Re: ISSUE-49 (are graphs information resources?)

From: Chimezie Ogbuji <ogbujic@ccf.org>

To: "Gregory Williams" <greg@evilfunhouse.com>, "SPARQL Working Group WG" <public-rdf-dawg@w3.org>
Message-ID: <C7F35CD3.11328%ogbujic@ccf.org>
Per my action (ACTION-116), I have suggested modifications to the text.
First, a new entry in the terminology section (under IRI):

* Graph Store - An RDF dataset whose named graphs can be added to or deleted
from [SPARQL Update].

Modify from:

[[[ Network-manipulable RDF (Dataset) - An RDF dataset used by an
implementation of this protocol whose named RDF graphs are the targets of
the operations and their identifiers are resolvable URIs or URIs that can be
embedded in the query component of URI in a manner described later in this
document
]]]

To 

[[[
Network-manipulable RDF -  A graph store used by an implementation of this
protocol whose named RDF graphs can be managed by HTTP operations and their
identifiers are resolvable URIs or URIs that can be embedded in the query
component of URI in a manner described later in this document
]]]

New entries:

* Graph IRI - The IRIs involved in this protocol that are specified as a
request URI or embedded as a query component *and* correspond to the IRIs in
the underlying Network-manipulable RDF.   
* RDF document   - A serialization of an RDF Graph into a concrete syntax
[RDF-XML].

[[[
Networked RDF knowledge - ... snip ... An information resource, identified
by the IRI of a graph in a network-manipulable RDF dataset ...
]]]
==>
[[[
Networked RDF knowledge - ... snip ... An information resource, identified
by a graph IRI ...
]]]

In every other similar case where there is a reference to dataset, replace
with graph store.

Add a new sentence to the last paragraph in 2:

[[[
Following the terminology in [AWWW], the intuition here is that messages in
this HTTP protocol use graph IRIs to access the underlying graph store.  The
graph IRIs identify networked RDF knowledge.  Networked RDF knowledge is
distinguished from other kinds of (information) resources by the fact that
they are primarily represented by an RDF document and these RDF documents
are serializations of RDF graphs in the underlying graph store.
]]]

In 4.1:

[[[
We recall from [SPARQL] that IRIs for RDF graphs in SPARQL queries identify
a resource, and the resource is represented by a graph (or, more precisely:
by a document that serializes a graph)
]]]

==>

[[[
We recall from [SPARQL] that IRIs for RDF graphs in SPARQL queries identify
a resource, and the resource is represented by a graph.
]]]

In the third paragraph of this section:

[[[
In our example, the corresponding request URI
(http://example.com/rdf-graphs/employees) is meant to identify RDF triples
on the example.com server that describe employees ..
]]]
==>
[[[
In our example, the corresponding request URI
(http://example.com/rdf-graphs/employees) is a graph IRI that identifies RDF
knowledge about employees ..
]]]

In section 5
[[[
.. snip ... performed on Networked RDF knowledge. Where an equivalent SPARQL
Update operation is given, <graph_uri> is understood to be either the
request URI or the URI indirectly specified via the query component as
described above. 
]]]
===>
[[[
... snip .. performed on Networked RDF knowledge. Occasionally, an analogous
SPARQL Update operation is given to demonstrate how the operations are
interpreted.  This is meant to be informative and does not dictate a formal
binding between the two protocols.  Within the given analogous SPARQL Update
operations, <graph_uri> is understood to be a graph IRI.  As mentioned
previously, these do not directly identify the RDF graphs. 
]]]

And wherever the document says 'is equivalent to' (in reference to the
analogous SPARQL Update operations) this should be changed to 'is analogous
to'
