Wrong media type used for JSON(-LD)

[BigBlueHat]

The docs (and the responses themselves) use application/rdf+json for returning @graph-based JSON-LD documents. However, the correct media type is applicatoin/ld+json for that format.

For example:

curl https://id.nlm.nih.gov/mesh/D015242.json-ld

returns this content type:

Content-Type: application/rdf+json;charset=utf-8

As does the .json variant.

The application/rdf+json media type is used for a very different (and deprecated) JSON-based RDF format (known as "RDF 1.1 JSON Alternate Serialization (RDF/JSON)"):
https://www.w3.org/TR/rdf-json/#sec-examples

JSON-LD replaced that format:

...unless you have a specific reason to use the syntax defined in this document instead of JSON-LD, you are encouraged to use JSON-LD.

Please consider returning the correct application/ld+json media type for the .json-ld, .json, and content-negotiated (Accept: application/ld+json) requests (which, btw, currently returns n-triples).

Thanks for considering this!

I'll take a look. If this is a problem, I've contributed back the badness to lodestar upstream at EBI as well.

Let me know if you need any testing help. I'm mostly working with https://github.com/digitalbazaar/jsonld.js and https://github.com/RubenVerborgh/N3.js for dealing with stuff in the browser and node (fwiw).

Appreciate the help/time!

@BigBlueHat, I've issued a pull request to EBISPOT/lodestar. I'll include the fix in our downstream builds if it is accepted.

[danizen]

@BigBlueHat, this has been merged upstream, and we will install it during our next release. This is tentatively scheduled for the end of June.

Note - this will also affect auto conversion. That is, now if you send Accept: application/rdf+json, you will get JSON-LD. Once the change occurs, that will be Accept: application/ld+json. I will look into accepting both.

[danizen]

@BigBlueHat , please test - this should be done in production now. It was accepted upstream awhile ago, but I'm not in control of when it shows up at EBISPOT.

@BigBlueHat , I need to close this - we are moving away from Github Issues, and will be redirecting to our support site for support.

[BigBlueHat]

Sad things are moving away from GitHub. 😢 What will happen to the open source code? Is it also getting a new home (hopefully not behind closed doors)?

Thanks for letting me know regardless!

[danizen]

@BigBlueHat, no we are preserving the use of github, we are just moving the issues. We are preserving the open source code.

Phew! Thanks @danizen 😄
