Welcome to DenkWerkZeug

Introduction

DenkWerkZeug (DWZ) is a single-user, desktop tool to manage networked knowledge. It combines concepts of a personal wiki, a database and ideas from mind-mapping and concept-mapping.

DenkWerkZeug was developed to

  • Help you to tame complexity and
  • Create complex mental models with ease.
With DenkWerkZeug you can
  • Collect a number of facts and connections – DenkWerkZeug helps you to connect the dots and see the bigger picture
  • Enter knowledge like you think – a new item here, a longer text there, a connection between two items, in any order you like
  • Explore your model from many perspectives
  • Stay flexible – create any kind of relation or item type as you want
  • do computer-assisted thinking with the help of a rule-base inference engine

Features

Create new relations types just by using them. Powerfull auto-completion.


You can attach a note to every item. Using wiki syntax is the fastest way to connect items.


All text, including the content of notes, is indexed.


Shows you all links using this relation


Fast auto-completion helps you to re-use your existing items, relation types and property names.


Every item is like a mini-database and contains key-value pairs.


Pricing

We are currently in our private beta phase. The beta version is offered at no cost in exchange for statistical information. The software records how many items are created and which functions of the app are used. This data is sent to Google Analytics to help us improve the app. The wiki text content of items is not sent anywhere.

We plan to release a commercial version of DenkWerkZeug with even more features. We will offer discounts for students, teachers, and our beta users.

Privacy & Reliability

The software runs locally on your own Windows, Mac or Linux computer. Data is stored on your local hard drive only. The user interface runs in your browser, loading data from a mini web server built into DWZ, from your hard drive.

Each knowledge file is stored as single XML text file in the KGIF format (specification). This allows you to retrieve your data even if you stop using DenkWerkZeug. Do you wish for a particular export format from DenkWerkZeug to your other tool? Tell us

Release Notes / Version History

  • V 1.6.3, released on 2015-11-11
    Small visual bug fix.
    = File
      = Versions: CSS was showing white on white, fixed.      
    
  • V 1.6.2, released on 2015-11-10
    Computer Assisted Thinking robust. Wiki text and auto-links better.
    On stage (what you can notice):
    = Wiki Syntax: 
      + MathJAX config now same as on mathoverflow.net
      ~ Fix: Auto-Linking. This causes also less calls to Computer Assisted Thinking
        (only noticeable on large models)
      + Added auto-link updating when creating or renaming items.
        E.g. you create page "Hello" and instantly have links from all 18 pages 
        containing the word 'Hello' to the new page.
        Note this might create sometimes too many links, e.g. link "Hello World" to "Hello"
        even if there is also a "Hello World" page.  
    = File
      = Export: Fixed export file naming -- Thanks for reporting, Konrad V. 
      = Versions: List now ca. 3-4 times as fast
    
    Behind the scenes (what you cannot see):
    = Computer Assisted Thinking (CAT)
      ~ Refactored: now simpler, faster, uses ca. 30% less memory, robust.
    = Internal
      ~ Index management improved       
    
  • V 1.6.1, released on 2015-10-12
    Minor service release.
    Behind the scenes (what you cannot easily see):
    = File
      ~ Minor overall speed-ups
      = Import: Better handling of old KGIF formats
    = Minor bug fix related to auto-links
    
  • V 1.6.0, released on 2015-10-11
    Better graph. MathJAX. Naming. Computer Assisted Thinking robust.
    On stage (what you can notice):
    = All Items: Now sorted alphabetically, ignoring casing.
    = Visual Graph:
      + Showing dotted lines into the void to show where the graph continues.But never show more than 9, to avoid dramatic slow-down.
      + Better choice of node patterns used for automatic captions  
    = Wiki Syntax:
      + For the Mathematician in you: MathJAX is now enabled. All content between two dollars is type-set as a formula.
        Try "$$f(x)=x^2$$" in the note of an item.
    = Overall: 
      = DWZ uses less memory.    
      = Finished naming concept: Multiple items can have the same name. A disambiguation page appears.
    
    Behind the scenes (what you cannot easily see):
    = File
      = Open: Fix sorting "Unanamed-9" before "Unnamed-20"
    = Visual Graph: Pre-processing completely re-written.
    = Computer Assisted Thinking
      = Rewritten and simplified. Now correct, but slower. Will become faster than before -- in a later release.
      - Bugfix: CDS axiom (hasRelated, isSubTypeOf, type_symmetricRelation) => (typeRelation, isSubTypeOf, type_symmetricRelation)
    = Other
      + Handle items without content better (They can appear when importing other formats)
      + Internal index handling rewritten
    
  • V 1.5.7, released on 2015-08-20
    On stage (what you can notice):
    = File 
      = Versions: Show changes by default grouped in days (was minutes before, resulting in a loooong list)
      = Import > RDF: Blank nodes are now rendered as "_" in the graph instead of showing their ugly labels
    = AutoComplete: Improved search order of results
    
    Behind the scenes (what you cannot easily see):
    + Improved testability of code base
    + Improved consistent usage of entity metadata time stamps (created and last modified dates)
    + When sorting strings, sort casing now as "Aaa, aaa, Bbb, bbb" was "Aaa Bbb aaa bbb" before.
    + Lock files: Better detection if lock was created by same user on same machine, even if config file got deleted in between
    + Improved implementation and consistent usage of Ids
    + Bugfix for text queries with more than one term (used in AutoCompletion and FullTextSearch)

      = Show less nodes by default

      = Export: Fixed -- Thanks Nathan B. for reporting    
    = Item Rendering
      - Stop using different font sizes to distinguish items with no text, a lot of text, no links, many links, etc.
      + Use icons everywhere to display the above flags  
    = Semantic Panel:
      = AutoComplete: 
        = Fix small bug for auto-focusing object field when an existing relation was chosen

    On stage (what you can notice):
    = Wiki Syntax:
      = External link handling changed: Now by default, URLs and email addresses don't create items. They do, when put in 
        square braces. This change makes opening many external links much quicker.
      = CamelCase: Reduced strings considered CamelCase. Now all CamelCase links must start with an uppercase character.
        They may contain numbers and underscore, but not too many of them. Note you can always use square braces to force a link.
      = Auto-Linking 
        - If a wiki name is UPPERCASE; auto link from text only if text is also UPPERCASE
        + Updated internal list of known top-level domain names from official IANA list. Now www.bla.foo becomes a link and

  • Version 1.1.3, released on 2015-01-06
    On stage (what you can notice):
    + Introducing a new storage format, KGIF, the knowledge graph interchange format.
      This will allow to import/export more formats easily. All DWZ content is natively
      stored in KGIF, an XML-based format. 
      Specification documented as it evolves at 
      https://docs.google.com/document/d/1MRvF7Ko_OqRfbAGMSqiNPeZASJ_SMlMZhwR2DbqhAw8/edit#heading=h.ld5wklg5d44c
      Link to GitHub project for KGIF is also there.
    - Stopped saving content as "one text file per item"  
    + Improved rendering related items in right-side semantics panel. Redundancy removed!
    - Hide properties from graph view
    + Delete items. Some items are built-in and cannot be deleted, so this feature is safe to use. 
    + Create items without clicking "search" first  
    + Edit and delete properties in table query
    + Table query always sorts entries by content (in each cell)
    = Editing property values now remains on active view (was always navigating to item before)

    = Changed the way names are processed - now indexing more parts 
      => improved search for items that contain punctuation characters in their name
    = Fix deleting a property also deletes the property-value-item 
    = Fix CDS semantics: set transitive relation to correct relations;
      Added an inference rule for dealing with inverse-subType-inverse structures
    - No longer add item ids to full-text index. Ids are too technical.
    
    Behind the scenes (what you cannot see):
