[protege-owl] Protege & DataMaster

Thanks a lot so in simple terms at the present moment there is no solution for dynamic mapping until the full development of SWRL/SQWRL?

I try to answer here both of your questions: from this e-mail, and from 
the one where you ask:
"Is there a way for me to be able to query for information from my 
database which I have imported to Protege using DataMaster?"

The answer is: this is exactly what we mean by dynamic mapping.
You can use DataMaster to import the database schema to Protege where 
tables and table columns will be represented as instances in the 
Relational.OWL ontology. Later you can use the imported schema to 
dynamically query the database.

Our solution for this problem (using 
SWRL/SQWRL) is under development and we expect to release it sometimes 
later this year.



Of course you can implement your own dynamic mapping, too, that will use 
the imported database schema to query or make reasoning on a knowledge 
base whose instances are stored in relational databases.

You can, in different ways, but DataMaster does not offer you a 
convenient way for doing this. If you try to import instances from a 
database to an already existing class structure in your ontology, maybe 
you are interested in the following thread:
http://thread.gmane.org/gmane.comp.misc.ontology.protege.general/16756

I hope this answered your questions. If not, please give us a detailed 
description of what you are trying to achieve.
