Better show the output then expain.
Here is how a document with entity of type url and action with that url looks like:
(showing only the entity and the relation)
[http://d.opencalais.com/genericHasher-1/6e593c74-0e8f-3c1a-bd68-fcf86f95273d] => Array
        (
            [_typeGroup] => entities
            [_type] => URL
            [name] => www.reliefrun.com
            [_typeReference] => http://s.opencalais.com/1/type/em/e/URL
            [instances] => Array
                (
                    [0] => Array
                        (
                            [detection] => [ you’d like to participate, visit the website at  ]www.reliefrun.com[  for more details and to     RSVP.]
                            [prefix] =>  you’d like to participate, visit the website at 
                            [exact] => www.reliefrun.com
                            [suffix] =>   for more details and to     RSVP.
                            [offset] => 1274
                            [length] => 17
                        )

                )

            [relevance] => 0.107
        )
[http://d.opencalais.com/genericHasher-1/8af26685-05cb-379a-9c3c-76091bd1e9cf] => Array
        (
            [_typeGroup] => relations
            [_type] => ContactDetails
            [contacttype] => Contact
            [_typeReference] => http://s.opencalais.com/1/type/em/r/ContactDetails
            [url] => www.reliefrun.com
            [instances] => Array
                (
                    [0] => Array
                        (
                            [detection] => [ you’d like to participate, visit the website at  ]www.reliefrun.com[  for more details and to     RSVP.]
                            [prefix] =>  you’d like to participate, visit the website at 
                            [exact] => www.reliefrun.com
                            [suffix] =>   for more details and to     RSVP.
                            [offset] => 1274
                            [length] => 17
                        )

                )

        )
 
 
The relation should give up the calais id - http://d.opencalais.com/genericHasher-1/6e593c74-0e8f-3c1a-bd68-fcf86f95273d
But it shows the url value - www.reliefrun.com
So the relation should look like:
[http://d.opencalais.com/genericHasher-1/8af26685-05cb-379a-9c3c-76091bd1e9cf] => Array
        (
            [_typeGroup] => relations
            [_type] => ContactDetails
            [contacttype] => Contact
            [_typeReference] => http://s.opencalais.com/1/type/em/r/ContactDetails
            [url] => http://d.opencalais.com/genericHasher-1/6e593c74-0e8f-3c1a-bd68-fcf86f95273d
            [instances] => Array
                (
                    [0] => Array
                        (
                            blah blah
                        )

                )

        )
 
All of the relations with entity of type URL in them come like this.
