Hello, I've been spending a bit of time looking over Data Sources <https://wiki.galaxyproject.org/Admin/Internals/DataSources> for Galaxy. I've been thinking about designing a tool in Galaxy, similar to a Data Sources tool, which would take as input a file defining a list of URLs to import into Galaxy, along with some user credentials. In this sense it would be similar to the GenomeSpace <https://bitbucket.org/galaxy/galaxy-dist/src/579d211c2b0fa8ef4195930cb999edbb9a0cf8eb/tools/genomespace/?at=default> importer tool.
However, instead of just exporting a set of files to a user's history, I'd like to be able to also automatically group these files into a dataset collection. I would also like to be able to link to these files instead of creating copies (which I think I can only do through a Data Library am I correct?). Ideally, I'd like to be able to use this tool as the first step in a workflow, which would allow me to import and structure the data needed for the rest of the workflow. Does anyone have any experience writing a similar tool? Is this possible in the current Galaxy version? Thanks, Aaron
