Google the term "Hierarchical Network Design".
Edge, Core, and Access layers are the typical terminology. Edge is
where you interconnect with other networks. Access is where you connect
users. Core is in the middle. Edge and Access layers have different
functionality focuses. Edge and Access both need to be gatekeepers to a
certain extent. Core just needs to move traffic quickly.
.....and yeah it's possible core and edge are the same box, and it's
possible all 3 are the same box. It's just a way of thinking about
design. When you expand and start needing more boxes to carry load it's
a useful way of segregating functions.

I keep hearing edge, edge to me means the far edge of the network, the
core, well is the core.
What do you call the edge of the network when you are calling your
core the edge?

Is there a reference somewhere that describes which options are
needed for what on the MX204? I've been eyeing one for the edge
for several months now, and it's getting to the point where we
probably need to pull the trigger sooner rather than later.
It looks like for a edge device I might only need the base
licensing, but it's hard to tell for sure.

I would suggest looking seriously at the MX204 platform. New
with licensing it’s under 20k (negotiate hard and you can get
it closer to 15k). Very powerful without the power, space,
and line card expense of the MX80. The only real drawback to
them is they are a single routing engine rather than dual.
Having said that I can’t recall any time that we have had a
routing engine fail on a MX series router. Used to happen
all the time on our Cisco 7500’s - but we are talking ancient
history there.
We run a pair of MX204’s now, though we used a single one for
a long time.

about their licensing (looking at used ones that I can get for
about $5k). I also do not know what other options are out there.
