Abstract: Various embodiments enable a media playback device to present a user with the option to add items referenced in a media object, such as a movie, ebook, song, game, or application, to a wishlist for later purchase or sharing. An example system performs content analysis of the media object to determine which items are referenced in the media object and where they are located within the media object. Further, the system can query an electronic marketplace for more information about which specific types, sizes, colors, or other variations of the item are available, as well as information such as price, shipping cost, shipping time, and so forth. In a video media object, for example, the system can present a custom miniature storefront for various scenes or frames in the video that represents items present or referred to in the scenes or frames.

Abstract: Processing an object that shares a parent with another object is disclosed. An indication is received with respect to an object that shares a parent object instance with one or more other objects that a change associated with the object is to be made to a data comprising the shared parent object instance. The parent object instance is cloned to create a new parent object instance. The new parent object instance is designated as the parent of the object instance.

Abstract: Storing data is disclosed. An attribute is included in a combined set of attributes. The combined set of attributes includes a plurality of attribute values associated with an object and is stored in a single database field that is not specific to any one attribute in the combined set of attributes.

Abstract: Retrieving stored data is disclosed. A retrieval request is received for an object. A retrieval response is generated that includes: 1) a first set of searchable attributes associated with the object, wherein an attribute of the first set of attributes is stored in a database in a manner that enables a database query to be performed against the attribute of the first set of attributes; and 2) a second set of non-searchable attributes associated with the object, wherein an attribute of the second set of attributes is stored in the database in a manner that does not enable a database query to be performed against the attribute of the second set of attributes.

The parent object instance is cloned to create a new parent object instance. The new parent object instance is designated as the parent of the object instance.

Abstract: An attribute of a hierarchical class-based object is received. The attribute in a database is stored both in a first location in a first table at a first level of a hierarchy of database tables which table hierarchy is based at least in part on a class hierarchy associated with the hierarchical class-based object and in a second location in a second table at a second level of the table hierarchy which second level is higher than the first level.

Abstract: Storing data is disclosed. An attribute is included in a combined set of attributes. The combined set of attributes is stored in one or more database locations not specific to any one attribute in the combined set.

Abstract: An attribute is received for storage. Whether the attribute is searchable or non-searchable in storage is determined. Storing the attribute as a searchable attribute comprises storing the attribute in a database table corresponding to a hierarchical class-based object. Storing the attribute as a non-searchable attribute comprises storing the attribute together with one or more other non-searchable attributes as a set of attributes. The set of attributes is stored in a database location outside the database table corresponding to the hierarchical class-based object, and the database location is accessed before the database table. A unique attribute identifier is associated with the attribute to distinguish between a name of the attribute and a name of one of the one or more other non-searchable attributes in the event that the name of the attribute and the name of the one of the one or more other non-searchable attributes are assigned the same name.
