Nature New Tech - Connotea and Urchin - social bookmarks and RSS aggregator

In an OpenURL mailing list, Tony Hammond ([email protected]), from the New Technology part of Nature Publishing Group says

I just wanted to introduce NPG's new bookmarking tool for scientists - Connotea (http://www.connotea.org/). This is a free service and is being run on an experimental basis - in much the same way as the Urchin RSS aggegator (http://urchin.sourceforge.net/) has been made available. We just added a couple new features last week and are now looking to promote it further.  Any ideas on how to advertise this service more widely to the general scientific community would be gladly appreciated. For example, how to make it known to both students and faculty? One of the challenges I guess for us - and for the library community itself - is how to educate folks to make effective use of this new breed of tool. We also need their input in steering the onward development of what effectively is a web-based citation manager.

I dunno if the mailing list archive is online, anyway there's info on how to subscribe to it at library.caltech.edu/openurl/

I have posted about Connotea previously.

It seems to me that for one the New Technology group needs a better communication method.
There is a site nurture.nature.com but there's nothing new on it since 2003.
There is the Nature Publishing Group page but it's packed with too much info.
For example, did you know that Nature has a toolbar for IE?  I didn't.

Urchin is new to me, the description reads:

Urchin is a Web based, customisable, RSS aggregator and filter. It's [sic] primary purpose is to allow the generation of new RSS feeds by running queries against the collection of items in the Urchin database. However, other arbitrary output formats can be defined and generated using XSL transformations or HTML::Template templates.

In other words, the collection of Urchin Perl modules form a foundation for building an RSS aggregation or portal service.

Urchin also includes code to help administrators import RSS-like data from non-RSS sources. Currently there is code to create RSS objects using regular expression based scraping of text files or SQL queries to Perl DBI sources.

There is also a module supporting the PRISM metadata standard.

I only discovered that by reading a news release NPG Announces Latest RSS Newsfeeds.
