[galaxy-dev] Graph Datatypes

Hi, we are currently working on a few graph based tools and we would like to add some new graph-datatypes, namely: gspan, gml, gexf, graphml, pajek. I saw that xgmml and sif are already integrated into core-galaxy and I'm wondering if a PR with these new datatypes would be appropriate or a new toolshed repository? Also, are there any plans to enhance graphview in the near future? Thanks, Bjoern
