Ensuring high quality Resource Metadata is important for easy searching and efficient content management.
If you haven't already, Read the Concepts
All resources are organised into resource types. The default, pre-installed types are very general and will be relevant in nearly all installations. Separating resources into types allows you to record different metadata for different types of assets. For example, video, image, document and audio types will each require different information to best describe the the resources and to make them useful and easily found. Grouping resources by type makes searching simple and efficient as it allows users to quickly eliminate large quantities of irrelevant resources and get directly to what they need.
Resource Types should be allocated with care because they each contain different sets of metadata fields most appropriate to the resources within them. Assigning an incorrect resource type may result in information relevant to a resource not being added. As a Resource Administrator you will need to decide how best to arrange the metadata in the system across the resource types.
Use of the Global resource type is important to keep your metadata as organised as possible. The Global resource type is a place to record all the metadata fields that are common to all resource types, such as title, an upload date or a usage license.

Consideration also needs to be given to the upload process to ensure that your contributors are not having to spend several minutes filling out an extensive upload form.
A note on the Allowed Extensions option
If you choose to configure allowed file extensions via the option within the resource type edit screen, if using the upload then edit functionality be aware that the uploader will collate all the allowed extensions to make a single list, applicable to all resource types. This is to allow any of your allowed extensions to be uploaded and then passed on to be edited.
If you leave any of your resource types without set allowed extensions, this will permit any extension to be uploaded via the uploader. To circumvent this, either set allowed extensions for the types without set extensions or remove the resource type if it is not required.
