The update we released today includes scrapers for the ACM Digital Library and Citeseer. More Scrapers will follow and smaller ones are already included. If you have suggestions for scrapers or already implementations (see last post) we would be pleased to know so.
Additionally we improved the tag editing through the edit link which now appears on every page which shows bookmarks or publications. Since it now also appears on pages which contain resources not owned by you (and therefore you're of course not allowed to change their tags), the page for tag editing shows only the resources which you own. A nice drawback is that now also the download page has an edit link.
At the moment it is possible to select a BibTeX entry on a web page and via pressing the postPublication button inserting it into BibSonomy. The next feature we will release next week allows to extract references from ACM or Citeseer without selecting a BibTeX entry. What we can already provide today is an interface for Scrapers and some helper classes which allow you to implement scrapers for other services. If you are interested in developing a BibSonomy-compliant scraper which we can include into the project, have a look into this JAR-file which contains the source code for the needed classes: scraper-0.1.jar.
