Abstract

Methods and apparatus, including computer program products, implementing and using techniques for accessing and organizing data items, including items of digital media, such as digital images, video stream, audio stream, text documents and the like. An object model defines a plurality of data object classes, including a media object class for representing items of digital media and a tag object class for representing categories of digital media. A request for one or more data items specifies a search condition. A collection of one or more data objects instantiated from the data object classes is generated, whereby the data objects in the collection represent data items satisfying the search condition. An iterator configured to sequentially access the data items represented by the data objects in the collection of data objects is generated and used to sequentially access the data items.
