[Tracker] Procedure to change Tracker Ontologies in Running System

["Compton, Matthew" <matthew compton windriver com>]

Hello,

I'm wondering if it is possible to change the Tracker ontology in
running system that already contains data.  I think the only needed
changes are to add classes or properties to classes.  Also, I'm hoping
to avoid having to re-index everything that is already stored in
Tracker.

> From the page
http://live.gnome.org/Tracker/Documentation/SupportedOntologyChanges it
looks like it is possible to update the ontology on a running system,
but I don't see anywhere (in code documentation or the online
documentation) if there is a specific procedure for doing this.  From
the code it looks you can:
1. Shutdown Tracker
2. Update the ontology files
3. Restart tracker and I think it will update the database to match

I'm going to test this today but I thought I'd ask the experts if there
are any things to watch out for and if there is an official procedure
for doing this.

Thanks for the help,

Matt
