As CarlosI raised in a previous mail [1], the dc:location property is not really defined by DC. We need to define an equivalent earl:location to describe a URI location.

At the same time, we agreed to develop an earl:Locator class that describe the occurrence of the result within the test subject. This class is to be a stub for several types of pointers such as XPointer, XPath, line/column numbers, byte offset, etc.

It occurs to me that this earl:Locator class should also have an earl:URI property. This would allow us to reuse the Locator to describe the test subject itself. Here an example:

<earl:Assertion rdf:ID="someID">
      <!--// this is the location of the subject //-->
      <earl:URI rdf:resource="http://example.org" />
    <!--// other earl:subject properties //-->
      <!--// this is the location of the result //-->
      <!--// more pointers if available //-->
    <!--// other earl:result properties //-->
  <!--// rest of the earl:assertion properties //-->

Thinking even further, the proposed earl:range/earl:scope (we should find a good name for this!) could be a further value type for the earl:Locator class.

Any issues with this approach?
