stonesignal
The stonesignal package provides a server for receiving and storing location
data from devices.
Features
- Accept location data from devices using a trivial JSON and/or CBOR API.
- Complete audit log; every operation that changes the state of the system is logged in an append-only log.
- Fully instrumented with OpenTelemetry.
- A small, easily auditable codebase with a heavy use of modularity for correctness.
- An extensive automated test suite with high coverage.
- Platform independence. No platform-dependent code is included in any form, and installations can largely be carried between platforms without changes.
- Extensive documentation including information on installation, a setup tutorial, a theory of operation, maintenance and monitoring information, information on security properties, and full API documentation.
- OCI-ready: Ready to run as an immutable, stateless, read-only, unprivileged container for maximum security and reliability.
- OSGi-ready.
- JPMS-ready.
- ISC license.

Development Snapshots
At the time of writing, the current unstable development version of the package is 1.0.0-SNAPSHOT.
Development snapshots may be available in the Central Portal Snapshots repository. Snapshots are published to this repository every time the project is built by the project's continuous integration system, but snapshots do expire after around ninety days and so may or may not be available depending on when a build of the package was last triggered.
