I posted several months ago on RSS feeds. This is by way of an update since a number of interesting developments have occurred recently. Firstly, an excellent article detailing some of the standards (and not so standard) evolution in this area is available at http://www.xml.com/pub/a/2003/07/23/rssone.html I strongly recommend that for a balanced overview. What is more interesting is that the examples shown in this article actually relate to chemistry! Thus the Tetrahedron journal is now publishing an RSS feed (the URI for which I have not yet managed to find! Can anyone help?) as is the science journal Nature (http://nurture.nature.com/rss/rss.rdf ) I dont believe any of the learned society publishers have yet adopted this approach, but if anyone spots RSS feeds from them, please tell this list! Secondly, the metadata content of RSS (by default based on DC, or Dublin core) is now being extended specifically for journals using a namespace called PRISM (Publishing Requirements for Industry Standard Metadata ) which contains items such as <prism:publicationName>Tetrahedron</prism:publicationName> <prism:volume>59</prism:volume> <prism:number>28</prism:number> <prism:startingPage>5215</prism:startingPage> Interestingly the overtly chemical content is still carried (and recognised as chemical by humans only!) as <title>New 5-(2-ethenylsubstituted)-3(2H)-furanones with in vitro antiproliferative activity</title> We anticipate its only a matter of time before discrete chemical namespaces appear (such as contained in http://www.xml-cml.org/cml.rss ; see eg the Internet Journal of Chemistry RSS feed at http://www.ijc.com/abstracts/rss.xml, with a reprint of this article at http://www.ch.ic.ac.uk/rzepa/rss/, Part 2 is to be submitted shortly) We should remind ourselves however that in many ways the handling of metadata is still at the stage where the web was around 1993-1994 (although now arguably, the driving force is no longer from the academic environment but from the business sectors!) -- Henry Rzepa.
