RE: XML, hypertext
Hi Bob Bob said: Maybe a good working definition of hyper(text/link/media) is something we need to start with, if that's what we're building around. The XLink Rec (and despite my complaints about the it, I do like its definitions) defines a hyperlink as "a link that is intended primarily for presentation to a human user," which sounds pretty presentation-oriented to me! Didier replies: Good point. What are the underlying operations we can do with a link? a) aggregate b) replace c) move to d) any other idea? Len lead me to the idea that maybe we need an hyperlink algebra like the relational algebra already has. I think that links are intrinsically linked to an operation. Maybe we can say that a link is an operation - involving external content - to be performed by an agent. What we need though, is to explicitly specify these operations. Reading again the xlink specs it is clear that the intent was for rendetion to human beings (or ETs :-) ) since several keywords have a rendition connotation. Cheers Didier PH Martin
