Data Object Representation
Identification Area• Unique product ID• Authorship• Archive provenance
Observation/Context Area• Observation time• Result description (wave-
length, science discipline, etc.)• Target• Source (mission, observatory,
etc.)
Mission AreaClasses and attributes defined by the data preparer in a local namespace specific to this mis-sion, observing campaign, or similar source.
Discipline AreaClasses from discipline name-spaces containing discipline- specific analytical metadata. For example:• Display Settings provide cor-
rect visual orientation of an image-type data object
• Geometry provides observa-tion geometry
• Spectral Characteristics in-cludes bin definitions for spec-tral observations
• etc.
Reference ListDirect linking to other PDS ar-chive products and to the sci-ence literature via citations with DOIs.
File Area• Identification of data file• Integrity checking information• Repeatable - one product may
comprise several files.
Data Object Representation• Detailed (to the byte level)
physical structure definition• Detailed science definition
(units of measure, field-by-field descriptions where appro-priate, etc.)
• Physically contiguous within the data file
• Multiple different data objects may be included (serially) in the same data file
The Anatomy of a Data Product Label
The sequence of attributes, classes, and label sections is defined and validated by the PDS schemas, resulting in uniform structure, sequence, and naming across labels from all sources.
