Human Markup Language (also HumanML and, within the context of a HumanML document, huml) is an XML specification developed to contextually describe physical, kinesic, cultural, and social information about instances of human communication.
Development by OASIS began in 2001,[1] and HumanML committee members released a Human Markup Language Primary Base Specification 1.0 in late 2002.
[1] It addresses this purpose by standardizing the presentation of details relevant to communicative acts.
For example, just as Internet users may use emoticons ("smileys") to convey emotional information relevant to their essentially textual communication, HumanML codes the emotional importance and intent of a signal in a series of markup tags.
The standard aims to provide an arbitrarily detailed way to represent information pertinent to any act of communication.
