URML (open robot intent language): a validated intent layer above S-CORE, and an ara::com binding — request for comment

[idoco2003]

Hi Eclipse S-CORE community,

URML (urml.dev) is a small, Apache-2.0 language for describing robot intent: it validates a request against a capability manifest and a safety envelope, then dispatches to the substrate below. S-CORE is the open, service-oriented, AUTOSAR-Adaptive-aligned SDV core URML's AUTOSAR work targets, so let me be upfront about the layer: URML sits above S-CORE as a typed, validated intent vocabulary, not as a competing platform.

Nothing here asks S-CORE to adopt, host, or maintain anything. This is a request for comment.

The mapping I shipped (urml.dev, RFC-0019):

• A declared program can carry an ara::com binding (a service / instance / method id triple). call_program(name, args) is the verb; the validator checks the binding is complete and the args match the declared signature before dispatch. URML adds no AUTOSAR-specific primitive: service-method invocation rides the existing call_program, which is the substrate-neutral discipline URML holds itself to.
• A deployment's cyclic Execution-Management timing maps onto URML's realtime block (RFC-0016): MinimumCycleTime -> cyclic_period_ms, WatchdogTimeout -> watchdog_ms. URML never claims to enforce hard real-time; the field is a descriptive, internally-checked declaration.

Two real questions: (1) Is call_program plus an ara::com id triple the right granularity to name an S-CORE service method from an outside intent layer, or is a different handle more natural in your model? (2) Does mapping Execution-Management timing onto a descriptive realtime block (period + watchdog, no enforcement claim) read as honest from your side?

Thanks for S-CORE; an open, safety-minded SDV core built in the open is a genuinely good thing for the field.
