Abstract:

The TMQL canonizer is an online validation service for TMQL queries.

Today the Topic Maps Lab has released the TMQL canonizer, which is an online validation service for TMQL queries.The service uses the TMQL draft of 2008 and the tmql4j query engine version 3.1.0.

As depicted in the figure below the service returns the canonical form of a given query. Furthermore the parse tree is given. In the case the given TMQL query is not valid, the parse error is returned in details.

The TMQL canonizer is online available. Simply try the following TMQL query:

// http://psi.topicmapslab.de/inventurtool/project MINUS http://psi.topicmapslab.de/inventurtool/uses >> typed >> roles >> players

The code of the servlet is available as open source in the TMQL4J project at Google code.

UPDATE 2011-04-15: The canonizer now supports not only the 2008 draft of TMQL, but also the 2010 and 2011 draft.

I like the easy but powerful way of merging Topic Maps to extend and combine existing knowledge bases. Thus I see high potential in distributed environments where peer to peer solutions may open the gates to the real Web 3.0.
