Process

Recommendations should be proposed to the TIH Working Group on ITS Data Definition (WG1). If agreed by that working group and by the registry project team, the recommendation will be passed to the TIH Executive for endorsement. Once endorsed, models will appear on this page.

Recommended Models

The original intention of the registry project was to use the ISO status level of "Preferred" to provide recommendations for ITS data definitions. However, so far no complete model has achieved "Preferred" status - typically due to missing documentation on classes or attributes.

Instead of relaxing the status levels, an additional concept of "recommended" models has been introduced. Models may be "recommended" for particular specified business contexts, with caveats explaining why they have not yet achieved Preferred status. "Recommended" is not a status level. The context for the recommendation is TIH i.e. a recommendation by the TIH Community for use in TIH information services. There is no plan at present to tie recommendations to any notion of compliance.
