I was looking at the (unfinished) example sampler
plugin here:

I ran through the mental exercise of trying to figure out how to
finish it, and I have a question about the UI extension. How does a
UI tell its plugin to load a sample file? The example has a TODO in
its run function that indicates it will react to an LV2_Event that
contains a pathname for a file. I don't understand how a UI will
create this event.
First, this discussion belongs on the LV2 mailing list. :-) In fact,
we've been discussing it recently. See [1]
Second, the current intention is to send an Event with a URL to load a
sample file (whether the event comes from a UI or another plugin or
whatever). In order to accomplish this, a standard event type has to be
created. That's what the "Atom extension"[2] -- it's like a standard
library of event types.
HOWEVER, stepping back a little bit, in you could create your own
private event type and send it over an Event port.

[2] There's talk of renaming it the Atom extension to something
like "Variant" so that it's easier to understand.
