Interoperability isn't just The Law(*), it also enables massive benefits for users, ecosystems and businesses by allowing data to get enriched.

By building on OpenOdin you immediately draw the benefits of application interoperability, user data ownership and automatic data policy enforcement.
OpenOdin is made to scale leveraging SQLite or PostgreSQL as storage backend with no central points of failure and as much redundancy as your use-case warrants.
Run servers in cloud, on premise or any configuration with synchronization in between.
OpenOdin being built as a true decentralized system means it sees everything as a peer but well known roles are supported depending on desired use-case.
Offline first technology is The Hallmark of an interoperable system.
No central points of failure and no gate keepers needed since data permissions lie naturally in the data itself and its associated licenses.
When coming online again synchronization is automatically accomplished and Conflict-free Replicated Data Types (CRDTs) guarantees a smooth data merging.
