• *_min vs *_max parameters:
If only one value is available, it must appear in both fields
...
- Mandatory :
publisher - make it mandatory???
add publisher_did as in Obscore (for DaCHS/registry; provides unique ID of service for this publisher/server) - Optional - TBC
spatial_coordinate_description (default = none)
spatial_origin (default = body center or SS barycenter? Or observer location)
time_origin (default = observer)
time_scale (default = UTC – no other values allowed in data services? [only in computational services, e.g. ephemeris])
Same values to be used in registry declaration
• Call-back parameters / reference
Currently using service_title (= schema name) + granule_uid.
May use ivoID in the future.
• Other parameters
The most recent extra parameters often have names starting in prefix_*, where prefix identify the scope or context (e.g., spase_, vims_, image_, etc). Seems to be a good practice.
