Hi List,
I have a couple of lofty questions about ISO19115/19139 and how GeoNetwork 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 these are referred to as ‘co-constraints’ or ‘conformance rules’), for example: “’densityUnits’ is mandatory if ‘density’ is provided”.
Does conforming to ISO19139 simply mean that your XML is valid against the 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 does 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 I feel its going to be the ground swell by vendors that will define more clearly the impact of this section of the documentation.
Cheers,
Michael Gannon.
