MOKB and MMD Ontology Usage Examples

This document contains a set of MOKB query and update examples for use with the CALO ontology. Please be sure to refer to MokbGrammar for a general explanation of MOKB message syntax and functionality. Also note that it is difficult to keep this completely up to date with the regular ontology changes that are happening. Please be aware of this.

A Typical MOKB Session

Start up the agent manager
Start the following agents (note that they should be loaded in sequence, wait for each to finish before doing the next or you may run into a Jena-related bug):
- Administrator
- Update Server
- Non-reasoning Query Server
- Client GUI
If this is your first time using a new version of MOKB, or you want to start from a clean database, click INIT on the administrator
Test your updates and queries in the Client GUI
Run your algorithm
Save to file and look at the file to make sure your triples are there

Notes on MOKB client use

Be sure to leave some lag time between your last update and saving the db, sometimes OAA is still queueing updates and you last few will not have been inserted in the db before you print it
