If you can't get people to add the ALT tag for owner, then that is quite
a pickle! What are you going to try, a UID<->Name mapping?

I am doing something like that in python. I am towing the line on the
Aliweb architecture (more specifically, the IAFA templates), but am using
my own internal code. There will still be a site.idx file for Aliweb to
look at. More on what I'm doing below.

As of today, it should be fixed. Martijn is implementing mirrors and
local search capability.

I have *really* been looking at it. Here's a snapshot of what I'm doing.

I have a library of classes that implement HTML tags. These tag
instances have attributes like owner, which (right now) I am only
comparing against the REMOTE_HOST. Then, I have a python CGI script that
reads in the site.idx file, creating a dictionary of IAFA template types
(SITEINFO, ORGANIZATION, DOCUMENT, USER, etc.) Each dictionary value is
a list of all the templates in the site.idx file that has that

So, I can now send methods to this dictionary object -- search, edit,
etc. All HTML is constructed from entity class instances -- the title,
owner, etc objects go into a head object, the paragraphs, anchors, lists
go into a body object. Head and body go into a document object, and I
then just say document.render(), and out comes a bunch of HTML.

The WWW client that sends it has to match the .owner attribute on
that object. This allows remote editing of the templates. Finally, I
have a function for printing a site.idx file (conformant to what Aliweb
is looking for) from the dictionary object in memory.

I'd like to add that the system (without implementing the choices for
enhancement) is *very* fast.
