Abstracted device service discovery

Abstract

Methods and devices for device service discovery may include receiving a query for a device service including one or more protocol-specific services connected to or discoverable by a computer device. The methods and devices may include mapping the query to one or more protocol-specific adapters selected based on the protocol-specific services. In addition, the methods and devices may include identifying at least one device endpoint representing at least one device that supports the device service and generating a list of device endpoints and corresponding service properties for each device that supports the device service.

What is claimed is: 
     
         1 . A computer device, comprising:
 a memory to store data and instructions;   a processor in communication with the memory; and   an operating system in communication with the memory and processor, wherein the operating system is operable to:
 receive a query for a device service including one or more protocol-specific services connected to or discoverable by the computer device; 
 map the query to one or more protocol-specific adapters selected based on the protocol-specific services; 
 identify at least one device endpoint representing at least one device that supports the device service; and 
 generate a list of device endpoints and corresponding service properties for each device that supports the device service. 
   
     
     
         2 . The computer device of  claim 1 , wherein the operating system is further operable to identify at least one device endpoint that supports the device service by receiving an identification of a device endpoint that corresponds to a system-wide service object. 
     
     
         3 . The computer device of  claim 2 , wherein the system-wide service object defines how to use to the device services on the at least one device endpoint. 
     
     
         4 . The computer device of  claim 2 , wherein the system-wide service object identifies protocol-specific service properties of the at least one device endpoint for the device service. 
     
     
         5 . The computer device of  claim 1 , wherein the operating system is further operable to apply a filter to define a scope of the query. 
     
     
         6 . The computer device of  claim 1 , wherein the operating system is further operable to apply a filter to identify the one or more protocol specific adapter components. 
     
     
         7 . The computer device of  claim 1 , wherein the operating system is further operable to:
 monitor changes associated with connected or discoverable devices having the devices service; and   update the list of device endpoints that support the device service based on the monitoring.   
     
     
         8 . The computer device of  claim 7 , wherein the changes associated with connected or discoverable devices include one or more of an addition of a device endpoint having the device service, a deletion of a device endpoint having the device service, and a modification in a device endpoint having the device service. 
     
     
         9 . A method for service discovery on a computer device, comprising:
 receiving, at an operating system executing on the computer device, a query from an application executing on the computer device for a device service including one or more protocol-specific services connected to or discoverable by the computer device;   mapping, by the operating system, the query to one or more protocol-specific adapters selected based on the protocol-specific services;   identifying, by the operating system, at least one device endpoint representing at least one device that supports the device service; and   generating, by the operating system, a list of device endpoints and corresponding service properties for each device that supports the device service.   
     
     
         10 . The method of  claim 9 , wherein identifying the at least one device endpoint further comprises receiving an identification of a device endpoint that corresponds to a system-wide service object. 
     
     
         11 . The method of  claim 10 , wherein the system-wide service object defines how to use to the device services on the at least one device endpoint. 
     
     
         12 . The method of  claim 10 , wherein the system-wide service object identifies protocol-specific service properties of the at least one device endpoint for the device service. 
     
     
         13 . The method of  claim 9 , further comprising applying a filter to define a scope of the query. 
     
     
         14 . The method of  claim 9 , further comprising applying a filter to identify the one or more protocol specific adapter components. 
     
     
         15 . The method of  claim 9 , further comprising:
 monitoring changes associated with connected or discoverable devices having the devices service; and   updating the list of device endpoints that support the device service based on the monitoring.   
     
     
         16 . The method of  claim 15 , wherein the changes associated with connected or discoverable devices include one or more of an addition of a device endpoint having the device service, a deletion of a device endpoint having the device service, and a modification in a device endpoint having the device service. 
     
     
         17 . A computer-readable medium storing instructions executable by a computer device, comprising:
 at least one instruction for causing the computer device to receive a query for a device service including one or more protocol-specific services connected to or discoverable by the computer device;   at least one instruction for causing the computer device to map the query to one or more protocol-specific adapters selected based on the protocol-specific services;   at least one instruction for causing the computer device to identify at least one device endpoint representing at least one device that supports the device service; and   at least one instruction for causing the computer device to generate a list of device endpoints and corresponding service properties for each device that supports the device service.
