RDFaDev: HTML+RDFa development with FireFox

Celso informed me in this old post about an alternative to Operator for RDFa handling in browsers, or Firefox in this case: the RDFaDev add-on. It works quite well, extracts the RDFa, reports common problems, and even allows running SPARQL directly on the web page, all from within a browser pop up window: less than 1 minute read

A new CDK default fingerprinter?

The current default fingerprinter in the CDK depends on aromaticity, but that concept is algorithmically difficult to define, and even experimentally there are multiple dimensions to this concept.

Critical mass for Open Notebook Science wikis by prepopulation with RDF data

One of the problems with Open Data, - Source, and Standards (ODOSOS) is to get critical mass: for the project to move forward, you need both a good user community and an active developers community. The first is the crucial reward for the latter: people using your work is the incentive. Sometimes, a project does not succeed in doing that; Rich was questioning if his ChemPedia project built up enough mass. 2 minute read

All CrystalEye data available as PDDL
