“The rationale for Universal is web applications such as Phorum, phpBB, WebCalendar, PostNuke, Xaraya, Drupal are unable cooperate because there is no data sharing. Universal is an attempt at bridging these islands of data by providing means for PHP applications written by different people to work better together. As a PHP developer, you can help make PHP web applications interoperate by implementing a shared sign-on mechanism based on the specs described here.”

Xopus as Apache Project?
In a recent post to the Xopus mailinglist, Q42 (the company behind Xopus) announced that they will concentrate on the commercial (closed source) version of Xopus and try to make the open source version an Apache project. While Xopus is an XML WISIWYG editor mainly for the IE Microsoft browser, there’s another XML WISIWYG editor working with Mozilla called Bitflux Editor. We are very excited to see, which of those editors will first become IE and Mozilla compliant, as this might be a decisive aspect concerning their use.
ZZ/OSS implemented Bitflux Editor in oc4ware 0.4.2 as a proof of concept.
ZZ/OSS CTO Christian Zonsius did a comparison of both editors a while ago in the oc4ware mailinglist: http://sourceforge.net/mailarchive/forum.php?thread_id=1137299&forum_id=8231
MotusNet: A Content Network
MotusNet is a content network in which addressable objects, contents, are decoupled from the physical nodes that carry them. The content names in MotusNet are hierarchical, so that they can be aggregated in the routing tables to support a larger number of contents. Further, the process of content replication improves availability, performance, and defends against denial of service attacks by localizing their effect. Additionally, using content migration, similar contents can be placed closer together in order to improve the degree of aggregation. A networking class at Harvard University has built a prototype of MotusNet.

RDF for Libraries
Roger Fischer from bitflux asked me about RDF implementations for digital libraries. Actually, there are almost none. This seems to be due to the fact that RDF is still an evolving technology, thus not used in production environments. Peter Gietz from DAASI pointed me to some interesting documents:
Search Mesh Topology and Visualisation
http://ilrt.org/discovery/2000/09/metamesh/
An Extensible Approach for Modeling Ontologies in RDF(S)
