It's not a big data set that lends itself primarily to analysis, it's more like content. For example, a list of all US Presidents with a lot of metadata or text content fields about them collected/combined from different sources, cleaned, corrected, annotated, etc. (Pretend Wikipedia has only a subset of these fields and considers broadening them out of scope.)

As for Github, the data would still be under "my" account and I'm thinking about more of a platform that doesn't depend on one person. Maybe I would manage day to day version control in Github but I'd want to promote occasional releases to be more official and not reliant on my account.
