System Requirements#

Installation of d3web/KnowWE requires the Java Platform, Standard Edition JDK 6 Update 21 or better. For operating systems, the distribution runs with MS-Windows XP, Windows 7 and Mac OS 10.6. Linux is not officially supported. We officially support Firefox 3.6 or better but most parts are also working with Google Chrome. Please note, that we do not officially support Internet Explorer at the moment.

What's New#

The release includes the following notable features:

d3web#

  • Faster reasoning due to refactoring of the blackboard architecture.
  • DiaFlux: Improved version of the DiaFlux problem-solver.
  • Improvement of test coverage and code analysis results.
  • Small API changes for a better access to the terminology and the problem-solving knowledge.
  • New API for test case analysis of problem-solving sessions (see EmpiricalTesting).

KnowWE#

  • KnowledgeBase tag: Names of downloaded knowledge base can be specified in advance.
  • ShowSolutions tag: Restrict presented abstractions and define the number of digits for displayed numerical questions.
  • ObjectInfo: You can click on the definition of terminology objects in order to open an object info page: Here references, definitions, and further information of this object is shown.
  • DiaFlux: Much improved editor for creating and editing DiaFlux models, better editing possibilities and new icons. A renderer highlights the current flow in the view mode of the article, when a problem-solving session is executed.
  • Continuous integration (still beta): New CI damon designed for placement in left menu. Some extensions of tests.

Known Issues#

The IDs of the listed issues correspond to the ticket tracking system available at https://tickets.denkbares.com.

IDProductSeverityTitleRelease Comment
104  KnowWE Average problem Malicious HTML code in wiki pages/requests For relevant KnowWE applications we recommend to secure the wiki server by htaccess controls and to provide user authentication.
132  KnowWE Average problem KnowWE / d3web session identifies the users by their IP adresses This issue may be a problem when users behind a proxy use KnowWE.
117  KnowWE Lightweight problem URIDecoding of request parameters is done twice: once by Tomcat and once in KnowWEParameterMap For the currently deployed plugins this issue is resolved by workarounds. In further releases this problem should be fixed in a fundamental manner.
141  KnowWE minor Wrong resolution of case-sensitive article names At the moment users should be aware of the case-sensitiveness when opening articles by entering the URL directly in the browser.
142  KnowWE minor Packages and articles cannot share the same name Workaround: Simply choose a package name that you do not need to use as a name for an article.
146  KnowWE minor [Chrome] Arrows/guards layout issues in DiaFlux after reload Chrome is not officially supported in Q. Furthermore, the issue is almost non-existent in many cases.
152  KnowWE minor Deleting attachments of an article can yield broken page view This is still an open issue with JSPWiki. Workaround: In the rare cases you have to delete the attachment folder in the respective wikicontent directory on your server. Sometimes restarting KnowWE also helps.
215  KnowWE minor [Chrome] Erroneous rendering of "My prefs" button in Chrome This problem does not affect the functional part of the knowledge engineering task.
108  KnowWE minor Page rename yields compile errors when the renamed page defines the knowledge base Workaround: In these rare cases simply restart KnowWE.
81  KnowWE minor ReRenderSectionMarkerRenderer should support "external" wiki pages For the Q release no primary plugins are affected by this issue.
212  KnowWE trivial [DiaFlux] Start and Exit nodes do not allow certain special characters Workaround: Please try to avoid special characters for names of Start/Exit nodes until the bugfix.
213  KnowWE trivial [Internet Explorer] DiaFlux edit panel does not work with IE9 We do not officially support the Internet Explorer for the release Q.
136  KnowWE trivial [Internet Explorer] DefaultMarkup-ToolMenu is "shifted" We do not officially support the Internet Explorer for the release Q.
138  KnowWE trivial [Internet Explorer] Rendering output lacks a lot of line breaks We do not officially support the Internet Explorer for the release Q.
161  KnowWE trivial KnowWE startup causes 'INVALID SECTIONIZING' exception This warning does not affect the expected knowledge engineering behavior.
177  KnowWE trivial Semantic Annotation Markup renders error "intermediateOWLObject not found" in any case In current knowledge base development, the semantic extensions are not used.
197  KnowWE trivial "Same TermDefinition"-warnings at KnowWE startup This warning does not affect the correct behavior of the knowledge engineering task.
193  KnowWE trivial "New" buttons are not syned in QuickI and denkbares Dialog Workaround: When using both dialog interfaces and when trying to clear the current session, then please use the "New" button of the denkbares dialog.
