This was a very interesting look at OCLC research.  Thom showed a number of very light-weight coding projects to do a number of very cool and interesting things.  Personally, I liked this one.  Very often, many projects get lost in the complexity of the task.  What I liked here was the research offices efforts to essentially look for smaller, easier way to make things work.  Plus, its got me thinking, would would a one-line openURL resolver in PHP look like J
Generating Recommendations in OPACs: Initial Results and Open Areas for Exploration
Colleen Whitney
This was an interesting talk in light of some of the work being done by John Herlocker at OSU on recommender based systems.  This represented a very different approach to the problem of generating recommendations – in this case, circulation data was being utilized as a seed for generating recommendations.  For me personally, these types of talks were great as OSU is in the process of creating a federated search tool and are starting to look at a couple of issues:
1)       better sorting/relevancy ranking
2)       ways of pushing resources to the user based on system usage.
Anatomy of aDORe
Ryan Chute
“The aDORe Archive is a write-once/read-many storage approach for Digital Objects and their constituent datastreams. First, XML-based representations of multiple Digital Objects are concatenated into a single, valid XML file named an XMLtape. Second, ARC files, as introduced by the Internet Archive, are used to contain the constituent datastreams of the Digital Objects. The software was developed by the LANL Digital Library Research & Prototyping Team and is available under GNU LGPL license.?
