RE: RSS data transience and the semantic web

Hi Bob:
 
First off, I would query (like Dan) what the issue of transience has to do
with the semantic web. Isn't this anyway something akin to the Grid which
has very dynamic process set-up and tear-down?
 
But talking specifically to permanence and RSS 1.0, we are maintaining a TOC
archive of our journal feeds - not just supplying the latest feed. E.g. the
current feed for Nature will always be symbolically linked to by
 
 <http://www.nature.com/nature/current_issue/rss>
http://www.nature.com/nature/current_issue/rss 
 
which (this week) is redirected onto
 
http://www.nature.com/nature/journal/v430/n7002/rss.rdf
<http://www.nature.com/nature/journal/v430/n7002/rss.rdf> 
 
If you try plugging in other numbers into the URL you can access the earlier
feeds. At present we just go back to March or thereabouts but we are
considering extending it back to cover all our online issues.
 
We would also like to supply an OpenURL interface (see
http://library.caltech.edu/openurl/Standard.htm
<http://library.caltech.edu/openurl/Standard.htm> ) as a means of providing
a public link syntax for retrieving these feeds.
 
Cheers,
 
Tony

Subject: RSS data transience and the semantic web


What role can RSS 1.0 play in the semantic web considering the transience of
the data? Most data in RSS files today won't be there a month from now, as
the files get updated until today's items fall off the list. Can any
connections that would be useful for a web of information get built from
such data? 
 
It would seem sensible for sites to offer archives of their own RSS feeds,
but I don't know of any that do. (I tried searching for a few at
archive.org, and it never had more than 6 per year for any feed. A
surprising amount of the ones I tried couldn't be stored there because of a
robots.txt exclusion.) Is the application developer expected to archive all
data harvested from crawls? Does anyone know of any applications that are
doing this with RSS data? 
 
Or do we just consider RSS 1.0 to be an RDF application that's independent
of the semantic web? 
 
just curious,
