...especially what is necessary to represent at this level and what information
is implicit; notably there will be an implicit default wiring, but we allow
for case-by-case deviations
To escape a possible deadlock in analysis, I resort to developing
some kind of free-wheeling presupposition how the **Builder** could
be implemented — a centrepiece of the Lumiera architecture envisioned
thus far — which ''unfortunately'' can only be planned and developed
in a more solid way ''after'' the current »Vertical Slice« is completed.
Thus I find myself in the uncomfortable situation of having to work towards
a core piece, which can not yet be built, since it relies heavily on
the very structures to be built...
...and this line of analysis brings us deep into the ''Buffer Provider''
concept developed in 2012 — which appears to be very well to the point
and stands the test of time.
Adding some ''variadic arguments'' at the right place surprisingly leads
to an ''extension point'' — which in turn directly taps into the
still quite uncharted territory interfacing to a **Domain Ontology**;
the latter is assumed to define how to deal with entities and relationships
defined by some media handling library like e.g. FFmpeg.
So what we're set to do here is actually ''ontology mapping....''
Facing quite some difficulties here, since there are (at least)
two abandoned past efforts towards building a render node network
in the code base; the structure and architecture decisions from these
previous attempts seem largely valid still, yet on a technical level,
the style of construction evolved considerably in the meantime. Moreover,
these old fragments of code, written during the early stages of the
project, were lacking clear goals and anchor points at places;
the situation is quite different now in this respect.
Sticking to well proven practice, the rework will be driven by a test setup,
and will progress over three steps with increasing levels of integration.
