How does SoLiD plan to deal with 'application/activity+json' ? about solid-spec

[deiu]

Our two SoLiD servers (gold and ldnode) both support JSON-LD (application/ld+json). The SoLiD document speak about JSON-LD, because it is just another serialization format.

This issue is about the current requirement by Activity Streams 2.0 to support a new special Activity Streams 2.0 media type instead of the JSON-LD media type (with a profile).

[deiu]

I see. I believe it is less likely that SoLiD will support the application/activity+json media type, at least in the near future.

It should be fine to accept it as a synonym for json-ld during writes. The question is when it's okay to serve it, and I'm not exactly clear about that. What is the subset of json-ld that is also activity+json. Hmmm.

@deiu

I have a couple of additional questions related to JSON :
In this talk it was said that it only depends on the URI ...
However – to have an idempotent and restful "JSON handling" the spec. should allow that

PATCH with sparql-update

could also be JSON Patch
and how about

Link: https://example.org/data/.meta; rel="describedby"

• Could this also be a JSON schema:
  RFC core, validation, hyper-schema ?

PATCH with Json Patch on an LDP server is something that would be possible, but it would require a server to be able to keep a stable copy of the serialisation of the data. It would also require the client to keep a very good copy of the serialised data - Different parsers in JS act quite differently, so it may not be very reliable. In any case once you build Linked Data apps you'd on the whole like to get away as far as possible from thinking about serialisations. It is costly to maintain on the client and the server.

Still if you drop JSON Documents into an LDP Container - then it should be possible to edit them with JSON Patch. The LDP spec does not disallow that.

Closing. Moving to:

• solid/#82-JSON Patch support
• solid/#83-AS2 Integration / support for 'application/activity+json' content type
