Hi Evan,
To answer your question with a quote from a google search on the subject:
<quote>
Purpose:
The IPC-D-356 format was designed to define a standard netlist format by
which bare
board test information can be represented. In the simplest of forms,
this means it must be
able to store netlist information along with XY coordinates, and even
reference
designators and pin numbers (if they exist). I feel like ending this
article here before it
gets unmanageable, but then Pete Waddell wouldn’t be happy, so let’s
proceed. If all the
information that a test system would need to know to verify and test a
bare board could
be represented in a single file, it would bring consistency to the
testing world. IPC-D-
356 does just that.
Does it work?
Yes. You will find that virtually all the test equipment manufacturers
either support the
IPC-D-356 format now, or are in the process of supporting it. Are there
problems with
it? Of course. Certain special pad types are not supported and additions
could be made
which would assist computer aided repair stations, but all in all it’s
pretty good.

Found with the following link:

The IPC organisation gives:

for a short introduction and index to the description of the complete
standard.
Kind regards,
Bert Timmerman.
