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.[2] In the following year, revisions were made to ISO-TimeML as the standard transitioned from a New Project (NP) to a Working Project (WP).[3] The ISO-TimeML voting period began in October 2008 and was approved as an international standard by March 2009.

Current stage

ISO-TimeML as one of the members of the ISO/TC37 family of standards

The ISO/TC37 standards are currently elaborated as high level specifications and deal with word segmentation (ISO 24614), annotations (ISO 24611 aka MAF, ISO 24612 aka LAF, ISO 24615 aka SynAF, and ISO 24617-1 aka SemAF/Time), feature structures (ISO 24610), multimedia containers (ISO 24616 aka MLIF), and lexicons (ISO 24613 aka LMF). These standards are based on low level specifications dedicated to constants, namely data categories (revision of ISO 12620), language codes (ISO 639), scripts codes (ISO 15924), country codes (ISO 3166) and Unicode (ISO 10646).

The two level organization forms a coherent family of standards with the following common and simple rules:

  • the high level specification provides structural elements that are adorned by the standardized constants;
  • the low level specifications provide standardized constants as metadata.
