    Notes

    Quad-pattern-level context

    Optionally, quad pattern operations may have a context field that is of type ActionContext. If such a quad-pattern-level context is detected, it will be merged with the actor operation context.

    This feature is useful if you want to attach specific flags to quad patterns within the query plan, such as the source(s) it should query over.

    Install

    npm i @comunica/actor-query-operation-quadpattern
