Re: Inferred graph vocabulary?

Hi Andrew,

It was Rinke Hoekstra who said at the right time 20.10.2009 11:20 the
following words:

As said, this was done in NRL partly, adding one or two properties to
NRL does cover it.
please read NRL and express your additions as a ticket and send it to
oscaf.sourceforge.net,
so that it can get into the implementations.

fyi:
NRL has some wide distribution, an active community with maintiners, a
guarantee to be there the next years with an organisation to back it
(www.oscaf.org), and developers implementing it because they implement
NIE. Its part of nepomuk.kde.org, which is in deployed use on many
desktop pcs in the world. (and will probably be on nokia's maemo platform).

... so there are other people already working on it, you don't have to
start anything new and build your own legal body to own the domain where
you host the ontology for a longer time (if you want, oscaf did that for
you).

this is the decision making process of these ontologies:
https://sourceforge.net/apps/trac/oscaf/wiki/OntologyMaintenance#NRLandNAOMaintenance

an overview of the pending changes to other ontologies:
https://sourceforge.net/apps/trac/oscaf/report/1

The extension you mention is needed for NRL, we are waiting for the
input anyway.

As documented there, the maintainer is Simon Scerri from DERI. I added
him CC.

Of course, doing it properly and documented and tested like this does
take a lot longer, but your input will stay once you have left doing
other things. If you prefer a quick hack you have to maintain yourself,
ignore my mail and do so, I won't bug this topic again in this thread :-)

best
Leo

Andrew, I would suggest to define the extensions you need to NRL and
submit them as a ticket
