DocSuite PA is software for document management, electronic registry (protocollo informatico) and administrative procedure handling in Italian public bodies. It covers registration of incoming and outgoing documents, including PEC and e-mail, case files and dossiers, workflows with digital signature, the adoption and publication of administrative acts, transparency obligations and hand-over to a digital preservation provider. It is a web-based solution, written in C# on .NET, that you install on your own infrastructure.
The rights belong to the Italian local health authority AUSL Reggio Emilia, which released the software for reuse under the EUPL-1.2 licence. Dgroove Srl of Villafranca di Verona, Italy, maintains it and sells support, maintenance and development; the source code is published on GitHub. You can run DocSuite PA yourself, so that your documents stay on your own servers. Dgroove also offers it as a cloud service on Microsoft Azure; the hosting region is not stated in the sources consulted. Microsoft is a US company, so the US CLOUD Act may be relevant for that cloud variant.
