The FOPPA database (French Open Public Procurement Award notices) is a database constituted in the framework of the ANR DeCoMaP project (ANR-19-CE38-0004). It contains public procurement notices published in France from 2010 to 2020. It relies on a subset of the TED database. These data have a number of issues, the most serious being that the unique IDs of most involved agents are missing. We performed a number of operations to solve these issues and obtain a usable database. These operations and their outcomes are described in detail in the following technical report: L. Potin, V. Labatut, R. Figueiredo, C. Largeron & P. H. Morand. FOPPA: A database of French Open Public Procurement Award notices, Technical Report, Avignon Université, 2022. ⟨hal-03796734⟩ The report also describes the database itself.
