ISO/IEC 14977:1996 Information technology — Syntactic metalanguage — Extended BNF

In the world of programming languages and data formats, defining syntax precisely is crucial. This is where ISO/IEC 14977:1996 plays a vital role. It provides a formal system for expressing the grammar of programming languages, communication protocols, and document formats using the Extended Backus-Naur Form (EBNF). In this blog, we’ll explore the purpose, structure, and importance of this standard in the information technology domain.

What is ISO 14977:1996?

ISO 14977:1996 is a standard for the description of computer programs. It is known as the “Syntactic Metalanguage” or “Extended BNF.”

ISO 14977:1996 provides a common language for describing the structure of computer programs. Thus, It is based on the Unified Modeling Language (UML), which is a standard for describing the structure of objects and their relationships.

Therefore, ISO 14977:1996 is an international standard, and it has been adopted by most major software development organizations. It is also used by many software product certification bodies to certify the quality of computer programs.

The ISO 14977:1996 standard provides a detailed description of the structure of computer programs. So, It can be used to create documentation for computer programs, to validate the correctness of computer programs, and generate code generators for programming languages.

What are the requirements of ISO 14977:1996?

ISO 14977:1996 is a standard that specifies the syntax of the Extended BNF language. In fact, This language is used to represent the structural and lexical rules of formal languages.

ISO 14977:1996 specifies the syntax for a number of different formal languages, including programming languages, theorem provers, and data description languages.

In addition, ISO 14977:1996 is a very important standard, because it defines the structure and grammar of many different languages. It is used by a number of different software applications, including libraries, theorem provers, and data description systems.

If you are working with any type of software that uses ISO 14977:1996, it is important to be familiar with this standard. So, You can learn more about ISO 14977:1996 by visiting the website or by reading the specification document.

What are the benefits of ISO 14977:1996?

ISO 14977:1996 is a standard that defines the grammar and syntax of the Extended BNF language. This language is used to represent data formats in information technology.

The benefits of ISO 14977:1996 include the following:

It facilitates the interchange of data between different applications and systems.

It helps to ensure the correct interpretation of data by other applications and systems.

Also, It makes it easier for software developers to create new applications and systems.

So, ISO 14977:1996 is currently being used by many different companies around the world, including Microsoft, IBM, Oracle, and Google.

Key Features of ISO/IEC 14977:1996
