Character Data Representation Architecture Reference
Character Data Representation Architecture (CDRA) is an IBM architecture which defines a set of identifiers,
resources and APIs for the purpose of identifying character data and maintaining data integrity during data conversion processes. The reference publication provides the reader with the framework for the identifiers, descriptions of the supporting resources and APIs, as well as methods for data conversions. CDRA is applicable to
country specific data encodings such as the ISO-8859 series as well as large character sets such as Unicode.
