There is the stub of a recipe for this at
I still have moderated hope to be able to finish the recipes within the 
next couple of weeks.

In general, the key think to keep in mind with GoodRelations is that you 
will always have three main entities

someone - e.g. the company offering something; this is a gr:BusinessEntity
something, on which a bundle of rights is offered to be transferred for 
a compensation, e.g. a ticket; this is mostly a 
a promise - the statement that the "someone" is offering to transfer a 
bundle of rights on the "something". this is the gr:Offering.

In other words, GoodRelations is all about Agent - Promise - Object 
("APO"). If you keep those three entities distinct, your are always on 
the right track.

The second key resource for anybody implementing GoodRelations is the 
UML diagram at


In your case, you will have

- an event (this is outside the scope of goodrelations)
- a ticket, that grants permission to attend a certain event

Make sure that you do not fall in the trap of mixing the event and the 
ticket ;-)
