Sometimes data is not enough, and we need metadata : we want to know how and by whom it has been produced, altered, updated.
We also want to track history of the data, be able to go back in time, and even sometimes deal with different versions of the same data.
There are numerous technical solutions to cover these needs. We will present some opensource solutions and the associated ecosystem : PostgreSQL mechanisms (triggers), qgis-versioning, pg-version, fastversion and others.
We will speak about different possible use-cases for data versioning and which technical solution is the most adapted, from simple data timestamp to full-fledged history needs.
The talk will be illustrated with some real-world cases.

Engineer at Oslandia since 2016 and historically a full-stack developer, my main area of interest are:
- 3D Gis application in the browser (webgl)
- And everything you can do with PostgreSQL and PostGIS.
Vincent Picavet is an applied mathematics engineer. After a few years working on satellite imagery, he dedicates himself to GIS, designing and implementing spatial data infrastructures with PostGIS. Vincent regularly talks at international conferences, PGConf, FOSS4G or other GIS events. He founded Oslandia in 2009, providing services in opensource GIS.
