I believe the current release of SiRPAC has a bug in parsing the syntactic
shorthand for statements about statements.
Given this RDF:
<?xml version="1.0"?>
<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
xmlns:a="http://description.org/schema/"
xmlns:dc="http://purl.org/dc/elements/1.0/">
<rdf:Description about="http:/www.w3.org/Home/Lassila" bagID="D_001">
<dc:Creator>Ora Lassila</dc:Creator>
</rdf:Description>
<rdf:Description aboutEach="#D_001">
<a:attributedTo>Ralph Swick</a:attributedTo>
</rdf:Description>
</rdf:RDF>
(taken directly from section 4.2 of the specification)
the on-line service generates the following:
triple('http://purl.org/dc/elements/1.0/Creator',
'http:/www.w3.org/Home/Lassila',
'Ora Lassila').
triple('http://www.w3.org/1999/02/22-rdf-syntax-ns#predicate',
'online#genid2',
'http://purl.org/dc/elements/1.0/Creator').
triple('http://www.w3.org/1999/02/22-rdf-syntax-ns#subject',
'online#genid2',
'http:/www.w3.org/Home/Lassila').
triple('http://www.w3.org/1999/02/22-rdf-syntax-ns#object',
'online#genid2',
'Ora Lassila').
triple('http://www.w3.org/1999/02/22-rdf-syntax-ns#type',
'online#genid2',
'http://www.w3.org/1999/02/22-rdf-syntax-ns#Statement').
triple('http://www.w3.org/1999/02/22-rdf-syntax-ns#type',
'online#D_001',
'http://www.w3.org/1999/02/22-rdf-syntax-ns#Bag').
triple('http://www.w3.org/1999/02/22-rdf-syntax-ns#_1',
'online#D_001',
'online#genid2').
triple('http://description.org/schema/attributedTo',
'online#online#genid2',
'Ralph Swick').
I believe the last triple should be:
triple('http://description.org/schema/attributedTo', 'online#genid2','Ralph
Swick').
The 1.14 download exhibits a similar problem; it creates:
(http://description.org/schema/attributedTo, genid3, Ralph Swick)
instead of:
(http://description.org/schema/attributedTo, genid2, Ralph Swick)
Can anyone confirm that this is a bug? Thanks,
