Some definitions (maybe)

[Patrick Durusau <patrick@durusau.net>]

Greetings,

In preparing for the meeting later today I noticed a couple of terms 
that I think have caused me to stumble in the ensuing discussion. Two in 
particular have been a concern.

Granularity: Bruce has remarked that the use of xml:id results in a lost 
of "granularity." Given my background with ISO 8879, I hear the term 
"granularity" as making reference to what can be marked up in a document 
instance. However, I don't think that is what Bruce means by that term.

Granularity in the sense Bruce is using the term means how to associate 
information with an rdf:about attribute. That is the implicit 
association of the subject-object-predicates in the RDF model.

In-context metadata: Elias uses the term "in-context" metadata to mean 
more than simply the recording of metadata inline. My error was in 
hearing "in-context" as the equivalent of "inline" metadata.

In-context metadata relies upon a mechanism specified in the RDFa 
whereby metadata such as the object or predicate of a triple may be 
contained by an element that has the rdf:about attribute. In terms of 
resolution, the processor walks up the containers until it finds the 
rdf: about attribute.

Hopefully Bruce and Elias can confirm these definitions before we start 
our meeting later today (or correct if I am completely off-base). I have 
long felt that we were missing each other due to different language 
practices but those are the hardest to resolve.

Hope everyone is having a great day!

Patrick
