In general, you will need a vocabulary that helps you describe the dataset that contains your data, to facilitate the discovery of the dataset. In this case, you should look for vocabularies that describe as precisely as possible a dataset or your specific type of dataset. For example, in the Agrisemantics Map of standards, you can search for vocabularies that describe ‘Information resource metadata’ (generic vocabularies, for any type of resource) and you would already find vocabularies like Dublin Core or schema.org that are understood by many tools and can encode metadata like title, author, subject, format, spatial and temporal metadata etc.
