Attributes whose values are not organized in an enumerated list or hierarchy. A standard attribute contains information about a record. An assignment from a standard attribute is known as a standard attribute value (or KVP, key-value pair). Each Endeca record is described by a set of attribute values.
A standard attribute differs from a managed attribute in that it does not have an hierarchy or an enumeration of attribute values attached to it. Standard attributes (along with managed attributes) are intended for display once the end user has searched or navigated to a record set or an individual record. Standard attributes are described by a type of schema records — Property Description Records (PDRs).
