Headerrelated

Headerrelated is a term used in information organization and documentation to denote topics that deal with headers in computing and data formats. It is not a formal standard but is used as a category or tag in wikis, knowledge bases, and software documentation to connect articles about headers and header handling across different domains.

In networking and data interchange, headerrelated topics cover the structure and semantics of header fields that accompany payload data. This includes HTTP headers and their fields, email and MIME headers, and other protocol framing headers that identify content type, length, routing, or security policies. In data formats and file systems, headerrelated covers file headers and metadata blocks that precede or describe the main content, such as magic numbers, format signatures, and EXIF or other metadata headers.

In programming and software development, the term also relates to header files that declare interfaces, constants, and types to be shared across source files, as well as to documenting and parsing conventions for headers in documentation pipelines. In document and page layout, the concept can describe header regions such as title headers, running heads, or page headers used for navigation or identification.

As a tagging convention, headerrelated helps users discover content about how headers are defined, parsed, validated, and used across systems. See also header, HTTP header, MIME header, file header, and metadata.
