Identifies the logical format used in writing a data volume, such as ANSI, TAR, or BACKUP for tape volumes and ISO-9660, HIGH-SIERRA, for CD-ROM volumes.
Provides a unique identifier for a data volume. Example: MG_1001.
Contains the name of a data volume. In most cases the volume_name is more specific than the volume_set_name. For example, the volume_name for the first volume in the VOYAGER IMAGES OF URANUS volume set is: Volume 1: Compressed Images 24476.54 - 26439.58
Provides a full, formal name that describes a broad categorization of data products or data sets related to a planetary body or a research campaign (e.g. International Halley Watch). A volume series consists of one or more volume sets that represent data from one or more missions or campaigns. For example, the volume series MISSION TO VENUS consists of the following three volume sets: MAGELLAN: THE MOSAIC IMAGE DATA RECORD MAGELLAN: THE ALTIMETRY AND RADIOMETRY DATA RECORD PRE-MAGELLAN RADAR AND GRAVITY DATA SET COLLECTION
Identifies a data volume or a set of volumes. Volume sets are normally considered as a single orderable entity. Examples: USA_NASA_PDS_MG_1001, USA_NASA_PDS_GR_0001_TO_GR_0009
Provides the full, formal name of one or more data volumes containing a single data set or a collection of related data sets. Volume sets are normally considered as a single orderable entity. For example, the volume series MISSION TO VENUS consists of the following three volume sets: MAGELLAN: THE MOSAIC IMAGE DATA RECORD MAGELLAN: THE ALTIMETRY AND RADIOMETRY DATA RECORD PRE-MAGELLAN RADAR AND GRAVITY DATA SET COLLECTION In certain cases, the volume_set_name can be the same as the volume_name, such as when the volume_set consists of only one volume.
Identifies the version of a data volume. All original volumes should use a volume_version_id of 'Version 1'. Versions are used when data products are remade due to errors or limitations in the original volumes (test volumes, for example), and the new version makes the previous volume obsolete. Enhancements or revisions to data products which constitute alternate data products should be assigned a unique volume id, not a new version id. Examples: Version 1, Version 2.
