.. _released_chart_compatibility: ***************************** Released Chart Compatibility ***************************** The released ``ska-oso-integration`` chart will be internally consistent, meaning all the OSO applications should work with each other and the ODA. Implicit in this is that all the applications will be using a compatible version of the data model library - the `PDM `_. For more information on these internal dependencies, see :doc:`../general/oso_internal_dependencies` OSO interfaces with the telescope via commands sent to TMC. These interfaces are defined in the `telmodel `_ and are serialised using the `CDM `_. OSO's responsibility is to capture the user's intent in the PDM and transform this into the CDM commands, using the transform functions in the `ska-oso-scripting library `_. This project's pipeline runs automated tests that execute SBDefinitions against a version of TMC with the lower level subsystems in simulation mode. Using the on-demand pipeline deployments, the chart is also often manually tested against a full telescope deployment. Details about versions of the telescope subsystems that these tests have been performed against and any other release notes can be found the REL tickets.
