Hello all, I have been reading about namespaces in general and xlink in particular. According to the xlink spec, xlink:type="simple"is required for a simple (i.e. not extended) link, which is the way THREDDS is using xlink. Adding it means software that is xlink-aware (mozilla for one) will display links as links, though in mozilla's case, it is only apparent if you add a<?xml-stylesheet type="text/css" href="threddsstyle.css" ?>line to the thredds catalog so that mozilla actually processes the xml file in a standard way.I have added it to the THREDDS catalogs I generate, with no obvious ill effects so far.If there are ill effects, please let me know.I would hope that the THREDDS standard would add this so that the THREDDS xml is better understood by more software.Benno
Hi Benno: yes, we do already allow the "show" and "type" attribute on an Xlink, see: http://www.unidata.ucar.edu/projects/THREDDS/tech/catalog/InvCatalogSpec.html#XLink
XLink Attribute Group <xsd:attributeGroup name="XLink"> <xsd:attribute ref="xlink:href" /> <xsd:attribute ref="xlink:title" /> <xsd:attribute ref="xlink:show"/> <xsd:attribute ref="xlink:type" /> </xsd:attributeGroup>These are attributes from the XLink specification <http://www.w3.org/TR/xlink/> that are used to point to another web resource. The /xlink:href/ attribute is used for the URL of the resource itself. The /xlink:title/ attribute is what should be displayed to the user. These are the only two attributes currently used in the THREDDS software.You can also add the /xlink:type /or/ xlink:show /attributes/. /
