September 2018: LSI-VC has had no MRI task lead since last year, and only bilateral activities are ongoing. There is a broad spectrum of definitions of "interoperable". An agreed and documented definition is needed. It was agreed that an action to formalise what we mean by "interoperable" is necessary before further work can be done on VC-30. A new task will be established in the 2019-2021 CEOS Work Plan to do this, and the due date for VC-30 will be changed to Q4 2019.Early 2018: This is underway within the MRI team. LSI-VC members are represented in the group.
