Subject: ISSUE: relative URIs in 'linkuri'
Ref: http://lists.oasis-open.org/archives/cgmo-webcgm/200509/msg00093.html Comments: 20 ========== ISSUE: how are relative URIs in 'linkuri' resolved? DISCUSSION: Dieter writes, "something should be added to say that xcfurls can be relative but can also be absolute. Also, we need to make a comment about relative URLs found in linkURIs then, the processing there is different, if I remember correctly.There it is relative to the container document I think." The first sentence is strictly editorial. The second is not so straightforward. A 'linkuri' could occur: -- in a WebCGM instance; -- in DOM script; -- in XCF instance. As I understand it, the container document would be the WebCGM, a HTML/JS file, the XML file of the XCF. I don't think we want the relative URI of a 'linkuri' to resolve to the container document. For example, load this CGM Container: http://www.example.org/webcgm/myCGM.cgm linkuri: #another-obj-in-this-pic Then we edit the DOM of that already-loaded WebCGM, with this DOM script, to change that linkuri... Container: http://www.example.org/domScripts/myDOMtest.html linkuri: #a-third-obj-in-this-pic I don't think we want the linkuri to all of a sudden be relative to myDOMtest.html. Or am I misunderstanding the meaning of "container document"? I think we want something like ... relative URI in 'linkuri' resolves relative to the WebCGM "that contains it". I quoted the latter because I'm not quite sure the right way to express it. But ... if the 'linkuri' is in a WebCGM, no problem. If it is in DOM script or XCF ... well, the 'linkuri' in a sense is really contained in the WebCGM, and those (DOM script / XCF) are just editing directives that are being applied, to change the 'linkuri' value in the WebCGM. RECOMMENDATION: relative URI in 'linkuri' resolves relative to the WebCGM "that contains it". Discussion? (Suggestions for the best way to say it?) Regards, -Lofton.
