A voiD file is a machine-readable description of an RDF dataset. This specification describes how well-known URIs can be used to locate a voiD file that describes RDF data published on a given host.
The voiD guide [VOID-GUIDE] describes how to construct and deploy voiD files in order to describe datasets.
This specification makes use of the "well known URI" feature [RFC5785] of HTTP servers to provide a well known URI for voiD files, so that they can be
located by clients. It registers the well-known URI name "void" for voiD files. This means that the well-known location for a voiD file on the host
Note that the key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119].
2. voiD well-known URI
The ".well-known" URI "void" is registered by this specification for voiD files. The voiD files are described in the voiD guide [VOID-GUIDE], section "6.2 Publishing a voiD file alongside a dataset". The ".well-known" URI points to a resource that the client can use to retrieve the top-level voiD file for a dataset.
Clients MUST handle HTTP redirects on the ".well-known" URI.
