14. Issues External interface ICDs (see previous slide)
Ordering / catalogue requirements to be clarified: which missions?
Baseline for HMA specifications
Catalogue: assumed to be GSCDA/EO-DAIL compatible, thus not the latest HMA-FO specification.
Ordering: same assumption although I62.2 requires latest HMA-FO specification.
