Best Practices
Projects names are important for data search and discovery. In order to provide a consistent search experience, Project names are controlled by GCMD vocabulary maintained in the Keyword Management System (KMS). This is especially important for faceted searches by Project name in the Earthdata Search Client. A list of valid Project keywords can be found here: https://gcmd.earthdata.nasa.gov/kms/concepts/concept_scheme/projects?format=csv
