适用范围：This Part of ISO/IEC 21000, entitled Digital Item Processing (DIP), specifies the syntax and semantics of toolsthat may be used to process Digital Items. The tools provide a normative set of tools that specify theprocessing of a Digital Item in a predefined manner.This technology is specified in one normative clause and three normative annexes:- Digital Item Methods:Digital Item Methods (Clause 5) specifies the set of tools enabling Digital Item Users to includesequences of instructions for adding predefined functionality to a Digital Item. Such a sequence ofinstructions is a Digital Item Method. Digital Item Methods are authored with the Digital Item MethodLanguage (see 5.2) which includes bindings to Digital Item Base Operations (see 5.4). For extendedfunctionality, Digital Item eXtension Operations (see 5.6) allow such processing to be implemented moreefficiently in a higher level programming language. Tools for integrating Digital Item Methods into DigitalItem Declarations are also specified (see 5.3).- ECMAScript bindings for Digital Item Base Operations:Annex A specifies the ECMAScript bindings for the Digital Item Base Operations described in 5.3.- Java bindings for Digital Item Base Operations:Annex B specifies the Java bindings for the Digital Item Base Operations described in 5.4.- Calling Java based DIXOs from Digital Item Methods:Annex C specifies the mechanism for calling Java based Digital Item eXtension Operations. Digital ItemeXtension Operations are described in 5.6.
