Noting that in the coming week I am not attending the ELIXIR All Hands in Uppsala. Having lived in (and around) Uppsala for more than three years, I am disappointed and with the first stories from colleagues coming in even more. But it has been a way too busy year, I have much to finish up, and I need to take care of myself too. I am not 32 anymore. But in the past two weeks I did attend two workshops.

Some days ago, I started added boiling points to Wikidata, referenced from Basic Laboratory and Industrial Chemicals (wikidata:Q22236188), David R. Lide’s ‘a CRC quick reference handbook’ from 1993 (well, the edition I have). But Wikidata wants pressure (wikidata:P2077) info at which the boiling point (wikidata:P2102) was measured. Rightfully so. But I had not added those yet, because it slows me and can be automated with QuickStatements.

Kasabi is a new, RDF hosting service by Talis. It’s still in beta, and I have been testing their beta service with the RDF version I created of ChemPedia Substances (the now no longer existing cool web service from MetaMolecular to draw and name organic molecules). Kasabi makes the RDF data available via a few APIs, depending on the APIs selected by the uploader. I picked all five of them, just to see how things work.

Last night I upgraded the software behind Chemical blogspace, to the version online on Google Code, though I needed the help from Eaun to get paper titles correctly picked up for ACS journals.

The Blue Obelisk mailing list has seen an interesting discussion on ambiguity in the term ‘open source’, triggered by a study by Beth Ritter Guth. For example, Jean-Claude Bradley performs ‘open source’ science (see his Useful Chemistry blog) who is not opposed to using closed source software, while the Blue Obelisk is about ‘open source’ software.

Chemical Archeology (see Christoph’s comment) is the process of extracting chemical information from old journal articles. Some time ago, Peter Corbett from the group of Peter Murray-Rust visited the CUBIC to talk to us about Oscar3 which can do just that. That day, we already hooked OPSIN into Bioclipse . Oscar3, however, is capable of more then the name2structure of OPSIN (see also 10.1039/b411033a;

R News just released a special issue on the use of the versatile statistics program R in chemistry. It features six articles amongst which one by Rajarshi Guha on the CDK-R bridge, and one by my supervisor and me on the use of self-organizing maps to cluster crystal structures.

We all know chemical space; Chemical blogspace (Cb) is different: it is the chemistry discussed in blogspace. Cb is build on the opensource software of Postgenomic.com which I bloged on before. The now running Cb aggregates 19 blogs and, like the original, extracts linked (cited or reviewed) articles from literature. The system is beta, but I am happy about it already that I mention it now.

After Kalzium and kfile_chemical , KDE has now be extended with kparts for 3D structure and spectrum display: Kryomol . It is written in C++ and licensed GPL. It supports several chemistry formats, among which quantum chemical formats like Gaussian03, NwChem and ACES, and 3D structures as MDL molefile and XYZ.

Derek Lowe is the author of the blog In the Pipeline which is really fun to read. Derek works in pharmaceutical industry and gives a great insight in how things work in that field of molecular sciences. Yesterday he blogged about What Makes an Ugly Molecule? , and touches the Rule-of-Five, the hydrochloric acid bath (aka stomach), and other reasons that make molecules ugly.
