This table contains the metadata elements recommended for the discovery of data resources. These elements are are identified in Table F.1 of the ISO 19115-1 specification. Each of the element names is followed by an abbreviation to indicate the element obligation and max occurrence. The obligation options include M for Mandatory, O for Optional, or C for Conditional. The occurrence options are 1 or N for any number.
