pmlp:hasURL

[GoogleCodeExporter]

This was initially discussed at 
http://inference-web.org/wiki/IW_Meeting_2010-08-05 between Tim, Paulo, and 
Cynthia. We were discussing the example at 
http://inference-web.org/wiki/PML_example:_downloading_a_file

In the current ontology, pmlp:hasURL has a rdfs:domain of pmlp:Information.
Its current semantics:
* retrieving the value of pmlp:hasURL will be identical to the value of 
pmlp:hasRawString -- i.e. it points to the actual bit-level content that the 
instance of Information names.

a historical note: before pmlp:Information existed, x:hasURL had a domain of 
pmlp:Source. During this time, the current comment on pmlp:hasURL reflects its 
use: to point to a web page that describes the Source.

Since then, pmlp:Information was created and pmlp:hasURL got a domain of 
Information, but took on a new meaning (described above as "current semantics").

Current proposal:
deprecate use of pmlp:hasURL on instances of Information, and use the values of 
pmlp:hasURL as the name of the information itself.

start using y:hasURL on Source to point to relevant documents describing the 
Source. Note: this does not preclude the use of a dereferenceable URI to name 
that source, it simply provides in-line pointers to relevant documents. 
(y:hasURL should probably not be re-invented; we should use dc or foaf or 
something related).

re: "start using y:hasURL on Source to point to relevant documents describing 
the Source."
How about using rdfs:seeAlso?

rdfs:seeAlso is an instance of rdf:Property that is used to indicate a resource 
that might provide additional information about the subject resource.  It may 
be possible to retrieve representations of O from the Web, but this is not 
required. When such representations may be retrieved, no constraints are placed 
on the format of those representations.

Hi Tim,

When you refer to the "name of the information itself" do you mean the URI of 
the information instance?

Thanks,
Nick

Discussions are ongoing. Cynthia says she just needs the go-ahead, Paulo and 
Deborah want estimate of how much effort it will take.
