  • ...
• Counter-Example(s):
  • Physical Artifact Annotator, who marks physical objects rather than digital data items.
  • Data Scientist, who analyzes annotated data rather than creating annotations.
  • Data Engineer, who processes data pipelines rather than annotating data items.
  • Domain Expert, who provides subject matter expertise without performing annotation tasks.
  • Data Consumer, who uses annotated data items rather than creating them.
