Other properties

Comments:		Activities relevant to scientific knowledge generation including things like designing and performing experiments, data analysis and transfomration, publishing research results, data curation and interpretation, observations of the natural world, and assessment and treatment of patients in clinical settings. These activities produce information that gets encoded in sharable artifacts used to generate scientific knowledge. Agents can play different types of roles in the generation and use of such artifacts.
