I do not care about physical and chemical properties in Wikipedia, as I can easily extract them from other sources.\nThe main value of Wikipedia for molecules is, I think, that it describes the history of a molecule. Additionally, the Wikipedia URL is a\nnice unique molecular identifier (for example http://en.wikipedia.org/wiki/Lactose) given certain\nconditions, and many bloggers are using it as such .\nBut, it only is a useful identifier if one (and only one) InChI is stated on the wiki page.

\n\n

Now that I am RDF-ing molecular space , I was\nagain interested in dbpedia, a RDF version of Wikipedia.\nSee these two blog \nitems and Peter’s very nice\ndbpedia, RDF and SPARQL - for chemistry item.\nChristian is picking this up, and extending dbpedia for support for the various chemical boxes.

Wikipedia Templates

\n\n

I have spotted a couple of templates: Drugbox,\nChembox, Chembox new,\nof which the last one seems to most recent, and has extensions for explosives and drugs. The\nWikiProject Chemicals does not mention it though. Anyone who knows the status?\nIs chembox new the way forward and going to replace the older chembox? I hope so, because only the newer one has InChI in\nthe last of official fields. Or is chembox new simply an extension of chembox itself?

\n\n

Somewhere between 1000 and 1500 entries use the chembox new and another 1000 to 1500 use chembox but I assume there is\nconsiderable overlap. Additionally, Christian noted that there still seem to be molecules in Wikipedia which do not use a\ntemplate at all, and counted some 1900 molecules using various lists. If you you want to keep a more close eye on chemistry in\ndbpedia, you should register to the dbpedia-discussion\nmailing list.
