From NeOn Wiki

NTK 2.4.1 is based on the OWL API 3.0.0, which was released in January 2010.

The latest build is uploaded Feb 14 2011.


We appreciate any feedback, e.g. via our Issue tracking system (Bugzilla) or via emails to the developer-mailinglist.

To download and install additional features, start the NTK and go to Help > Install new Software. Select the NeOn Toolkit Update Site (for more details how to get the NeOn Toolkit Update Site, see the Welcome page Help > Welcome), select the plugins you would like to install, and finally accept the license terms. The selected plugins will now be downloaded and installed.

We are maintaining a list of all known and NTK 2.4.1 specific issues.

What's new in the NeOn toolkit 2.4.1:

Bug Fix:

  • User Interface did not display search results

What's new in the NeOn toolkit 2.4:

Search result:

  • Search results represented as tree
    • tree structure: project – ontology – entity/axiom
  • Axioms in search results presentated in Manchester Syntax
  • Jump behaviour for search results, especially for axioms, are changed
    • e.g.: Class: class1 SubClassOf: class2 --> taxonomy tab of class1

Editing functionallity of axioms of imported ontologies:

  • Grayed edit button without functional --> edit* button
    • allows you to edit axioms of imported ontologies
  • Grayed remove button without functional --> remove* button
    • allows you to remove axioms of imported ontologies

New views:

  • Range View
    • similar to the Domain View
    • shows all properties that have the selected class or data type as its object
  • Property Members
    • similar to the Individual View
    • shows all relations, i.e. subject and object or value, of the property which is selected in the Navigator
  • Created help content for new views

KC-Viz - Key Concepts Visializer:

  • KC-Viz is part of the NeOn Toolkit "Core" and no longer a NeOn plugin
  • Aggregated context menu for visualizers (KV-Viz and Ontovisualizer)

Menu:

  • Reduced menu items
    • removed items inherited from eclipse which are not used or doesn't have a functionality in the NeOn Toolkit

Other new features:

  • Type of properties will be auto-completed when entering the properties based on the range of the property
  • Display of the currently used ontology in the EPV
    • optional: Can be set in the preferences
  • Class restrictions are removed from the Taxonomy view, because they are already displayed in the Class Restrictions view
    • optional: They can be displayed again by changing the settings in the preferences
  • Changes the view, only if it is a new object selected, so the empty page is not shown that often anymore

Bug Fixes:

  • CRTL-jump in combination with Display Style "local"
    • jumps to the entity if it can be clearly identified
    • change the Display Style to QNAME, in case it can't be clearly identified
  • Labels of restriction quantifiers changed to Manchaster Syntax
  • "Find References" does not work for annotation properties FIXED
