> Subsystems may be installed by calling Subsystem.install(String) (and also
> the install(String, InputStream) method). The code treats the given location
> string as a URI string which can be opened to obtain installation artifacts,
> unless the URI has a scheme of "subsystem" in which case an alternative leg
> of code is executed to install a persisted subsystem.
> It would be useful to extend this mechanism to add a new scheme
> ("idirfinder") which is also treated in special way; in this case the URI is
> passed to a service which can return a corresponding IDirectory object that
> matches the given URI, which the install code can then use to install a
> subsystem using the contents of the IDirectory. To achieve this, a
> modification to the subsystem install code is required (though not extensive
> as IDirectory objects are already used internally during install), and an
> interface for the IDirectory finder service must be defined.
> Adding this functionality would allow installation of subsystems from a
> variety of sources, including expanded archive, loose config (installation
> artifacts distributed across disk as produced by IDEs), in-memory etc as the
> only requirement is then to provide an IDirectory front-end to the content.
> The alternative of gathering the content and producing an archive file is not
> desirable due to the overhead this entails, particularly when an IDE is being
> used for rapid development, and small changes are being made frequently.
