SRU response does not include the resource location #262

@lmika-bom Is this true? @6a6d74 has been challenged by WMO Dave Thomas on this. Though Jeremy thinks the tech specs do not require this, we would like to know if OpenWIS does or does not do this.

New Zealand DCPC provides a SRU search page that allows users to find records in the WIS Catalogue http://www.metservice.com/maps-radar/wis-search/search) ... Dave Thomas identifies this as "the way it should be done".

OpenWIS doesn't appear to include the location of the resource in its SRU response ...

Compare requests between GISC Offenbach and GISC Melbourne SRU servers:

GISC Offenbach: 

http://sru.dwd.de/SRU2JDBC/sru?operation=searchRetrieve&version=1.1&query=%22temperature%22%20and%20%22berlin%22&startRecord=1&maximumRecords=10&&stylesheet=xsl/dwd-sru.xsl&x-dwd-stylesheetDetailLevel=2

You can see the URL of the resource provided ... 

OnLine resource

    gmd:URL    http://dcpc.worldweather.org

By comparison, GISC Melbourne provides a limited set of metadata elements:

So GISC Melbourne doesn't actually tell you where the resource is!!!

@benjaminsaclier asks whether the SRU response is part of the GeoNetwork code base or OpenWIS Core?
