[Attempto] AceWiki 0.4.0 Released

[Tobias Kuhn]

Hi everyone,

I released a new version of AceWiki: 0.4.0. It can be downloaded on 
Launchpad:

   https://launchpad.net/acewiki

See the AceWiki page for the public demo instances:

   http://attempto.ifi.uzh.ch/acewiki/

This release contains major updates on the reasoner integration. Most 
importantly, the reasoner is now exchangeable and external reasoners can 
be connected. The default reasoner is no longer Pellet, but HermiT. 
Version 3 of the OWL API is now used, instead of version 2. New 
parameters are available when launching an AceWiki instance. Several 
parts of the user interface, including the predictive editor, have been 
improved. Furthermore, there is a new export option to download the wiki 
content as two CSV lists. Additionally, there has been general code 
refactoring and clean-up. See the change log below for more details.

Cheers,
Tobias




Change Log AceWiki 0.4.0:

- Moved from version 2 to version 3 of the OWL API.
- Moved from OWL 1.1 to OWL 2.
- HermiT is used instead of Pellet as default reasoner (because of 
license reasons). Pellet is
   still supported but is not part of the AceWiki package anymore.
- Support for OWLlink added. In this way, other reasoners like FaCT++ or 
RacerPro can be used.
- New web.xml parameters:
   - owl_profile: restricts the reasoning on statements that are part of 
a certain OWL profile.
   - global_restrictions_policy: defines how the global restrictions of 
OWL 2 should be enforced.
   - readonly: allows for launching an AceWiki instance that cannot make 
changes on the ontology.
   - possible_answers: an experimental feature that enables to show 
possible answers, i.e.
     individuals that cannot be proven not to be an answer.
- Sentences can now be manually retracted from reasoning without being 
removed from the wiki.
- Sentences that do not participate in reasoning are now consistently 
displayed in red font.
   Before, this was only the case for sentences that violated at some 
point the consistency of the
   knowledge base.
- Improved dropdown menus:
   - Tooltips for the menu entries.
   - Reordering of the menu entries.
- A new "About" page has been added with information about the given 
wiki instance.
- The predictive editor has been improved:
   - Improved calculation of the content of the menu blocks.
   - Better implementation of the asynchronous menu creation.
- Refactoring of the ontology classes of AceWiki.
- New export feature for AceWiki: The wiki content can now be downloaded 
as two CSV lists (one
   containing the entities and another one containing the statements).
- Unix shell script added to run the web applications with Jetty Runner.
- Simple progress bar on the standard error channel when an AceWiki 
ontology is being loaded.
