23 Manage Asset Types
Asset types define the data structure and type of data that an asset can store as well as the relationship the asset can have with other assets in the repository. In order for your users to create content items or upload digital asset or business documents to a repository, you must create the appropriate asset types, and then associate them with the repository. You must be a content administrator to create asset types.
In Oracle Content Management asset types are divided into the following two families:
- Content types define groups of data fields of various data types (such as, text type for storing string values, long text type for storing rich-text values, date type for storing date and time values, and reference type for storing references to other assets). For example, you might create a blog article content type, where each asset stores values for title, body, date created, and a list of references to related articles. When you create an asset from a content type, it's called a content item.
- Digital asset types define which file media types (MIME types) assets of that type can store and groups of attributes of various data types to describe the file. For example, you might create a photo digital asset type, including only image/jpeg and image/png file types and attributes for the copyright and a caption. Oracle Content Management includes several out-of-the-box digital asset types—Image, Video, Video Plus (digital asset repositories only), and File. When you create an asset from a digital asset type, it's called a digital asset or a business document.
By default the Asset Types page shows all asset types, sorted by name. Use the drop-down menus on the right to filter by asset type and to change the sort order. You can also use the search box to find an asset type by name.
Note:
If you're using Oracle Content Management Starter Edition, you have limited asset type support:- Includes out-of-the-box asset types for images, videos, and files
- Only 5 custom asset types
To increase the number of assets and take advantage of the full feature set, upgrade to the Premium Edition.
To create asset types you must be a content administrator. After you create an asset type, a repository administrator must associate it with at least one repository so it can be used to create assets in that repository. Repository members with the Manager or Contributor role can create assets from any asset types assigned to the repository.
You can manage asset types in the following ways:
