-This processor is executes RML mapping rules using the Java-based [RMLMapper engine](https://github.com/RMLio/rmlmapper-java). A mapping process can be defined within a Connector Architecture (CA) pipeline, by defining an input stream of RML mappings, which will be executed sequentially. A set of logical sources (`js:rmlSource`) and targets (`js:rmlTarget`) can be optionally declared to make them visible to the CA pipeline. Otherwise a default output (`js:output`) needs to be defined, pointing to a file where all produced RDF triples/quads will be collected.

 Logical sources can be marked as trigger-based (`js:trigger`) to indicate that they will be updated in the future and therefore, triggering new mapping executions. Finally, a path (`js:rmlJar`) to a local RMLMapper can be given. An example definition of the processor is shown next:
