Specific Handles are used in the Handle System to represent the prefixes:

•The Handle of a prefix is in the format "0.NA/<prefix>".

•The record of a prefix Handle (record returned by Handle resolution) contains administration data for managing the prefix. For example, 0.NA/10.100 record stores the location (service information) of the LHS responsible for the resolution of DOI names under 10.100 (see also Prefix Handle Example).
