Abstract: The present invention is directed to facilitating communications and interoperability between/among applications and services. Such applications and services may be running on or associated with disparate platforms. The apparatus of the present invention provides for a message set that can be used by services to advertise available services, and by applications to identify desired services. According to certain embodiments, applications may subscribe to available services, such as display services. In a further aspect of some embodiments, applications executable on and services available from disparate platforms are not required by themselves to support communications between/among the platforms. Instead, such support may be obtained from facilities that are provided as part of the platform itself.
