preaching to the choir ?!?

RDF needs necktiesseems more controversial

provenance, source, origin, author,…
creation date, age, use-by date,…
accuracy, authentication, certification, validity, …
context, assumption, modality, …
dependencies, disjunction, negation, …
access rights, copyrights, …
location, society, culture, …
...informational context

wecanquery…
PREFIX dc: <http://purl.org/dc/elements/1.1/>
PREFIX foaf: <http://xmlns.com/foaf/0.1/>
SELECT *
WHERE
{
GRAPH ?gphdoc { ?docdc:title ?title .
?docdc:creator ?author }
GRAPH ?gphauthor { ?authorfoaf:name ?name }
}

wecannotname…
reification quads do not imply the triples, no link
rdf:ID still at triple level and still no link
document URI, ad-hoc, bad practice
… naming is currently done outside RDF
#me

subject
#name
predicate
#S
#me
#name
"fabien"
object
"fabien"
#me


named graphs, provenance and trust
[Carroll, Bizer, Hayes, Stickler, 2005]
communicate assertional intent and sign assertions
embody social acts with some record
name with URIs & graph RDFS class

names, plllleaaase,@TODO blank nodes, one triple in several graphs, backward compatibility, rdf:Graph & rdf:GraphStore// comments - RDF 1.1 not RDF 2.0 - Follow your nose for RDF and named graphs - RDF meta-model must remain domain independent to standardize a best practice there must be a practice in the first place
