Managing multiple web services on a single device

A printing device comprising:

• a first Web service that is addressable by one or more clients that are separate from the printing device and that are configured to communicate with the printing device over a network;
• a second Web service that is addressable by the one or more clients that are separate from the printing device;
• service metadata that contains:
• first service metadata for the first Web service, and
• second service metadata for the second Web service;
• and
• a service manager configured to:
• register the first Web service on the printing device,
• register the second Web service on the printing device,
• receive and store on the printing device first status or event data associated with the first Web service,
• receive and store on the printing device second status or event data associated with the second Web service,
• provide, to a client, printing device metadata that indicates that the printing device is currently configured to use aggregated data collection, and
• in response to a request from the client for status or event data and determining that the printing device is currently configured to use aggregated data collection, provide, to the client, both at least a portion of the first status or event data associated with the first Web service and at least a portion of the second status or event data associated with the second Web service.

One or more non-transitory machine-readable media carrying instructions which, when executed by one or more processors, cause:

• registering a first Web service, on a printing device, with a service manager of the printing device, wherein registering the first Web service includes the service manager receiving first service metadata of the first Web service;
• wherein the first Web service is addressable by one or more clients that are separate from the printing device and that are configured to communicate with the printing device over a network;
• registering a second Web service, on the printing device, with the service manager of the printing device, wherein registering the second Web service includes the service manager receiving second service metadata of the second Web service;
• wherein the second Web service is addressable by the one or more clients that are separate from the printing device;
• maintaining, on the printing device, device metadata that indicates metadata for the printing device;
• generating, at the printing device, service relationship data based on the first service metadata and the second service metadata, wherein the service relationship data indicates a relationship between the first Web service and the second Web service;
• and
• in response to one or more criteria, associated with the first Web service, being satisfied:
• determining, by the service manager, based on one or more of the service relationship data or the device metadata, that a set of one or more actions are to be performed with respect to the second Web service, and
• causing, by the service manager, the set of one or more actions to be performed with respect to the second Web service.
