Why sparql spec? Isnt this an rdf/rdfs issue?

Ie: in rdfs spec:
2.1 rdfs:Resource
All things described by RDF are called resources, and are instances of the 
class rdfs:Resource. This is the class of everything. All other classes are 
subclasses<http://www.w3.org/TR/rdf-schema/#def-subclass> of this 
class.rdfs:Resource is an instance of 
rdfs:Class<http://www.w3.org/TR/rdf-schema/#ch_class>.

WHAT AM I MISSING? ☺

Subject: Re: [topbraid-users] support for rdf:value

It is a literal with a value of 12.0 that is equivalent to "12.0"^^xsd:float.  
For more, see the grammar section of the SPARQL W3C recommendation.

What happened? Is it now a resource after all?

Thx scott/irene

But can I still use it to store a value like “12.0”^^xsd:float?

To add to this, the answer is apparent from the user interface.

In the image below, you can see a purple diamond to the left of rdf:value 
field. This means that a resource, not a literal is expected.

Michel, the domain and range of rdf:value is rdf:Resource, so I would suggest 
using "Create and add..." or "Create blank node...".

When you do it in source code tab:
And then switch you get:

So fine.

Clearly, I’dd like to be able to use the forms tab in the first place…

Subject: Re: [topbraid-users] support for rdf:value

Michel; Yes, rdf:value is supported in TopBraid.  One way to verify is to 
CONSTRUCT some rdf:value values:

CONSTRUCT
{ exproduct:item10245   exterms:weight   _:weight10245 .
_:weight10245         rdf:value        "2.4"^^xsd:decimal .
_:weight10245         exterms:units    exunits:kilograms .
}
WHERE {
}

Also, the properties pane does not show all properties in the RDF vocabulary.  
See Preferences > TopBraid Composer > Properties View and you can select 
rdf:value to appear in the Properties View.

I define a pattern where a quantity class has a value and a unit.

I defined ext:hasValue for this myself.



I discovered however in 
http://www.w3.org/TR/2004/REC-rdf-primer-20040210/#rdfvalue

the existing construct for exactly this purpose! (n-ary 
relationships/structured values).



But is this rdf:value supported in TBC? I cant find it :)



Thx for feedback,

Michel
