What is needed to reuse data?

[codersquid]

This topic is closely related to #2.

In the context of figit and other tools, what would we ask for authors to put in a repo to get packaged up with the data? The dataprotocols project is working towards a standard data package description in data-package.json, There is some interesting discussion in https://github.com/dataprotocols/dataprotocols/issues/110 about use of data-package.json and package.jsonld.

Along with a README or other helpful files, an author could include a data package description file.

Since I think the concept will be confusing to many people, we could provide some minimum recommendations for what to include in a README as a first step, and then perhaps have pointers to more advanced methods (such as how create a package definition file).
