It is further standardized for USB by the USB Implementers Forum as the ''still image capture device class''. USB is the default network transport media for PTP devices. USB PTP is a common alternative to USB MSC , as a digital camera connection protocol. Some cameras support both modes. The PTP protocol specify a way of creating, transferring and manipulating ''objects'' which are typically photographic images such as a JPEG file. While it is common to think of the objects that PTP handle as Files , they are abstract entities identified solely by an 32-bit object ID. These objects can however have ''parents'' and ''siblings'' so that a file system-like view of device contents can be created. A number of protocols have been developed that extend PTP. PTP/IP, developed by FotoNation and first implemented by Nikon , allows data transfer over a wireless network. Media Transfer Protocol , developed by Microsoft , allows for transfer over wireless or wired networks based in part on FotoNation's PTP/IP, but also allows users to transfer other media aside from pictures, as well as for tagging objects with extended Metadata (such as title, artist and similar).
