Hi Boris, Unfortunately I'm not very familiar with that method -- can you provide some more details into exactly what its supposed to do? All of the connectors for implementing the sail api are in the rya.sail, and the main classes to look at are RdfCloudTripleStore, RyaSailRepository, and RdfCloudTripleStoreConnection. All of these classes all extend abstract implementations SAIL provides out of the box, so typically the way you extend them to do more stuff is to look at the Sail implementation and customize it for Rya's data structures. If you need any help or want to bounce any implementation ideas off of anyone, please send out an email over the dev list. Just let us know how we can help! Thanks, Puja
