At the SCC (Steinbuch Centre for Computing) - the scientific data centre of the KIT - we operate a country-wide Sync&Share Service called "bwSync&Share" for Baden-Wuerttemberg since 2014.
This service is embedded in the country-wide Identity federation called "bwIDM" which is operational since 2013.
Both projects were sponsored by the Ministry for Science, Research and Arts in Baden-Württemberg.
Beneath the pure functionality provided by the software the service evolved with processes closely coupled with the bwIDM federation, e.g. provisioning/deprovisioning of accounts, registration based on entitlements, privacy.
Currently 35 Institutions are using this service with about ca. 40.000 accounts.
In 2020 we'll introduce a cost allocation for the institutions using bwSync&Share so the service becomes financially more self-reliant. Thus legal aspects and contracts become very important and we started working on this topic already in 2019. At the moment we also develop the migration of the service to a new software basis.
I may report about some of our experiences operating this service and the legal, financial aspects generated with the transformation to a country-wide service financed by the institutions using bwSync&Share.
