Public procurement is quite a specific domain. It is the domain in which public sector and business interfaces, forming business deals that trade public funding for goods and services. It is a huge intersection that, as of 2010, makes up for 17,3 % of the gross domestic product of the European Union (source [PDF]). For example, it amounts almost to 20 billion EUR in the Czech Republic. If I was to use a technical term, then “profiling the EU” might show public procurement as its hot-spot. Therefore, I think that applying linked open data to public procurement in the EU is optimizing where it matters.
