Semantic Radar is a semantic metadata detector for Mozilla Firefox. Available at Mozilla Add-ons site. It is a browser extension which inspects web pages for links to Semantic Web metadata and informs about presence of it by showing an icon in browser's status bar. Currently it supports RDF autodiscovery (SIOC, FOAF, DOAP and any type) and RDFa metadata detection. New: Semantic Radar can now ping the Semantic Web Ping Service when metadata are detected. This allows for a community based discovery of the Semantic Web data.

This firefox add-on lets you visualize all the RDFa data included in a web page, shows a list with errors and warnings found while parsing the document, and allows to execute SPARQL queries on the RDFa content.

"Semantic Radar is a semantic metadata detector for Mozilla Firefox. It detects the presence of SIOC, FOAF and DOAP as well as generic RDF and RDFa data in a webpage, and displays icons in the browser's status bar when one of these data formats is found. By clicking on an icon the user can browse the RDF data in an online semantic browser. It looks for RDF auto-discovery links generated by data export plugins to discover semantic data."
