To use this Template:

  1. Search (or Go to) for a page with name like xxxxx_Artifact_Definition
  2. Click on the RED link to the (previously) undefined page in order to edit it.
  3. Type {{subst::Template:SAIF Artifact Definition}} as the only content for the new page.
  4. Preview (if desired) to verify the reference was typed correctly
  5. "Save" the page.
    At this point, the contents of this template (with the following exceptions) will replace the substitution link. The exceptions are:
    • These instructions will not appear.
    • The small blue-font annotations about each entry will be replaced with an <!-- XML Comment --> saying the same thing. These comments are visible while editing, but they do not appear when the Wiki page is previewed or saved.
  6. Re-edit the page to include the appropriate content in each of the sections
  7. Save again
The displayed contents below this line is the outline for an artifact definition
