Hi there,

I have AllegroGraph (AG) installed on a Macbook Pro (Snow Leopard) and Im using the HTTP interface (the new-http-* version) with ruby to interact with the triple store. I also have AgWebView running to give a web view of the store. If I run a sparql query using AgWebView I can explicitly turn on inferencing and life is good, however, if I run the same sparql query via the http api there is no inferencing going on, presumably because its not turned on by default for that method.

Does anyone know how I might configure an AG triple store to have inferencing turned on so that it would work via the HTTP API, or how I could ask the store to use inferencing for a given query by passing in some parameter in the HTTP call?

Cheers!

Simon.

Yes you are right in saying that Inferencing is not turned on for the HTTP API by default.

There's a boolean infer parameter that you can add as one of the parameters of your request - this is from the documentation:

	Hi Rob, Clearly I am guilty of not following rule number one: RTFM. That was exactly what I was looking for and solves the issue, many thanks! – Simon Twigger Jan 21 at 14:54
	I had a lot of issues getting started with AllegroGraph because their manuals are a bit iffy so I wouldn't feel bad about not spotting it - I had an issue with configuring it which I eventually found the right manual page for but not for several hours! – Rob Vesse Jan 21 at 15:35
