Metadata feedback from Øystein

Generally this looks good, but there are some details to be commented and some to be fixed.

1. I dont understand your comment on the UUIDs. There is an id in the file that we will get when retrieving this information (see attached file). So that aspect works fine for us.
2. keywords, please add the relevant keyword prefix for each keyword you add. We use that to tie keywords to the appropriate vocabularies and in the future the ability to translate between vocabularies. Preferably modify your keywords_vocabulary to something like: :keywords_vocabulary = "GCMDSK:GCMD Science Keywords:" ; I don't have the URL at hand now but can send that later. Then you modify keywords to: :keywords = "GCMDSK:EARTH SCIENCE > CRYOSPHERE, ..." Please beware that some of the keywords you use come from a different GCMD vocabulary so need to add more prefixes. I can look into better feedback on that later.
3. License is a bit too short. Change to something like (depending on your choice): :license = "https://spdx.org/licenses/CC-BY-SA-4.0.html(CC-BY-SA-4.0)" ;
4. Your activity type has to be written as in the https://htmlpreview.github.io/?https://github.com/metno/mmd/blob/master/doc/mmd-specification.html#activity-type otherwise it is ignored (controlled vocabulary).
5. If possible to add iso_topic_category that is good, although not critical for the time being.
6. If possible add dataset_production_status (https://htmlpreview.github.io/?https://github.com/metno/mmd/blob/master/doc/mmd-specification.html#dataset-production-status-types ) to indicate status of the dataset. If In Work, then end time can be left empty.
