Ensuring high quality Resource Metadata is important for easy searching and efficient content management.

Resources are all organised into resource types. The default (out of the box) types are fairly standard and will be relevant in nearly all installations. Differentiating resources by type allows you to record different metadata for different types of assets. Video, image, document and audio types will each require different information to best describe them and make them useful and easily found. Grouping resources by type is a great help in searching as it allows users to simply eliminate large quantities of irrelevant resources to quickly get 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.
