Mike released Operator 0.8, which picks up RDF (RDFa en eRDF) from HTML pages, and adds actions to it. I blogged earlier about the beta and wrote a script for it for chemical RDFa . At this moment, Chemical blogspace and RDF for Molecular Space (see this blog ) are using chemical RDFa to semantically markup molecular information.

The new Operator release (download) has one notable API change: it now uses “RDF” as key for semantic information; the add-on now supports eRDF too. So, when installing or updating to version 0.8, you also need to update the Sechemtic user script to version 1.1 or better.

Installing Operator scripts is a bit more work than Greasemonkey userscripts. Save the script to your home directory, or any other place you can easily find on the hard disk. After installing the Operator add-on, click the Options button:

For the RDFa script to work, you need to make sure that the Display style is set to Data formats:

Then you can go to the User Scripts tab, and use the New button to add the script you downloaded and saved to your hard disk earlier:

Then, after rebooting Firefox (looks like MS-Windows :(), you can go to Chemical blogspace and look up molecules, and see output like that described in RDFa Operator in action on Cb.
