JSON-LD

[hupili]

As is mentioned in #90 JSON is an important interfacing format to support. We already make the Message object JSON-serializable for interfacing with any other languages. It will be better to have general JSON support in form of a platform.

JSON-LD looks a promising direction.

Notes from the introductory video of JSON-LD: http://www.youtube.com/watch?v=vioCbTo3C-4

• HTML (rendered): human consumption.
• HTML + RDFa: machine readable linked data. e.g. for search engines.
• JSON: common interfacing format. Problem is that there is no common agreement of the meaning of attributes. We find this especially true with the experience in developing SNSAPI.
• JSON-LD: use @context to make the meaning of fields unambiguous. Other specifiers: @id, @type, ...

The idea of JSON-LD is self-descriptive. @context can be put in the JSON file or in a separate .jsonld file. Current examples extensively refers to http://schema.org/ . e.g. ReplyAction. The definition looks too detailed and overwhelming to new users. We may want to maintain a snsapi-message context
