The main aim of JIS (Joint Information System) is to overcome the present lack of detailed knowledge amongst the European Solar Physics community. This lack of knowledge occurs at several levels: groups of researchers, institutions, scientific activities, running programs, resources, new opportunities, observational campaigns etc. JIS will not be data archives -- this is the aim of EGSO, but will provide all information mentioned above collecting all possible data about the institutes and scientists working in the field of solar physics. All European solar physicists will be provided with this information by means of an easy accessible webpage including different inquiry modes (query by country, university, institute, scientist and area of research). Until now such a system did not exist in Europe, but in foreseeable future a user-friendly and logical structured webpage will take on this task.
