The present invention relates to a method and a computer system enabling referencing to virtual data and in particular to a method and a computer system for constructing a reference to virtual data. In aspect of the present invention a virtual data argument for virtual data is provided. The virtual data argument comprises a data structure holding: at least one identifier each uniquely identifying one or more items of the virtual data, and at least one descriptor uniquely defining relationship between the item(s) identified by the identifier(s). The present invention is particular useful for indexing data, e.g. frame structures, which are not explicitly represented but constructed during execution of an application, e.g. a web-browser. |
