Media assets are assets that typically have content, such as a URL pointing to a Web page, a JSP template, or a block of product copy that is managed by Merchandising. In technical terms, media assets are ATG Commerce assets that are stored in a content repository.
You can work with the following types of media assets:
Media-internal-text assets store blocks of text. For example, a line of text displayed by a slot on your Web site might be stored as a media-internal-text asset.
Media-internal-binary assets store binary files, such as images or PDFs. For example, an image of a product might be stored as a media-internal-binary asset.
Media-external assets store URLs that point to files, such as text or binary files, that are stored outside the catalog database. For example, a JSP template used for all products might be stored as a media-external asset.
You organize media assets in media folders. Media folders are required, that is, a media asset cannot exist outside a media folder. Before you create your media assets, decide how you want to organize them and create an appropriate folder structure.
