How to validate a task to verify conformance of its new and updated concepts to rules for SNOMED CT lexical content patterns and logical structure.


StepsReferences

Either

Press Validate in the Task View - Task Details panel actions button list.

Or

Press Start New Validation from the left-hand button bar Validation sub-menu

  

A "Task successfully submitted for validation" notification is presented in the page header.

On initial submission for validation, the task content branch is locked to prevent any further changes, and a warning notification is presented above the Validate action button in the Task Details panel. Whilst this is present, changes cannot be made to the content saved in the task branch, and action buttons other than Edit Task Details become inactive. The task is typically unlocked for editing within a few seconds.

Whilst validation is running, a status icon is presented in the page header, to the right of the task identifier, and a "Validation Running" notice replaces the request button in the left-hand button bar Validation sub-menu.

Validation takes many minutes to complete

Validation is one of the most computationally intensive activities for the Authoring Platform, so takes some time to complete. Each validation request is placed in a queue for processing by the Release Validation Service (RVF) so completion time can depend on how many are queued as well as the computational performance of the RVF. Completion time can be up to 30 mins, perhaps longer in extreme cases, but is more typically around 10-20 mins.

When the task validation is completed, a header notification is presented which includes a link to the Validation Report containing the validation results.

EITHER

Follow the link in the header notification to open the Validation Report.

OR

Press View Validation Report in the left-hand button bar Validation sub-menu.



The Validation Report is presented in place of the Edit Panel, Concept Diagram and left-hand context panels, with an "Initialisation complete" header notification.

This contains the following:

  • Header bar with
    • Report label showing "Validation Report Completed <date-time-stamp>".
    • Show Full Report text action button.
    • Show Whitelist text action button.
  • Report panel.

If the task contains no validation errors, the message "No validation results to display" is presented in the report panel.

If the task has validation issues then the validation report will contain a listing of validation assertion failures. Each list entry contains:

  • Validation assertion description.
  • Total number of cases (concepts) which failed that assertion.
  • Load Cases icon/text action button.
  • Download icon/text action button.

Press Load Cases  on an assertion list entry to see the concepts which triggered the assertion.

The report panel switches to a tabulated list of concepts below a header line which contains the Assertion Failure text, and a Back to Report  icon/text action button (which returns to the case listing view).

Each concept row has the following:

  • Select box.
  • Concept Id  (SCTID).
  • FSN  term.
  • Error Message.
  • Add to Whitelist text action button.
  • View/Edit Concept icon button.

The table rows can be sorted by Concept Id, FSN and Error Message by toggling the column header labels.

The select boxes on each row work in combination with the Add selected to Whitelist and View/Edit Selected Concepts action buttons in the rightmost two column headers. These actions will be applied to all selected concept rows to quickly process them as a group.

Press Add to Whitelist (on a single concept row) or Add Selected to Whitelist (selected rows) to place assertion cases on the Validation Report whitelist. Whitelisted cases are removed from the assertions failures listing. Such cases can be viewed by pressing Show Whitelist  in the Validation Report header.

Press Hide Whitelist  to clear it from view.

Whitelist scope is global

Note that the whitelist applies to all validation reports, not just the current task/project, so should be used with careful consideration of its impact to all tasks/projects.

Given this global impact, whitelist management needs careful review and should only be done by experienced quality assurance staff.

Press View/Edit Concept  (on a single concept row) or View/Edit Selected Concepts (selected rows) to see case concepts in an embedded Taxonomy/Editor panel below the cases table. This supports direct inspection and editing of concepts on a case-by-case basis without leaving the Validation Report.

To remove a concept from the Taxonomy/Editor panel press its "X" (Remove concept from edit panel) icon button in the concept header icon button list (as for the main Editor view).

Press Download  to save a list file to your local machine in .tsv  format. The file contains the Concept ID (SCTID) and FSN term for each concept in the cases list (one per line, tab-delimited; line 1 is a header line with field labels).

By default the Validation Report shows only assertion failures triggered by concepts modified within the task. Press Show Full Report  to see all assertion failures for the entire branch contents. These may include assertion failures carried into the task from the project level, either on task creation or via task rebase.

When viewing the full report, press Show Task Report  to return to the default view and only present assertion failures triggered by changes made within the task.
