contains

A physical description of the data store encompasses a description of its gross record structure. This structure consists of one or more PhysicalRecordSegments and their relationships. Allows for the identification of the member and optionally provides an index for the member within an ordered array

isOrdered

If members are ordered set to true, if unordered set to false.

numberOfSegments

The number of segments in a Physical Data Product

overview

Short natural language account of the information obtained from the combination of properties and relationships associated with an object. Supports the use of multiple languages and structured text.

physicalFileName

Use when multiple physical segments are stored in a single file

purpose

An explanation of the purpose of the physical dataset

type

Whether the dataset is a bag or a set: a bag is a collection with duplicates allowed, a set is a collection without duplicates.
