User research requests
Research requests enable users to ask admins for help in sourcing resources. Users can fill out a form detailing what they need, and administrators can then help them to find suitable resources. This can be done by either providing them with a list of resources or by sending them links to searches or collections to help them get their search started.
Advanced metadata field configuration
This page covers the advanced options for metadata field configuration including display templates, smart featured collections, display conditions, autocomplete options and additional settings for ExifTool and IPTC metadata.
Edit filters
Edit filters are used to determine if users in a group can edit resources based on the metadata in the resource. The existing 'e0' (or e1, e2 etc.) permissions must be used first to open up edit access.
