Abstract

Remote Subscription Services, or RSS, provides a mechanism for a PenPoint operating system user to subscribe to applications that are available on a server machine. The user's application list on the mobile computer will be updated when a connection is made to the appropriate application server. From this list the user will have the ability to subscribe to applications. After the user subscribes to a particular application, the application software is automatically updated if a new version becomes available. The user simply connects to the server and RSS will detect if the subscribed application is backleveled and, if it is, will install the new version without the need for user intervention.

Remote Subscription Services

      Remote Subscription Services, or RSS, provides a mechanism for
a PenPoint operating system user to subscribe to applications that
are available on a server machine.  The user's application list on
the mobile computer will be updated when a connection is made to the
appropriate application server.  From this list the user will have
the ability to subscribe to applications.  After the user subscribes
to a particular application, the application software is
automatically updated if a new version becomes available.  The user
simply connects to the server and RSS will detect if the subscribed
application is backleveled and, if it is, will install the new
version without the need for user intervention.

      The RSS client consists of a Pen-Based Computer running the
PenPoint Operating System and the client version of the RSS
application.  The RSS server would contain the necessary structures
and data to allow the client to realize what applications are
currently available on the server and where these applications are
physically located.  When the user connects to the server volume
these files are read and the list of available applications that the
user currently has on the tablet is compared against the list of apps
currently residing on the server.  Any new application is then added
to the users list and any applications found on the users list that
are no longer available on the server are removed.  When this step
has completed the user now has a current list of available
applications.

      The fact that the user chooses to subscribe to particular
applications is maintained during this synchronization and unless a
new application has been added to the list the user does not need to
do anything further with the list.  If a new application has become
available the user would then have the ability to subscribe to this
application also.

      Once the list synchronization is completed the user can begin
the application synchronization.  RSS will look...
