Contained resource metadata statements #96

Servers MUST NOT allow HTTP POST, PUT and PATCH to update a container’s resource metadata statements; if the server receives such a request, it MUST respond with a 409 status code. [Source]

Contained resource metadata statements include the properties:

rdf:type
A class whose URI is the expansion of the URI Template [RFC6570] http://www.w3.org/ns/iana/media-types/{+iana-media-type}#Resource, where iana-media-type corresponds to a value from the IANA Media Types [IANA-MEDIA-TYPES].

stat:size
A non-negative integer giving the size of the resource in bytes.

dcterms:modified
The date and time when the resource was last modified.

stat:mtime
The Unix time when the resource was last modified.

I assume this is a closed list of predicates, and for the rdf:type only when the object matches the regex.

Please feel free to edit this issue at will, or just close it and create a new one if you see a better way to formulate it. Thank you!
