it's a part of what they do, but less. and please keep in mind that the
draft that's published is very rough and incomplete, so some of what i
am saying is just what we wanted to do with the descriptions, but has
not necessarily found its way into the draft.
what link descriptions also are supposed to do is to describe data types
and value ranges. for example, when you have a page variable, then you
want to represent the fact that it's integer, and the allowed value
range. from what i can see, hydra does not support this kind of
information, which, like you say, is going in the direction of forms
(not the UI part, but the logical part).
i guess what hydra *could* do would be (and i am using XSD here because
it conveniently exists as a simple datatype standard on the web, but
sadly defines no URIs to identify its core concepts):
{
"@context": "http://www.w3.org/ns/hydra/context.jsonld",
"@type": "IriTemplate",
"template": "http://api.example.com/issues{?page}",
"mapping": [
{
"@type": "IriTemplateMapping",
"variable": "page",
"datatype": "http://www.w3.org/TR/xmlschema-2/#integer",
"xs:minInclusive": "1",
"xs:maxInclusive": "42",
"property": "http://example.com/feedpaging/page",
}
]
}
cheers,
dret.
