Using the InChI and the new rdf.openmolecules.net \nwebsite, it is now possible to tag molecules. And if you use Connotea for that, your tags will\neven show up on the rdf.openmolecules.net website. For example, at the time of writing,\nmethane was tagged with alkanes and gas.

\n\n

The trick I use, is that the rdf.openmolecules.net gives every molecule a unique HTTP URL.\nThis simply web2.0 approach offers an enormous amount of possibilities. The simplest application is that you can tag your molecules\nwith a set label, such as my-tomato-set; after all, Connotea is account based. In this way, you can do open notebook QSAR studies (though the activities would still be missing).

\n\n

The aforementioned example, however, give two classifications. Methane is an alkane and Methane is a gas (at room temperature).\nNot very well determined semantics, but it is web2.0, not the semantic web.

\n\n

Interestingly, given some loosely defined semantics, use Connotea to link a molecule to a certain publication. For example,\nI can define Estrone is cited in the article with PubMed ID 15659855 using the\ntag pmid:15659855. I’m sure using the DOI would work too, using the tag doi:10.1107/S0108768104028344.\nI have not used these informal semantics in the rdf.openmolecules.net website yet, but if there is such interest,\nI can have such functionality hacked in minutes.

\n\n

BTW, did anyone see Gene Ontology terms being used in social bookmarking services?\nFor example, seeing a link to the PDB database with a tag go:0008152? Would be a bit cryptic, and, really, in this\ncase rather minimalistic on information.

\n\n

What’s next?

\n\n

Now comes the tedious task of converting the QSAR data sets I used in my PhD research with these tags. It’s really\nsomething I wanted to do for a while now. Next on my TODO list is the\nGreasemonkey script that adds the tags from Connotea to PubChem.
