The file seems to be invalid Turtle. Line 108. Other libraries also cannot parse that file.

Hi Holger,

 

So

 

              skos:example

                            spec11:B.1.2.4 ;

 

(and all other example clauses)

 

are invalid? (so the dots in the name?)

 

The strange thing is:

The turtle validator, http://ttl.summerofcode.be/ , says:

 

 

Isn’t it just a path with dots in it?

 

Thx michel

Some more…

 

Suppose we have:

 

 

(having also a dot).

 

Wouldnt it be poss. to have an alternative shortend prefix like:

 

dc-short: http://purl.org/dc/

 

then resulting in dc:short:elements/1.1/

 

(similar like spec11:B.1.2.4 ;)

which should be 
and remove the last semicolon in line 108

Even more:

 

The issue seems actually with red:

 

<http://www.opengis.net/ont/geosparql>

              a owl:Ontology ;

              dcterms:source "OGC GeoSPARQL – A Geographic Query Language for RDF Data OGC 11-052r5"@en ;

              rdfs:seeAlso <http://www.opengis.net/doc/IS/geosparql/1.1> ;

.

 

And now the weird thing:

 

Changing

 

              dcterms:source "OGC GeoSPARQL – A Geographic Query Language for RDF Data OGC 11-052r5"@en ;

to

              dcterms:source "x"@en ;

 

solves the issue…

 

????

 

Some strange control character somewhere?

Yep sorry, was typo

 

Semicolon 108 seems fine to me.

 

I discovered in issue at some other plave in geosparql, see my next mail….

Holger, I know you like minimal examples 😊

 

The dash is causing the issue …

 

              dcterms:source "GeoSPARQL – "@en ;

 

deleting this dash solves the problem ….

 

Is this “a bit bigger than a normal dash” a special character not allowed in an rdf/turtle string?

I expect that is a special character that has to be escaped to be valid RDF Turtle.

See here and search for “escape” and you find:

Note

Prefixed names are a superset of XML QNames. They differ in that the local part of prefixed names may include:


Cheers,

Ok

But adding just a \ does not solve the issue

 

How would they need to escape in:

 

http://www.opengis.net/ont/geosparql

              a owl:Ontology ;

              dcterms:source http://www.opengis.net/doc/IS/geosparql/1.1 , "OGC GeoSPARQL – A Geographic Query Language for RDF Data OGC 11-052r5"@en ;

.

 

Then I can report that back to OGC (via our Dutch contact)

Hi Michel,

If you are talking to standards makers, then this detail is something to be understood with them using the RDF Turtle spec. It is not specific to TopBraid so you should do what the spec says, not what TQ says, and if that works in other tools but does not work correctly in TopBraid, then raise a ticket with Support. 

As you can see from what I pasted, I found something about QNames when you are actually looking at lang string-valued properties. I think the section you need may be this one 


with gory details about unicode (with links to the unicode standard) but I do not have time to test the various possibilities for you wrt the exact character being used (e.g. is that an emdash?) and its encoding:

Cheers,
David

All clear

 

I will advice them to use a normal dash to avoid gory unicode details 😊
