attribute definition:
property_name
The property name attribute provides a word or a combination of words by which a property is known. -
attribute definition:

The character_constraint attribute limits the characters allowed. -
attribute definition:
valid_minimum
The valid_minimum attribute specifies the minimum valid value in the field or digital object with which the Special_Constants class is associated. Values below the valid_minimum have a special meaning. Values of this attribute should be represented in the same data_type as the elements in the object or field described. -
attribute definition:
pixel_resolution_y
The pixel_resolution_x and pixel_resolution_y attributes indicate the image array pixel resolution (distance/pixel or degree/pixel) relative to the Cartesian (x,y) coordinate system as defined by the map projection. Due to varying properties across different map projections, actual surface distances for an individual pixel may be accurate only at specific location(s) within the image array (e.g. reference latitude or longitude, standard parallels, etc). For most PDS products, x and y resolution values are equal ('square' pixels). The inclusion of both x and y attributes allows for anticipated products where resolution may differ for each axis ('rectangular' pixels). NOTE: Definition of this PDS4 attribute differs from how 'resolution' was defined within PDS3. -
attribute definition:

attribute definition:
maximum_ring_radius
maximum_ring_radius indicates the largest ring radius value in the data table. Units are km and are always positive. Required in label files for ring occultation data. -
attribute definition:
maximum_radial_sampling_interval
maximum_radial_sampling_interval indicates the smallest radial spacing between consecutive points in a ring profile. In practice, this may be somewhat smaller than the radial_resolution because a profile may be over-sampled. If the value of radial_sampling_interval varies, the minimum and maximum attributes are required in labels. Not intended to be used as a table field. -
attribute definition:
element_flag
The element flag attribute indicates whether or not the class is defined as a xs:element in XML Schema. -

The utm_zone_number attribute provides the identifier for the UTM zone. -
attribute definition:
target_type
The target_type attribute identifies the type of a named target. -
attribute definition:
fields
The fields attribute provides a count of the total number of scalar fields directly associated with a group. Fields within (sub) groups of the group are not included in this count. -
attribute definition:
version_id
The version_id attribute provides the version of the product, expressed in the PDS [m.n] notation. -
attribute definition:
name
The name attribute provides a word or combination of words by which the object is known. -
attribute definition:
maximum_value
The maximum_value attribute provides the upper, inclusive bound on the value. -
attribute definition:
maximum_characters
The maximum_characters attribute provides the upper, inclusive bound on the number of characters. -
attribute definition:
start_bit_location
The start_bit_location attribute provides the position of the first bit in a bit field relative to the first bit in the parent packed data field. Bytes are sequential and bits are numbered continuously across byte boundaries within a single bit field. The first bit position in the packed data field is "1". -
attribute definition:
description
The description attribute provides a statement, picture in words, or account that describes or is otherwise relevant to the object. -
attribute definition:
author_list
The author_list attribute provides a list of people to be cited as the authors of the asssociated product. Lists are constructed with last names first and first and middle names and/or initials following. Initials are terminated by periods and delimited by single spaces. Suffixes (if applicable) follow everything else, after a final comma. Hyphenated names may be reduced to initials as "J.-P." Each person's full name is separated from the next by a semi-colon. There is no "and" before the last name. If there is no author list, editor_list must be present and non-null. -
attribute definition:
repetitions
The repetitions attribute provides the number of times a set of repeating fields and, possibly, (sub)groups is replicated within a group. -
attribute definition:
character_constraint
The character_constraint attribute limits the characters allowed. -
attribute definition:
reference_time_utc
reference_time_utc provides a date and time in UTC format. Given in a label when time values in a table are given as elapsed seconds offset from a reference time. Unless there are compelling reasons to do otherwise, reference_time_utc should correspond to the start of a day. Required anytime a table field is given relative to a specific date and time other than when Barycentric Dynamical Time is used (e.g., observed_event_tdb). -
attribute definition:
pattern
The pattern attribute provides a symbolic instruction for forming values. -
attribute definition:
telemetry_source_name
The telemetry_source_name attribute identifies the telemetry source used in creation of a data set. -
