Re: [Rdfapi-php-interest] Unbound Prefix

[Marco R. <cre...@go...>]

Thank you all!

It looks like a classical human failure - problem to me :))
But it works just fine now. By declaring the right namespaces with the right
URIs I even get the results I expect!

While we are at it two more questions:

1.) Does RAP come along with a count-construct in the select-statement? I
only found information, that count returns an integer, but nothing further
more. So is it possible to use somelike

prefix ... select count(?var) where {...}

2.) My rdf-dump declares namespaces with uris. Therefore shouldn't it
possible to use my query-statements without using the PREFIX-constructs?

The xml-file starts like this:
