As metadata are shared between national and international repositories it is becoming increasing important to be able to unambiguously identify and refer to specific records. This is facilitated by including an identifier in the metadata. Some mechanism must exist for ensuring that these identifiers are unique. This is accomplished by specifying the naming authority or namespace for the identifier. It is the responsibility of the manager of the namespace to ensure that the identifiers in that namespace are unique. Identifying the Metadata Convention being used in the file and providing a link to more complete metadata, possibly using a different convention, are also important.

The combination of the "naming authority" and the "id" should be a globally unique identifier for the dataset. |

1 | Metadata_Conventions | This attribute should be set to "Unidata Dataset Discovery v1.0" for NetCDF files that follow this convention. | ||
0 | Metadata_Link or metadata_link | This attribute provides a link to a complete metadata record for this dataset or the collection that contains this dataset. This attribute is not included in Version 1 of the Unidata Attribute Convention for Data Discovery. It is recommended here because a complete metadata collection for a dataset will likely contain more information than can be included in granule formats. This attribute contains a link to that information. |
Text searches are a very important mechanism for data discovery. This group includes attributes that contain descriptive text that could be the target of these searches. Some of these attributes, for example title and summary, might also be displayed in the results of text searches.

This basic extent information supports spatial/temporal searches that are increasingly important as the number of map based search interfaces increases. Many of the attributes included in this spiral can be calculated from the data if the file is compliant with the NetCDF Climate and Forecast (CF) Metadata Convention.

Describes a simple latitude, longitude, vertical and temporal bounding box. For a more detailed geospatial coverage, see the suggested geospatial attributes. Further refinement of the geospatial bounding box can be provided by using these units and resolution attributes. Many of these extent attributes are calculated using the CF-Conventions. |
