The International Classification of Functioning, Disability and Health (ICF) is a WHO classification for health and health-related issues. In order to foster ICF application in information systems, we devised an implementation profile in ClaML (Classification Markup Language) that allows for representation of ICF subsets and we developed a web-based system for collecting ICF data based on from their ClaML representation. The implementation profile and the application have been tested on 17 subsets, which have been translated into ClaML and then submitted to the web application, to produce test documents.
