RewriteFilter is a servlet2.3-compatible filter able to be plugged in any existing Web application that makes the application better indexed by search engines. It rewrites all generated pages transparently, encoding the URLs. When the filter gets a request, first it analyzes if the request is encoded, then it decodes it and forwards the control to the decoded URL.
C-Cramp (the C-Cramp College Radio Audio Management Program) is a Web-based frontend to MySQL for managing the types of things that small radio stations might need: audio files, data, and "metadata"; DJ and staff information, schedules, live music and program logs, and all sorts of other data. Currently, a cross-platform PHP application is the focus of the project, but more features and types of programs are planned that will hopefully enable easier playback, storage, loading, and entering for all types of applicable data.
MKSearch is a metadata search engine that indexes structured metadata in Web documents instead of free text in the document body. The data acquisition system conforms to the Dublin Core metadata in HTML recommendations, and supports other application profiles, such as the UK e-Government Metadata Standard. It also indexes native RDF formats, including RSS 1.0. The system has five major components: a Web crawler, an HTML document validator and formatter, a set of custom indexers, an RDF storage and query system, and a public query interface, provided through a standard servlet container.
