Which IPTC Field does "Copyright URL" map to ?

[a_mumford]

For some reason looking at the IPTC Core specs (2014) I'm having trouble identifying what the exact IPTC Field name is for "Copyright URL". I can find almost everything else but not this one - could someone from CameraBits point me to the correct Field ?

Thx

The Copyright URL is written only to XMP and not the old IPTC binary field format.  It is written with the tag "WebStatement" in the XMP Rights namespace "http://ns.adobe.com/xap/1.0/rights/".

Does that answer your question?

Ah yes - so we're saying it's not an official part of the IPTC spec, yes ?

No, not at all.  It is part of the IPTC4XMP specification.  The original IPTC specification is for all purposes dead, but we still support it.

XMP is where all new metadata standards are going now.

Ok so this is where I get confused and beg your indulgence ?

So it's in the photoshop namespace and it's not going to be an embedded value but the PLUS standards are now part of the latest published 1.4 standard - are they not XMP only fields as well ?

Who curates / maintains / publishes IPTC4XMP if not IPTC ?

Thx

The Metadata Standards Working Group (MWG) and the International Press Telecommunications Council (IPTC) but when I say IPTC vs XMP, I am talking about the obsolete binary IPTC format versus the XML-based XMP format.

Perhaps if you rephrase your question I can try again to answer.  The Copyright URL field in PM is represented in XMP as "WebStatement" in the XMP Rights namespace "http://ns.adobe.com/xap/1.0/rights/".

So basically when you enter a Copyright URL and then save the metadata, it is written to XMP like so:

Code: [Select]

<x:xmpmeta xmlns:x="adobe:ns:meta/" x:xmptk="XMP Core 5.1.2">
 <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#">
  <rdf:Description rdf:about=""
    xmlns:xmpRights="http://ns.adobe.com/xap/1.0/rights/"
   xmpRights:WebStatement="http://www.someurl.com/"
  </rdf:Description>
 </rdf:RDF>
</x:xmpmeta>

Specifically like this:  xmpRights:WebStatement="http://www.someurl.com/"

When PM loads XMP metadata, it looks for the WebStatement and puts it in the "Copyright URL" field.

I hope this makes things clearer.
