General Purpose, Lightweight, and Content Syndication Markup Languages
This is a partial list of markup languages. The links pointed to are the most authoritative links I could find on each particular markup language. Note that I chose only the more popular markup languages for each category in order to give you an idea of the scope of use of markup languages.
General purpose markup languages
- Generalized Markup Language (GML) - the predecessor of SGML
- Standard Generalized Markup Language (SGML) - a predecessor of XML
- Extensible Markup Language (XML) - Some resources: W3C XML, Cover Pages XML, XML.com
Lightweight markup language - Uses very simple syntax since they are designed for very simple text editors.
Content syndication markup languages - We are very familiar with the first two since it is what’s mostly used for web feeds.
