After some time of working in a new public spending effort with my colleagues from the National Technical University of Athens, a Linked Open Data portal of public spending has been released. I have contibuted in the part of unifying company names and linking product scheme classifications, neverthless they have performed a very good job promoting to the Linked Open Data initiative a lot of public contracts metadata. See the next video to have an idea of the work:

Hope to continue this fruitful collaboration!
