Problem/Motivation

The JSON:API spec states

A link object MAY also contain any of the following members:

  • rel: a string indicating the link’s relation type. The string MUST be a valid link relation type.

The linked RFC 8288 describes a valid extension link relation type:

Applications that don't wish to register a relation type can use an
extension relation type, which is a URI [RFC3986] that uniquely
identifies the relation type.

However, LinkCollection::validKey() validates link relation types using a custom-ish(?) method which disallows colons. Colons are valid in URIs, including URNs.

Steps to reproduce

Attempt to utilize a link relation type with a colon, e.g. urn:kinksters-link:cancel.

Proposed resolution

Validate the link relation type per the ABNF in the HTTP linking RFC.
