Techniques for supporting multiple service discovery protocols (SDPs) on a network-enabled device (NED) are provided. The NED includes a plurality of SDP services, a plurality of SDP adapters, and a device service management system (DSMS). Each SDP service interfaces with one SDP adapter. Each SDP adapter interfaces with the DSMS. Each SDP adapter translates messages from its corresponding SDP service into a format the DSMS understands, and vice versa. The DSMS manages service metadata information about one or more services hosted (or provided) by the NED. In response to a request, from a client, for metadata of one or more services hosted by the NED, a SDP service requests the metadata from its corresponding SDP adapter. The SDP adapter requests the metadata from the DSMS, which responds to the SDP adapter with the metadata. The SDP adapter sends the metadata to the SDP service, which sends the metadata to the client.
