| the link semantics. Some other issues, including readability by humans have
| been raised.

Two months ago I proposed on this list the usage of an Url:-line in the
auxiliary header in a news.answers posting so that a faq-author can 'bless'
some non-usenet version of the posting. I had noticed that an increasing
number of authors were doing it, in slightly different ways.
There was not much discussion and I think it will make it into the
news-answers/guidelines.

We are currently updating our WWW news-answers archive so that
Url:-lines in news-answers posting are clickable.
The archive is in http://www.cs.ruu.nl/cgi-bin/faqwais.
Only the stuff retrieved via wais in html'ized (and clickable).
We are working on a html index (as available in the ftp-archive).

| I see four substantive issues:
|
| 1) Is the semantics of the link to be "point to *current* version of"? Or
| "point to *longer* version of?". Or "point to *authoritative* version of"?
| Or something else?

News.answers postings are very diverse in nature.
It is VERY important to have as little rules as possible.
Let the author point to any off-usenet piece of info.
If it is html, the author can further point to long-versions,
short-version, update-forms, more than anybody can imagine.

Let's just have an Url:-line for this.

| 2) Should the header be specifically a URL/URN link or a general
| link-to-other-resource header that can take a news article ID?

My feeling is that we should have separate mechanisms for pointers
usenet-posting -> off-usenet info (www-info) and
usenet-posting -> other usenet-posting.
