Version: 7.0 MacGyver (Release 2013-04-26)#

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.

System Requirements#

Installation of d3web/KnowWE requires the Java Platform, Standard Edition JDK 6 or higher. For operating systems, the distribution runs with MS-Windows XP, Windows 7 and Mac OS 10.6 or higher. 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#

  • Adding old values to the TimeDB: It is now possible to add values to the TimeDB, that are old than the current time of the TimeDB.
  • Default values: Since it is now possible to add old values to the TimeDB, there can also be values older than the init values. Init values are therefore now default values that are only valid as long as there are no values set before or exactly at session start.
  • writeOn property: Die writeOn-Property erlaubt festzulegen, dass bestimmte Variablen auch dann in die TimeDB geschrieben werden, wenn sie sich selbst nicht geändert haben.
  • Terminating propagation of a Session: The propagation of a Session can now be terminated. This is useful for example in
  • CondRegex: New Condition for QuestionText allowing to used regulare expressions.

KnowWE#

  • TestCase prefixes: It is now possible to define TestCases as a prefix of other TestCases. In the player they can be run as one TestCase and also can be downloaded as one TestCase.
  • TestCasePlayer improvements:
    • Currently selected TestCases can be downloaded as SequentialTestCases in the TestCasePlayer.
    • Columns of the player can be expanded and collapsed by clicking on the header and by using the respective tools.
    • Collapsed checks no longer use multiple lines in the table, which allows for a much more compact few.
    • Improved scroll behavior while removing and adding variables to the current TestCase in the player.
    • TestCases that were triggered to run a lot of time consuming steps can now be properly aborted (red square).
  • Reimplementation of EditMode: The new implementation is much more stable and no longer interferes with JSPWiki markups.
  • Improvements to ObjectInfoPage: The ObjectInfoPage now has a new Search field allowing to quickly navigate to other terms. Also the Look&Feel was refined.
  • Loop-Detection: Loops in the reasoning of knowledge bases are now properly detected by KnowWE. If a loop occurs during execution, the execution is terminated with an appropriate message.
  • Markups for new CondRegex: It is now possible to used CondRegex in markups like %%Rule. Example: IF Question = /valueregex/ THEN...
  • Table-Plugin: Added the external JSPWiki TablePlugin to the default configuration of KnowWE (see http://www.jspwiki.org/wiki/TablePluginBenutzung for more infos)
  • Performance: Improvements for compilation of formulas. Wikis with a high amount of formulas should experience a significant acceleration of saving changes in the knowledge base.

Known Issues#

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

ID Product Severity Title Release Comment
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.
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.
223 KnowWE Lightweight problem [MobileApplication] Language Selection doesn't work The mobile application is not part of the current distribution.
348 d3web Average problem A KB can not be loaded, if the infostore of a DiaFlux model contains a property This ticket does not describe a bug concerning the usage of d3web and KnowWE, but an architectural issue restricting developers to not store properties (description, prompt...) directly with Flow objects.
451 KnowWE minor Trying to use triple curly braces in DefaultMarkups destroys these markups Workaround: Please try to avoid triple curly braces inside KnowWE markups.
