org.apache.stanbol.enhancer.servicesapi.ContentSource
The content source representing the data and optionally the media type and file name. This interface is only used to parse the content when creating a {@link ContentItem}. To obtain the content of a ContentItem the {@link Blob} interface is used
NOTE that {@link #getStream()} can typically only be called a single time.Multiple calls will throw an {@link IllegalArgumentException}. @see Blob
