Edu_RSS Topics
Sept 15, 2003
As promised, more from Edu_RSS. Today we release the Edu_RSS topics page, a set of subject-specific RSS feeds available in multiple output formats (four RSS versions, HTML, Javascript with SOAP and Atom/Echo available shortly). The idea of Edu_RSS topics is that the input from 130 or so RSS feeds is aggregated and organized according to topics. The topics are defoined using Perl regular expressions (but we are also adding SQL topic definition and will use more advanced filtering techniques in the future). Each topic is then output as a separate RSS feed, resulting in a highly filtered but comprehensive coverage of specific topic areas. Please note that this is a work in progress; there are still some glitches in the filtering mechanism, RSS 2.0 produces odd errors, other RSS feeds need proper titles, help is not yet available for SOAP, and the pages still aren't pretty. The purpose of this release is to demonstrate the idea of RSS aggregation and filtering - after all, if we can do this for RSS feeds, we can do it even more easily with learning object metadata or RSS-LOM.
