 Record ids:
 * 1:    a part, type identified by either "LIBREFERENCE" or "DESIGNITEMID"
-* 2:    a pin on a part
+* 2:    a pin on a part, with types indicated by "ELECTRICAL"
+    * 4:            "Passive"
+    * 7:            "Power"
+* 4:    a "Annotation", which appears to just be a text box for referential purposes
 * 6:    a "drawing" I think... "Xn"/"Yn" are values of where a line should be drawn
+* 17:   a "Power Port", used commonly as GND or VCC, identified by "TEXT", "LOCATION.X", "LOCATION.Y",
+and a symbol denoted by "STYLE"
+* 25:   a "Net Label", which is similar to a "Power Port" in giving net designation to a wire,
+but doesn't come with a symbol (aka STYLE)
+* 27:   a "Wire", aka connecting line used to determine net associations
 * 34:   a designator?
-* 41:   text associated with a part - lots of different types indicated by "NAME"
+* 41:   text associated with an "OWNERPARTID" - lots of different types indicated by "NAME"
     * PinUniqueId:  I suspect a unique id for the associated pin
     * Fitted:       ...wat?
     * Comment:      self explanatory
 * 44:   a container of "models" aka record 45's - see below
 * 45:   appears to be a reference to which "model" a particular part can be represented by. Since this is just a
 possible model, the one actually selected for a given part will have the "ISCURRENT" flag set to "T"

+## Net Association
+Altium seems to have a very very very bizarre way of designating or determining the designation of what is a net,
+and what's connected to that net.
