Topic Maps are often mentioned as a XLink success story and that's the
second time they are coming quoted in this thread and that'll give me
the opportunity to express a point that's been bothering me for a while.
I am not really a Topic Maps expert and most of what I know about Topic
Maps has been acquired sitting in discussions between RDF and TM geeks.
One of the thing which kept popping up is that TM are about defining
links with multiple arcs and this is the domain of extended XLinks.
However, XTM has chosen, for the sake of simplicity, to use simple links
rather than extended links.
As far as I remember, the XLink recommendation sees the other way round
and sees simple links as a specific case of extended links
Using XLink to simulate extended links with a bunch of simple links
looks to me like saying: "OK; we'll take the syntax so that we can say
we are compliant but we'll attach a slightly different meaning".
If I am right, XTM can hardly pretend to be using XLink :) ...
OTH, if I am wrong, the XLink recommendation should better have defined
simple links only and explained how extended links can be built from
simple links.
