I'm using ml-gradle plugin to deploy the data and modules to a ML10 database. I have used mlModulePermissions property to set permissions for modules.
Is there a similar property to set permissions for the files loaded from ml-data directory?
There is an equivalent property for data permissions:
mlDataPermissions Comma-delimited list of permissions (role1,capability1,role2,capability2,etc) assigned to each document. No default value (which typically means you'll get rest-reader/read and rest-writer/update as permissions on each document).
