We present observations within one of the most homogeneous photometric system available, the Geneva seven-colour system. Measurements were employed under the leadership of the Observatoire de Geneve at six different observatories around the world. The filters were identical and the detectors well characterised. In addition, the reduction process is well defined and all the data are processed in a homogeneous way. The disadvantage of such a strategy is that the observed astrophysical objects are prescribed and limited. The last published version of the Geneva seven-colour photometric catalogue dates back more than 30 years. Since then, regular updates have been made public via the General Catalogue of Photometric Data. We present here the newest version (released September 2021), cross-matched with the recent Gaia data releases and the Two Micron All Sky Survey (2MASS) in order to clearly identify the unique identifications of the Geneva working group. This will allow, for the first time, the photometric data to be used in a much more convenient and broader context.
