ExtendsBaseSdmReadiness

Use this node to validate whether a given semantic model extends a base template’s semantic model. Add this readiness check to allow users to validate semantic model lineage before installation using the /app-framework/template/readiness API.

Parameters

Parameter	Definition
`name`	(Required) The name of the readiness check. The result is stored in the app context as `${Readiness.SemanticModelCheck}`.
`sdmId`	(Required) The ID of the semantic model to validate. Usually references a variable, like `${Variables.sdmId}`.
`baseTemplateId`	(Required) The template source ID of the base template whose semantic model the target should extend.
`valueOnError`	(Optional) A map of readiness check names to default boolean values if the check encounters an error.
`condition`	(Optional) An EL expression, evaluated at runtime, that determines whether to run this readiness check or not.

Set runAs to CurrentUser so that this node runs with the permissions of the user installing the app. If you omit runAs, the node runs as AutoProc, a system user.

Note

App Context Values

App Context Value	Definition
`Readiness.<name>`	A boolean indicating whether the SDM extends the specified base template’s SDM (`true`) or not (`false`).

On Failure

Failure handling depends on whether valueOnError is defined:

If no valueOnError is defined, the result is passed through as it is. A failed check returns FAIL_TERMINAL and the chain stops.
If valueOnError is present and the task succeeded, the result is passed through as it is.
If valueOnError is present and the task failed for any reason, the task returns WARN_AND_CONTINUE and passes along the error message. valueOnError is written to the app context so that downstream nodes can continue.
