Who can compare reference sets. 

Users may compare a single reference set across two versions or compare versions across two different reference sets. Which reference sets the user may compare depends on their project access. 

Compare a single reference set across two versions. 

• Non-project members and non-logged in users can only access published versions of public reference sets. 
• Project members may run comparisons on: 
  • Both public and private reference sets within their project. 
  • In development or published versions. 

Compare versions across two different reference sets: 

• Both reference sets must be public or the user must be a member of both projects. 
• Reference sets may be different editions, for example Norwegian vs. US. 
• In development or published versions may be selected.
