Harava
Harava is an aggregation and validation system for semantic web metadata. It is currently suitable for processing HealthFinland document-oriented metadata and ActivityFinland event information.
Harava collects semantic information (RDF, RDFa, Dublin Core HTML metadata etc) from web sources, validates it according to a chosen schema, and produces a clean RDF output file that can then be used and stored in a content management system or other data repository.

Publishing information about upcoming events such as concerts and discussion group meetings in a structured format allows the event information to be aggregated, filtered and delivered to potential participants. Making automatic personalized recommendations about events requires structured metadata such as machine-understandable locations and semantic descriptions about the topic and audience of the event. We present a survey of the state of current semantic representation formats for events, including iCalendar and its RDFa and microformat representations, and show that their support for expressing rich structured metadata is limited. We have also tested how well different tools support and understand the formats. Based on the surveys we have implemented a rich event information schema for a health-oriented activity portal and developed an aggregation and validation tool for gathering and processing event information.
