I have a couple of lofty questions about ISO19115/19139 and how =
interprets the specifications.
Reading ISO19115 there are a number of constraints that fall outside the
control of the XSDs implemented by 19139 (in the official documentation =
are referred to as 'co-constraints' or 'conformance rules'), for =
"'densityUnits' is mandatory if 'density' is provided".=20
Does conforming to ISO19139 simply mean that your XML is valid against =
XSDs? Or must the XML hold up to further interrogation to test the
conformance rules in order to claim that is it ISO19139 compliant?
What is the commonly held view in regards to these constraints? And what =
claim does GeoNetwork make in regards to these constraints?
I have the spec here but I am asking as there seems to be some degree of
uncertainty given the language used in this section of the document and =
feel its going to be the ground swell by vendors that will define more
clearly the impact of this section of the documentation.
