Provision of content to a client device

摘要

Content accessible to a variety of client devices from a web page is associated with machine readable labels setting out capabilities required by a client device in order to manifest the content in a meaningful manner. Several versions of the content may be provided by the author, each version of the content being associated with its own specification of client device capabilities required to manifest it. The capabilities required are matched with the technical attributes of a client device, in order to establish which version of the content to provide to a client device.
