LoMap format specification

This Issue is only to discuss the format to use to save the data in the SOLID pods (such as using plain JSON, using JSON-LD, following the RDF format, etc), not to discuss what information to store (latitude, longitude, description, score, etc).

Please stick to the subject, and use other issues to talk about other subjects, thank you.

Start with the issue discussion, which is limited to choosing a format for data saved in SOLID pods. Review the alternatives named there—plain JSON, JSON-LD, and RDF—and the existing LoMap specification context if available. Done requires a decided format specification; the issue does not identify files, tests, or an implementation entry point.
