Merkkauskieltä

Merkkauskieltä, often translated as "marking language" or "tagging language," refers to a class of computer languages used to annotate text or other data. These languages embed special markers or tags within the content itself to describe its structure, meaning, or presentation. The purpose of these tags is to provide additional information that can be interpreted by software, enabling automated processing, display, or retrieval of the data.

A primary characteristic of merkkauskieltä is the use of delimited tags, typically enclosed in angle brackets or similar symbols. These tags can be paired, with an opening tag and a closing tag that bracket a section of content, or they can be self-closing. For instance, in HTML, the tag `<p>` marks the beginning of a paragraph, and `</p>` marks its end. The content between these tags is then understood by a web browser as a paragraph.

Common applications of merkkauskieltä include web development (HTML, XML), data interchange (JSON, YAML), and document formatting (LaTeX). The ability to structure and annotate data makes merkkauskieltä fundamental to many areas of computing, allowing for the creation of rich, machine-readable content. Different merkkauskieli have different syntaxes and are designed for specific purposes, but the underlying principle of using tags to add metadata remains consistent.
