|Still missing from our database was an organised way to present reaction types. Luckily the RSC has a scheme in place to do just that, called RXNO. They even offer an XML file for download with info on all +300 reactions in the inventory. Never mind that the xml file is a clumsy rdf-type, this saves us a lot of effort. From now on, each reaction characterised by an reaction type id and a wikipedia link. In the example below a Horner-Wadsworth-Emmons reaction.
