wiki:Brainstorm_patch_for_eXe_and_objective_ontologies

This is a place for organising the ideas, thoughts and useful links arising from an initial brainstorm in the eXe forums. This represents the second phase for developing a use case on "objective" ontologies. Our final objective is to generate a range of use cases for future development of eXe. There are guidelines for developing eXe use cases. You can also have a look at the following examples to see what the product will look like:

We follow the open traditions associated with wikis, and at any time you are free to draft a paragraph for the parent use case. Don't worry, if the eXe community refine your ideas - they will <smile>.

You are free to alter, change and adapt this wiki page as the project progresses. Have fun.

Magpie - the Semantic Filter - http://kmi.open.ac.uk/projects/magpie/main.html : There's a plugin for Firefox available, not quite an extension (you have to unzip and install thru a readme) but perhaps worth a look.

Graphical representations, concept maps

  • We must find intuitive ways for users to select and view ontologies. Click on example under demo on this French site.
  • More information on conceptual graphs or topic maps on google
  • A free to use topic mapping tool: cMapTools
  • Automated Tree-drawing, a solution for a xlst to tree view conversion
  • A current and popular way to display 'tags/folksonomies' is with a tagcloud: see my del.icio.us tags for an example: http://del.icio.us/simp. scroll down past all my tags and select "view as cloud" or see the front page of http://www.43things.com/
  • Drupla.org is a CMS that lets you very easily organize your content according to complex taxonomies. Open source, PHP, MySQL, it combines the advantages of folksonomies with one word tagging and size-dependent tag formating with the advantages of a complex ontology, with the possibility to structure nodes within a tree, with eventually multiple node-parent relationships, synonyms declaration, or associations between nodes of independently defined tree being defined. You will find a working demo at http://widged.com/etivities/?q=taxonomy_dhtml with a taxonomy that lists dewey main divisions and many of LOM limited vocabularies within a tree-organization. If a freemind module is installed, the taxonomy defined for navigating the cms can be converted into a topic map representation, as illustrated at http://widged.com/freemind/education_taxonomies.html, thanks to either a flash or a java applet. Links can be added to any node to point to either local or remote document. With the flash applet, a search box can be made available to search the tree content. On top of the flash and java applets, the freemind project provides a standalone application for the editing of the topic maps, available for most platforms. Freemind is an opensource project advertised on sourceforge http://freemind.sourceforge.net/wiki/.
