In order to assure good metadata quality, projects and institutions using SENSOR are requested to nomminate a chief editor. The role of the chief editor is:

• Identify and document best practices for using SENSOR (agreed in the team of chief editors) and creating metadata in the context of a given institute and/or project
• Organize tutorials for editors in their institute and/or project on a regular basis
• Notify editors about new functionality released in SENSOR
• Periodically control the items created and modified by editors of the own institue/group stored in SENSOR for correctness and completeness and notify editors accordingly
• Move items to "construction" state
• Delete items 

Last two point should be more specific to describe why and how.

There are dicussions in building expert groups for specific devices (DAM and beyond). Also if we have chief editors at the institutes the may/should have inter-institute responsibility.
