Subsets Re-activated

The following subsets were re-activated this release. They were previously inactive but have been identified by Canadian implementers as valid pan-Canadian Subsets. As a result, they are active on the Terminology Gateway and have their content validated against the most current version of the Reference Terminology. In cases where Requests for Change (RFC) have been received, those have been applied.

Changes to the Terminology Gateway User Interface

There were a number of changes to the user interface that went live with the April 30, 2018 Subset release. Those changes are:

  1. The default filter for subsets changed from Active to All
  2. Add a new field called "Published On" to indicate the date the subset was published
  3. Add a new field called "Last Reviewed" to inform implementers the date the subset was last reviewed against the Reference Terminology.
  4. The order of the metadata on the Subset Overview tab has been modified.
  5. For all 'Inactive' Subsets, the color of the Subset Status on the Overview Tab has changed from black to red to make it more apparent that the subset is Inactive.
  6. Although the HumanLanguage subset is inactive, it remains visible on the Terminology Gateway with a hyperlink to the SDO that continues to maintain it. Infoway supports the use of HumanLanguage as published by the SDO and will no longer maintain a copy of the concepts on the Terminology Gateway.
