[dotNetRDF-Support] Leviathan - SPARQL grammar extensions

[Dennis L. <Den...@St...>]

Hi,I try to find out, if it's possible to extend SPARQL grammar used in your Leviathan engine. I want to add an preference modifier to the SPARQL grammar, like proposed by Siberski et al. (W. Siberski, J. Z. Pan, U. Thaden: Querying the Semantic Web with Preferences. In Proc. of the 5th Int. Semantic Web Conf., 2006).


As far as I know there are no API's for such extensions in dotNetRDF, am I right with this?


Thank you,
Dennis
