Hi all,I am writing a paper and I would like to define the meaning of the Dereferencing URI on the Web.When resolve a URI on the traditional Web, we retrieve a document representation of the resource with status code 200OK, means we resolve the URI successfully. On the Semantic Web, when resolve a Real World Object URI, we cannot retrieve the object itself, but we will redirect to a information resource (a RDF document) which describes the URI, by parsing the RDF, we can understand the meaning of the URI according to the RDF triples description, we conclude that the request succeeded.Here are my definitions: *Resource: *Anything can be identified by a URI.
How about: Addressable via a URI?
Dereferencing URI: the act of retrieving a representation of a resource or the semantic description of a resource created by the URI owner.Dereferencing Succeeded: When dereferencing a URI, an agent successfully retrieved the representation of the resource or received the semantic description of a resource via the protocol specified within the URI.
All fine in the "Addressable" context. But, we are talking about Linked Data so you need to add:
1. Entity -- anything that could be Named using a URI and serve as the Subject of a description 2. Descriptor Resource -- a type of resource that bears/carries the description of a Subject.
Then you have:An addressable resource address (a kind of URI i.e., a URL) that resolves to the representation of the description of a Named Subject.
Basically, you are explaining indirection of the form:SubjectName (a generic URI) -->SubjectDescriptorResourceAddress (a URL) -->SubjectDescriptionRepresention (an eav/spo graph) .
