TIME-ITEM

TIME-ITEM is an ontology of Topics that describes the content of undergraduate medical education. TIME is an acronym for "Topics for Indexing Medical Education"; ITEM is an acronym for "Index de thèmes pour l’éducation médicale." The ontology, as well as the web application that allows users to work with it, are still under development. Its developers are seeking more collaborators to expand and validate the ontology and to guide future development of the web application.

History
The development of TIME-ITEM began at the University of Ottawa in 2006. It was initially developed to act as a content index for a curriculum map being constructed there. Soon after development began, TIME-ITEM was adopted by the Association of Faculties of Medicine of Canada (AFMC) as the ontology used to metatag assessment objects in qBanq. After its initial presentation at the 2006 conference of the Canadian Association for Medical Education, early collaborators included the University of British Columbia, McMaster University and Queen's University. More recently, it was the subject of a workshop at the 2007 MedBiquitous conference.

Features
The TIME-ITEM ontology is unique in that it is designed specifically for undergraduate medical education. As such, it includes fewer strictly biomedical entries than other common medical vocabularies (such as MeSH or SNOMED CT) but more entries relating to the medico-social concepts of communication, collaboration, professionalism, etc.

Topics within TIME-ITEM are arranged poly-hierarchically, meaning any Topic can have more than one parent. Relationships are established based on the logic that learning about a Topic contributes to the learning of all its parent Topics.

In addition to housing the ontology of Topics, the TIME-ITEM web application can house multiple Outcome frameworks. All Outcomes, whether private Outcomes entered by single institutions or publicly available medical education Outcomes (such as CanMeds 2005) are hierarchically linked to one or more Topics in the ontology. In this way, the contribution of each Topic to multiple Outcomes is made explicit.

The structure of the XML documents exported from TIME-ITEM (which contain the hierarchy of Outcomes and TIME-ITEM Topics) is being developed alongside the MedBiquitous Competency standards. Developers also intend for this document to be compliant with the Web Ontology Language (OWL).

The ontology currently exists in English only but translation to Canadian French is in progress.

Applications
TIME-ITEM is intended to be a general-use ontology for medical education informatics. It has two primary potential applications:
 * 1) Inclusion in curriculum maps.  By mapping learning objects or sessions to TIME-ITEM Topics in a curriculum map, the map becomes searchable for both granular and broad concepts.  If one or more Outcome frameworks are included with the Topic ontology, then the contribution of each curricular element to one or more Outcomes is made explicit.  This also facilitates curriculum evaluation in terms of one or more outcome frameworks.
 * 2) Indexing learning, assessment and portfolio objects.  Metatagging learning objects or assessment objects with a controlled vocabulary enhances the organization and retrieval of objects from a repository.  Metatagging electronic portfolio entries allows one to show how multiple entries "add up" to a demonstration of competence with respect to certain educational outcomes.

The possibility of expanding or modifying TIME-ITEM for use in postgraduate/continuing medical education and in nursing education is currently being explored.
