Wikicompany:Semantical interface extension
From Wikicompany

Introduction
(todo)
Wikicompany is now able to use semantical annotations (relation links, and attributes).
See some examples of articles with semantic annotations:
OWL
OWL ("Web Ontology Language") at W3C.
http://www.wikicompany.org/sw/2006/01/wikicompany.owl
Semantical Searching
This functional part isn't ready yet, but you already use the simple semantical search interface.
The plan is to create both a fancy semantical web search form, and integrate some of the semantical functionality with the (yet to be written) REST web API.
How to write the semantical annotiations
The idea is to use Categories as property tags, and then to give these tags relational meaning through a semantical annotion.
Relation labels:
- company
- This label just points to the company name, but should actually be an attribute. However that doesn't work with Category linking (yet).
- in region
- in sector
- has parent
- has subsidiariary
- has affiliate
- has partner
- has comptetitor
Attribute labels:
- of type
- founding year
- current CEO
