>                 URL: https://issues.apache.org/jira/browse/BEAM-1192
>             Project: Beam

> In the [Beam Runner AP|https://s.apache.org/beam-runner-api], transforms of interest
to runners are to be identified by URN.
> Currently, Java-based runners use `instanceof` checks to both override transforms and
to implement primitive transforms. This language and SDK-specific behavior should be replaced
by adding these URNs, and checking them.
