I agree that we shouldn't require this to be done by hand.
I did say that in the message you quoted.

Of course. But we do need to make the information mangeable,
otherwise we might as well give up and let full web robots
to it for us.

In Archie you can use directories and tar files to give a context to
information. It is up to the information provider to decide what to
tar up into one file, and where to put it. If all files in FTP sites
were untarred in a single directory Archie would be unusable.
In the Web this is a bit more difficult. _Titles_ of web documents
aren't hierarchically structured like file paths. I suppose the
hierarchical natue of most URL's may help there, but it's dodgy. There
is no concept of grouping like in a tar file, you can't specify "Index
this document but nothing linked from it". This means that additional
info is needed more badly than in Archie.

As I said in the previous message, I am completely happy to leave the
decision of what and how to index up to the person providing the
information, as long as it's done in a standard and parseable way.

ALIWEB index files should (really) be on http://.../site.idx
