2012-01-19: DeepaMehta 4.0.7

The main feature of this release is the compatibility with the "DM4 Kiezatlas 2.0" plugin and the attendant plugin development framework extensions. Furthermore there are some general GUI improvements and bug fixes.

Compatibility with 1 new plugin (optional install):

Compatibility with 2 updated plugins (optional install):

GUI improvements:

  • Auto-positioned topics appear near selection. This results in less mouse drags and less canvas clutter (#174).
  • New icon for "search result" that replaces the bucket: a pile of balls [69aa3fd4].

Bug fixes:

  • The topicmap state (translation) is persistent after auto scroll (#170).
  • Deleted associations resulting from combobox value changes are removed from the canvas (#176).

Plugin development framework:

  • Webclient performance improvement through new hook mechanism: hook code is explicitly registered at the webclient (instead of placed in dedicated methods) (#173).
  • Customizable GUI:
    • Decouple canvas from page panel: the topic selected on the canvas and the topic displayed on the page panel can be a different one [ce27623b][ac819a9a].
    • Customizable page panel rendering in case of nothing is selected (new hook default_page_rendering). Splash screen by default. [40cb0f8f].
    • The default page renderer and form generator are customizable (new hook pre_render_page) [69866e36][bb7cc70b][af4f2ff9].
  • More flexible update requests: plugins can attach application-specific data to update requests and provide the corresponding server-side processing logic [b54822fc].
  • More convenient client-side API for accessing (nested) topic values [616e35d6].
  • Cleaner exception logs from REST resource methods [ebd02479].

Improvements for plugin developers:

  • Server-side plugins can extend a topic before it is send to the client (new postFetchTopicHook) [874271b8].

  • Client-side plugins can set/get the split panel's slider position (#148).

GUI improvements:

  • Topicmaps remember their translation (#154).
  • Design: the toolbar is more plain and saves screen space.
  • Design: the entire GUI uses an uniform font.

GUI fix:

2011-07-20: DeepaMehta 4.0 RC1

This is the first release with the all-new property-less data model as recently described:
​https://groups.google.com/group/deepamehta3/browse_thread/thread/a77704d35e7af539>

The version planned as "DeepaMehta 3 v0.5" now become "DeepaMehta 4.0".
From now on DeepaMehta's version numbers follow the classic major.minor.bugfix schema.

Improvements for users:

  • new type editor. All values are represented as reusable semantics-attached topics.
  • new topic type "Resource" to collect web resources
  • new icons
  • bug fix in topicmap handling (when you have multiple topicmaps open)
  • cleaner display, less clutter

The cleaner display is because not all the plugins (workspaces, time, access control, ...) are adapted to the new data model so far. So, for the moment there is not so much meta data displayed (timestamps, workspaces assignments, creator, modifier, ...).

Improvement for developers:

  • New core service API. All the domain objects (Topic, Association, ...) are attached to the database. So, the developer must not care about DB-updates.
  • Domain models (type definitions) provided by a plugin can be build upon the domain models provided by other plugins. The dependencies are handled by the framework.

Download the release:
​https://github.com/downloads/jri/deepamehta/deepamehta-4.0.RC1.zip Start as usual via the provided startscripts.

Build from Source:
​https://github.com/jri/deepamehta/wiki/Build-From-Source

For further information see the README:
​https://github.com/jri/deepamehta#readme

Troubleshooting:
If the browser shows 404 while this exception appears in the terminal ...
com.sun.jersey.api.container.ContainerException: No WebApplication provider is present
... then refresh the HTTP Jetty Bundle by typing "refresh 1" in the terminal (checkout the proper bundle ID before by using the "lb" command).

Thanks go to Jürgen and Danny who helped to organize this release!
