Hi @emily.gill 
Totally agree with you regarding the need for actually detailing what interoperability looks like for the user/system - we MUST get better at defining our requirements before we ask the vendors to implement the ‘solutions’.
I agree that a good start (you have to start somewhere) is a commitment from vendors - and I’d argue it needs to be current and future/proposed - towards interoperability by way of sharing data AS coded data (and not text/pdfs/application specific codes).
For the whole system to work, the whole system has to work!!
