When dragging services onto the authoring tool dashboard, these services should be automatically "piped" together where applicable (i.e. when output from 1 service maps to the input of another service). Leveraging metadata capable of mapping outputs to inputs will facilitate this.
In cases where services cannot be directly piped together, the tool should help identify shim services that can be used. This will require possible extension of metadata around shim services.
If there do not exist shims to assist in piping services together, the authoring tool should help (automatically) generate shim services based on the semantic requirements.
