of 3: Results and the Navigation Pane & Part 3 of 3: Options.
