I’ve been using some add-ons for FireFox that enable me to investigate semantic mark-upon any given page if there is any on there. It’s good because it means I can begin to see which sites are all out on Semantic web and which ones aren’t yet. I’m definitely seeing a move towards more of that kind of data though. I thought I’d share with you some of the extensions that I either use now or have used in the past which I found to be useful.
- Semantic Radar: Displays a status bar icon to indicate presence of Semantic Web data in the web page. It recognises FOAF, SIOC, RDFa, DOAP.
- Operator: Lets you combine pieces of information on Web sites with applications in ways that are useful.
- SimilarWeb: Get related articles while reading one and read web comments of sites you are browsing.
- HeadUp: Helps you discover new content and boosts your social networking experience.
- Fuzz: It detects RDFa in any web page.
- Tails: This one detects Microformats in any web page.
- Clear Forest Gnosis: This one is for older versions of FireFox but it uses the OpenCalais infrastructure and locates key information hidden within the text.
These are a nice way to get acquainted with all the semantic code out there. Have fun
