ISO/TC37 standard for time and event markup and annotation. The scope is standardization of principles and methods relating to the annotation of temporal events in the contexts of electronic documentation and language.

Objectives of ISO-TimeML

The goals of ISO-TimeML are to provide a common model for the creation and use of temporal and event annotation, as a means of managing time-related data within documents, and to enable later categorization and data extraction with use of this meta-data.

History of ISO-TimeML

ISO-TimeML was presented to the ISO for consideration as a standard in August 2007. In this presentation, the preliminaries of ISO-TimeML were outlined, and potential applications were examined. In the following year, revisions were made to ISO-TimeML as the standard transitioned from a New Project (NP) to a Working Project (WP). The ISO-TimeML voting period began in October 2008 and was approved as an international standard by March 2009.
