I agree with Marko's thoughts, both on this topic of including sparql-gremlin as well as the wider topic of what should be included in TinkerPop code base more generally. Providing a path for rdf/sparql folks to get into the TinkerPop world seems like a smart direction.
Now, assuming that we have consensus to include sparql-gremlin in the TinkerPop code base, the process will look something like this: 1. I think that Harsh should fork the TinkerPop repository and migrate sparql-gremlin into its structure. From there we will provide feedback/review to get that fork into best shape possible prior to his submitting a pull request. I think we can handle initial feedback through the dev list in a separate thread. 2. In parallel to the above item, it appears as though there are two contributors on sparql-gremlin: https://github.com/LITMUS-Benchmark-Suite/sparql-to-gremlin/graphs/contributors Both contributors, Harsh and Dharmen, should submit ICLAs: http://apache.org/licenses/icla.pdf and send them to [email protected]. 3. Once ICLAs are confirmed by secretary, Harsh can submit a pull request from his fork where it can under go final review. Does that sound sensible to everyone? btw, Harsh, it sounds as though you intend to continue development on sparql-gremlin after it is part of the TinkerPop repository...does Dharmen intend to do the same?
