Delay longer than expected

We are a bit behind the schedule, but we will release the new build shortly. Sorry for the inconvenience ;)

Release delayed one week

We will have a small delay on the release that's scheduled for this week. We will postpone it until next week to be able to clean some last minute issues. Stay tuned! this release is packed with goodies, including Protege 4.2 support, support for LIMIT, OFFSET, ORDER BY and many other things!

v1.7-alpha-b1529 is now available

A new build for v1.7-alpha is now available. This time we focused on improving user interaction and solving important bugs/issues related to stability and we are happy to say that this is our most stable and user-friendly build to the date.

Highlights of this new build include:

• Improved error reporting and error message in Quest
• Improved syntax error reporting and messages in the mapping editor of -ontopPro-
• Fixed critical stability issue that triggered an endless loop of error dialogs in Protege 4.1
• Better layout, improved fonts and other GUI enhancements.

For a detailed description see our changelog.

As a hint to whats coming on the next release:

• Quest support for LIMIT, OFFSET and ORDER BY in SPARQL queries.
• Extending FILTER functions
• First release of the QuestOWL and -ontop- for OWL, the OWLAPI 3 libraries that will allow you to use Quest and -ontop- directly from Java, using the OWLAPI 3.

OWLED and ESWC invitation

Next week, during OWLED, we will have a presentation about Quest. After that I'll stay for ESWC. This would be a great opportunity to meet people interested in OBDA and -ontop-, to have discussion and/or hands-on sessions. Please contact me if you would be interested in something like that, we can arrange some time during the conferences.

Stay tuned!

Build 1446 now available

Build 1446 for v1.7-alpha is now available. This build fixes a small bug where mappings that introduce concrete individuals would not be rendered properly by -ontopPro-. The kind of problematic mapping would be:

<"&:;people/{$id}"> :knows <http://physics/Stephen_Hawking>

SELECT id FROM physicists

The problem would rise when there is no prefix for any fragment of <http://example/physics/Stephen_Hawking>

We also added coloring for individuals in mappings.
