Since May 2019, data “Request of Flow Values” (DVF) is available in open-data. The **DGALN** and **Cerema** propose “DVF+ open-data”, which allows free access to the same data in the form of a geolocated database easily exploitable for the observation of land and real estate markets**. The structuring of the proposed DVF data is based on the **shared data model called “DVF+”**, resulting from the work carried out at the initiative of the **national DVF group** and which has been in existence since 2013. This model, developed to facilitate analysis, provides a table of mutations in which each line corresponds to the information and location of a transaction. Geolocation is based on the various vintages of the computerised cadastral Plan also available in open-data. Each of the variables in the DVF+ model is calculated solely from the raw data of DVF. The calculated variables apply throughout the territory and are subject to a shared methodology. There is no exogenous data at this stage except geolocation data from the PCI Vector. Note that the DVF+ model is also the basis for the creation of the database [DV3F](https://datafoncier.cerema.fr/donnees/donnee-dv3f).

This dataset provides open access to "DVF+ open-data", a geolocated database of real estate transaction data derived from the French Request of Flow Values (DVF) records, published jointly by DGALN and Cerema since May 2019. Built on the shared DVF+ data model developed since 2013 by the national DVF group, it structures each transaction as a record with location and transaction details, geolocated using successive editions of the computerised cadastral plan (PCI Vector). All variables are calculated solely from raw DVF data using a shared national methodology, with no exogenous data beyond geolocation. It also underlies the related DV3F database, and is useful for observing land and real estate markets across France.
