ORNL DAAC Request for New GCMD MimeType keyword: application/yaml

Hi,

Please help to add a new GCMD mimetype keyword.

Mimetype: application/yaml

Definition: YAML (YAML Ain't Markup Language) is a serialization format. It is a strict superset of JSON, with the addition of syntactically significant newlines and indentation, like Python. Unlike Python, however, YAML doesn't allow literal tab characters for indentation. It is designed to be human-friendly and work well with modern programming languages for common everyday tasks. It is broadly useful for programming needs ranging from configuration files to Internet messaging to object persistence to data auditing. Together with the Unicode standard for characters, it is also well-suited for internationalization.

Please let me know if you have any questions or need additional information.

Thanks,
Yaxing

Hi @GCMD - tstevens ,

Yes, we do need a keyword to be added to the MimeType vocabulary. Data Format and MimeType are separate elements of UMM and they refer to the GCMD dataformat and mimetype vocabularies correspondingly.

Best,
Yaxing
