Example of interoperability validation on real time with PDL services

Workflow that exemplifies the use of PDL (parameter description language) descriptions for rest services. The web service provides a VOTable that is processed according to the PDL description. Some of the columns in the votable are provided as output in the artifacts (smartVORest config). To check interoperability we have to validatate the connections between outputs and inputs of the artifacts.

In this case, there is an error in the connections. dec output is connected to dec input but dec output is also connected to ra input. As they have different metadata, the validation report shows warnings for these connections (a mismatch in the metadata).
