- This Archie-wais-www has to get around the fact that the doc-id in
- the search response is not the doc-id of the file, it's the id of a
- line in the site listing which refers to the file. However, one
- wants to jump straight to the file, rather than to the site listing.
- For this reason, the gateway throws away the wais doc-id and
- generates an id for the file itself from the headline. If the doc-id
- itself was that of the file (in any format), that would be cleaner of
- course, as the headline could be in any human readable format. [Would
- that be easy, Kean?]

-
- It would be possible, sure. Do we want to have to access an AFTP type
- document just to get a pointer to an FTP site? This takes time, I'd
- prefer top skip that step.

-
- I agree that overloading the database name is horrible! Its a hack to
- show what is possible. You can only do it cleanly if you has
- universal document ids of some form or other.
-
- Sure, clients and gateways can convert UDI formats -- avoids the
- bickering but not as cool as having a common format. (Need that
- smiley again!)
-
- [BTW, If you're going to have an AFTP file format for pointing to
- aftp sites, will you also need a GOPH file format for pointing to
- gopher sites, and a NEWS file format for pointing to newsgroups...?
- Suppose you do have some universal id scheme. Then you could have one
- format for a file of pointers. Using the SES filter system, indexing
- that file could (if it looked like a README for example) retrieve the
- referenced document and index the actual document rather than just
- the name.]
