Version: 4.0 Leeloo (Release 2011-12-20)#

d3web is an extensible Java API for running knowledge-based systems. The Semantic Wiki KnowWE builds on the engine d3web and offers the web-based and distributed development of knowledge bases.

This distribution comes with the following files:

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 or 10.7. Linux is not officially supported. We officially support Firefox 7 or better and Google Chrome 14 or better. Please note, that we do not officially support Internet Explorer at the moment.

What's New#

The release includes the following notable features:

d3web#

  • New formula predicates to compute the percentage (between 0-1) of the time a specified history has been greater, equal, etc. than the specified value: percentEqual, percentGe, percentGt, percentIn, percentLe, percentLt, percentUnequal.
  • Faster reasoning due to kernel optimizations.

KnowWE#

  • denkbares Skin brings new look and feel but also enhanced usability (e.g. scroll behavior of the LeftMenu).
  • Instant edit for authoring knowledge directly in the view mode of the Wiki.
  • DiaFlux does not store the preview in the wiki article anymore, but renders the graph directly.
  • Improved display of complex formulas in DiaFlux.
  • ImageMaps to define clickable areas in image questions (supported by denkbares dialog).
  • Ability to define UNKNOWN as init value for questions.
  • Improvements to rendering and error handling while defining properties.
  • Wrapping of long object names in QuickInterview.
  • Support for state-of-the-art browsers: Google Chrome and Mozilla Firefox.
  • ShowSolutions Panel: Filter solutions to display in the panel (by explicitly defining shown solutions or by excluding solutions to show in the panel).
  • Continuous integration plugin improved and polished interface.
  • Alpha version of new continuous integration test: Unsynchronized condition question checks, whether a value of a question was conditioned and assigned without having a snapshot between.

Known Issues#

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

IDProductSeverityTitleRelease Comment
230 d3web Average problem Java Heapspace exceeded A benchmark and test environment will be set-up for testing the massive use of d3web sessions.
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.
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.
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.
146 KnowWE minor [Chrome] Arrows/guards layout issues in DiaFlux after reload This issue is only observed in rare cases. Reloading the editor should resolve it as a workaround.
138  KnowWE trivial [Internet Explorer] Rendering output lacks a lot of line breaks Currently we do not officially support the Internet Explorer in KnowWE.
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 Currently we do not officially support the Internet Explorer in KnowWE.
222  KnowWE minor TestPersistence does not handle all types of answers The persistence for d3web test cases is currently used with known question types in knowledge engineering projects. After Leeloo the persistence of test cases will undergo a major revision.
223  KnowWE Lightweight problem [MobileApplication] Language Selection doesn't work The mobile application is not part of the current distribution.
