	TagOwner = "owner"

	ScopeUser         = "user"
	ScopeOrganization = "organiz
    
func MutateTags(userID uuid.UUID, tags map[string]string) map[string]string {
	if tags == nil {
		tags = map[string]string{}
	}
	_, ok := tags[TagScope]
	if !ok {
		tags[TagScope] = ScopeOrganization
		tags[TagOwner] = ""
	}
	switch tags[TagScope] {
	case ScopeUser:
		tags[TagOwner] = userID.String()
	case ScopeOrganization:
		tags[TagOwner] = ""
	default:
		tags[TagScope] = ScopeOrganization
		tags[TagOwner] = ""
	}
	return tags
