[Zope-dev] Re: [cadaver] cadaver and zope

[Patrick Collins]

Mathieu,
   I may get into an argument with the Zope authors on this one, but in
my opinion, 
they haven't implemented the <link> in the way most clients would
expect.

>From my reading of RFC2518, in order to edit "index_html" (in your
example) the client (cadaver) should be able to GET AND PUT
"index_html/document_src". 

It doesn't make sense to me that you'd read from
"index_html/document_src" and then write back to "index_html". This is
because index_html MAY actually be generated by multiple source files.

The example in RFC2518 in section 13.10.1 seems to behave the way you,
Mathieu, would prefer it to work.

The spec states:
   "The source of the link (src) is typically the URI of the
    output resource on which the link is defined, and there is typically
    only one destination (dst) of the link, which is the URI where the
    unprocessed source of the resource may be accessed."

I've tried to send this email to the appropriate Zope mailing lists but
not sure if I got the right ones.

I'f I'm wrong, I'd be happy for someone to explain it to me because I
will have to implement this into PerlDAV's "dave" command-line client as
well and would rather do it right once.

Regards,
Patrick.
