Supporting multiple service discovery protocols on a device

A method for receiving a request for metadata of one or more services provided by a multi-functional peripheral (MFP), wherein the MFP comprises a plurality of service applications that each provides at least one service, wherein the MFP supports a plurality of service discovery protocols (SDPs), the method comprising:

• receiving the request from a client, wherein:
• each SDP service module of a plurality of SDP service modules implements a different SDP of the plurality of SDPs;
• each SDP service module of the plurality of SDP service modules interfaces with a different SDP adapter module of a plurality of SDP adapter modules;
• each SDP adapter module of the plurality of SDP adapter modules interfaces with a device service management system (DSMS) that obtains metadata for each service of the plurality of services;
• one of the plurality of service applications includes a print process for processing print data and causing a printed version of an electronic document reflected in the print data to be generated;
• based on the request, a particular SDP service module of the plurality of SDP service modules sending a second request to the corresponding SDP adapter module;
• based on the second request, the corresponding SDP adapter module sending a third request to the DSMS;
• the DSMS sending the metadata to the corresponding SDP adapter module;
• the corresponding SDP adapter module sending the metadata to the particular SDP service module;
• and
• based on the metadata, generating and sending a response to the client.

A machine-readable medium for receiving a request for metadata of one or more services provided by a multi-functional peripheral (MFP), wherein the MFP comprises a plurality of service applications that each provides at least one service, wherein the MFP supports a plurality of service discovery protocols (SDPs), the machine-readable medium carrying instructions which, when processed by one or more processors, causes:

• receiving the request from a client, wherein:
• each SDP service module of a plurality of SDP service modules implements a different SDP of the plurality of SDPs;
• each SDP service module of the plurality of SDP service modules interfaces with a different SDP adapter module of a plurality of SDP adapter modules;
• each SDP adapter module of the plurality of SDP adapter modules interfaces with a device service management system (DSMS) that obtains metadata for each service of the plurality of services;
• one of the plurality of service applications includes a print process for processing print data and causing a printed version of an electronic document reflected in the print data to be generated;
• based on the request, a particular SDP service module of the plurality of SDP service modules sending a second request to the corresponding SDP adapter module;
• based on the second request, the corresponding SDP adapter module sending a third request to the DSMS;
• the DSMS sending the metadata to the corresponding SDP adapter module;
• the corresponding SDP adapter module sending the metadata to the particular SDP service module;
• and
• based on the metadata, generating and sending a response to the client.
