Andy Seaborne commented on JENA-297:
------------------------------------
This is a question - maybe the users mailing list is better? It certainly
isn't "critical".
You will need to ask the Protege people about Protege.
Jena parses that file just fine:
rdfcat eu1.n3 =>
<rdf:RDF
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#";
xmlns:j.0="http://aNameSpace/";>
<j.0:BrokenThing rdf:about="http://aNameSpace/TestWith%3AColon"/>
<j.0:BrokenThing rdf:about="http://aNameSpace/TestWith3AColon"/>
</rdf:RDF>
riot eu1.n3 ==>
<http://aNameSpace/TestWith%3AColon>
<http://www.w3.org/1999/02/22-rdf-syntax-ns#type>
<http://aNameSpace/BrokenThing> .
<http://aNameSpace/TestWith3AColon>
<http://www.w3.org/1999/02/22-rdf-syntax-ns#type>
<http://aNameSpace/BrokenThing> .
Jena also correctly calculates namespace and local name according to the rules
of XML Namespaces.
"TestWith%3AColon" is not a valid local name.
The spec is:
http://www.w3.org/TR/REC-xml-names/
A local part of an XML
[8] PrefixedName ::= Prefix ':' LocalPart
[11] LocalPart ::= NCName
[4] NCName ::= Name - (Char* ':' Char*) /* An XML Name,
minus the ":" */
In XML, 'Name' can not have a % in it.
You can not have raw colon in an XML prefixed name.
In RDF/XML, only properties must be in prefixed name form. Subject and objects
can be written in long form in strings as shown above.
Note: %3A is not putting a colon in a URI. It is not an escape mechanism - it
encodes. The URI really does have the 3 characters %-3-A in it.
> N3 Parser and escaped ( %3A ) colon

> Having the following n3 file, I get a tottaly different behaviour when
> calling getNameSpace() and getLocalName for the resources.
> For resource:
> <http://aNameSpace/TestWith%3AColon>
> I get:
> namespace: http://aNameSpace/TestWith%3A
> LocalName: Colon
> For resource:
> <http://aNameSpace/TestWith3AColon>
> I get:
> namespace: http://aNameSpace/
> LocalName: TestWith3AColon
> First one is wrong, second is correct.
