Extensible Markup Language (XML)

Tags: Glossary

A computer term referring to a general-purpose specification for creating custom markup languages, which specifies lexical grammar and parsing requirements. The term 'extensible' is used to indicate that a markup language designer has significant freedom in the choice of markup elements.

What is Extensible Markup Language (XML)?

Extensible Markup Language (XML)

XML, short for Extensible Markup Language, is a computer term that refers to a versatile specification for creating custom markup languages. It provides a set of rules that define how data can be structured and organized in a document. XML is widely used in various industries, including logistics, to facilitate the exchange of information between different systems and applications.

The term "extensible" in XML signifies that designers have the freedom to create their own markup elements. This flexibility allows XML to adapt to the specific needs of different industries and applications. By defining their own markup elements, designers can create a language that is tailored to their requirements, making XML a highly adaptable and customizable tool.

One of the key features of XML is its ability to separate data from presentation. Unlike other markup languages, such as HTML, which is primarily used for displaying content on the web, XML focuses on describing the structure and meaning of data. This separation enables data to be easily shared and processed by different systems, regardless of their underlying technologies.

XML documents consist of tags, elements, and attributes. Tags are used to define the beginning and end of an element, which represents a specific piece of data. Elements can be nested within each other, allowing for hierarchical organization of data. Attributes provide additional information about an element, such as its name or value.

To ensure that XML documents are well-formed and adhere to the specified rules, they must follow certain guidelines. These guidelines, known as the lexical grammar and parsing requirements, define the syntax and structure of XML documents. By adhering to these guidelines, XML documents can be easily validated and processed by XML parsers.

XML has become a widely adopted standard for data exchange due to its simplicity, flexibility, and compatibility with different platforms and technologies. It is commonly used in logistics to exchange information between various systems, such as inventory management, transportation, and supply chain systems. XML enables seamless integration and communication between these systems, facilitating efficient and accurate logistics operations.

In conclusion, XML is a powerful and versatile specification for creating custom markup languages. Its extensibility allows designers to tailor the language to their specific needs, while its separation of data and presentation enables easy sharing and processing of information. XML has become an essential tool in logistics and various other industries, enabling efficient data exchange and integration between different systems.
