XML-based template language for devices and services
First Claim
1. A method comprising:
- creating a device template using a template language written in XML syntax;
defining, from the device template, a device description for a self-describing network device; and
automaticallly evaluating, via a computer software tool, whether the device description is well formed.

Abstract
A universal plug and play (UPnP) device makes itself known through a set of processes-discovery, description, control, eventing, and presentation. Following discovery of a UPnP device, an entity can learn more about the device and its capabilities by retrieving the device'"'"'s description. The description includes vendor-specific manufacturer information like the model name and number, serial number, manufacturer name, URLs to vendor-specific Web sites, etc. The description also includes a list of any embedded devices or services, as well as URLs for control, eventing, and presentation. The description is written by a vendor, and is usually based on a device template produced by a UPnP forum working committee. The template is derived from a template language that is used to define elements to describe the device and any services supported by the device. The template language is written using an XML-based syntax that organizes and structures the elements.

10. A method of describing a a self-describing network device, comprising:
-
storing a description of the self-describing network device, the description comprising a set of elements to describe the self-describing network device and an XML-based syntax that structures the set of elements such that, when the data structure is read by a computing device, the computing device can learn about the self-describing network device;
making the description available to the computing device; and
wherein the set of elements includes at least one of;
a first element to identify one or more versions of a template lenguage;
a second element to identify the self-describing network device; and
a third element to specify a base universal resource locator (URL). - View Dependent Claims (11, 12, 13, 14, 15)
