Projects / Informa


The Informa RSS Library provides a convenient Java API for handling news channels and metadata about them. Different syntax formats (like RSS 0.91, 1.0 [RDF], 2.0, and Atom 0.3) for feeds are supported. There is also basic support for channel information descriptions (OPML). A full-text engine (Lucene) can be used for indexing and searching the news items. Two backends for storing the data are currently provided: In-Memory and Hibernate (which allows you to persist news items into allmost any JDBC compliant database).

            Release Notes: This release restructures core interface inheritance through the introduction of MetaInterfaces (MIF), breaking neither the public API nor any implementations.
