- Well, what d'ya know? Thanks, Tim! I guess I'd better get around to
- reading that spec.
- At first glance, it looks like there are two ways of relating one
- document/node to another. First, there is the LINK property in the header
- of the node. There may be any number of LINK elements within the header,
- each one specifies some relationship between the document and some other
- specifed document. Secondly, a relationship can be specified for any
- anchor using the REL or REV attributes. There are currently about 13
- relationship types currently supported. See sections 3.1, 3.6, 3.15, and
- chapter 6 of ftp://info.cern.ch/pub/www/doc/html-spec.ps.
- So, why are people *not* using typed links? Has noone seen the need
- or is everyone else as ignorant as I am? Is anyone out there creating
- such links? Has anyone built support into their client(s)?
- Why are typed links interesting? Well, one way they could be
- immediately useful to me is in printing material from the web. For
- instance, I have been reading about the web, HTML, SGML, HTTP, hypertext,
- etc. The other night I wanted to take a hardcopy of some of the
- documentation home with me, but I had to print it node by node. (I did
- find the postscript documents available via ftp, but they just aren't
- as current or complete as the material on the web.) If the links were
- typed, and my client was smart enough, I could ask for a printout of
- the current node and any anchors within it which are no more than 2 hops
- away and whose type is "embed", "present", or "includes". Depending on
- the particular node that I was at, this should get me a manageable amount
- of information relevant to my current interest.
- Of course, there are some design issues involved in deciding how to
- display/present the results of such directives.
