如何添加点“。” 以Sparql中个人的名义？

Question

Is it possible to have a . (dot) in the qname of individuals or RDF resources in general?

Something like this?

SELECT  ?tableName ?fieldName 
WHERE { ?fieldName hrdata:relatedField hrdata:ps_ti0002.EMPLID. }

The dot in ps_ti0002.EMPLID is problematic.

Answer 1

your code is right and should work. It is possible to use dot in the individual's name.

I think you should check your data property (relatedField), maybe is not clarified right.

Answer 2

Unfortunately, I still can't comment - but I think your answer is wrong and a dot is not allowed in prefixed URIs/IRIs as you can try out using the validator suggested by @AndyS .

Answer 3

The . is allowed in SPARQL and the SPARQLer Query Validator demonstrates. However, there are a couple of suggestions to help you get this working. First is to have a space after the qname, ie:

WHERE { ?fieldName hrdata:relatedField hrdata:ps_ti0002.EMPLID . }

Another is to use the fully qualified URI. Suppose the namespace for hrdata is http://example.org/hrdata/ , the the following query should work:

SELECT  ?tableName ?fieldName 
WHERE { ?fieldName hrdata:relatedField <http://example.org/hrdata/ps_ti0002.EMPLID> . }
