9.1 Property Path Syntax

Hello,

I am looking at implementing a small subset of the SPARQL 1.1 Property Path
syntax in EasyRdf. Although it doesn't support SPARQL querying internally,
the property path syntax is useful for fetching values like this:
$names = $person->all('foaf:knows/foaf:name');


However I am finding the Property Path Syntax for an IRI is slightly
confusing:
"iri is either an IRI written in full or abbreviated by a prefixed name"

How should implementers distinguish between an IRI and a property path?
Shouldn't a full IRI be enclosed in angle brackets?
<http://xmlns.com/foaf/0.1/knows>

Hence property paths can only be used with prefixed names? I think an
example might help.


Thanks,

nick.
