Abstract

This Recommendation | International Standard provides a standard notation called Abstract Syntax Notation One (ASN.1) that is used for the definition of data types, values, and constraints on data types. <br>This Recommendation | International Standard: <br>&#8211; defines a number of simple types, with their tags, and specifies a notation for referencing these types and for specifying values of these types; <br>&#8211; defines mechanisms for constructing new types from more basic types, and specifies a notation for defining such types and assigning them tags, and for specifying values of these types; <br>&#8211; defines character sets (by reference to other Recommendations and/or International Standards) for use within ASN.1. <br>The ASN.1 notation can be applied whenever it is necessary to define the abstract syntax of information. <br>The ASN.1 notation is referenced by other standards which define encoding rules for the ASN.1 types.
