Description
Maybe I understand something wrong here, but the spec says:
Unless otherwise noted, objects defined by this specification or any applied extensions MUST NOT contain any additional members. Client and server implementations MUST ignore non-compliant members.
Furthermore the spec says:
The optional links member within each resource object contains links related to the resource.
If present, this links object MAY contain a self link that identifies the resource represented by the resource object.
I interpret this language so that the following JSON would NOT be compliant with the spec:
{
"data": {
"id": "4",
"type": "movies",
"attributes": {
"title": "The Matrix"
},
"links": {
"imdb": "https://www.imdb.com/title/tt0133093/"
}
}
}If my interpretation is right, please allow custom links. Otherwise many REST hypermedia use cases could not be implemented in a spec-compliant way.
If my interpretation is wrong, please clarify the language of the spec by explicitly adding language to allow custom resource links.
Just a side note: If you validate the above JSON with https://www.jsonschemavalidator.net/ (and use the provided JSON:API schema), it says it is valid JSON:API.
