32184.dat     Technic Axle Joiner Perpendicular  3L
32068.dat     Technic Axle Joiner Perpendicular 3 Long
32291.dat     Technic Axle Joiner Perpendicular Double
41678.dat     Technic Axle Joiner Perpendicular Double Split
42003.dat     Technic Axle Joiner Perpendicular with 2 Holes
32557.dat     Technic Pin Joiner Dual Perpendicular

I'd like to seek the opinion of the community. I am seeking ideas and
suggestions, but not hoping for concensus, so I will make the final decision
based on what I read here.

Doing nothing is not an option as we need to discriminate between 32184 and
32068, which have essentially the same description.

Technica (http://isodomos.com/technica/registry/connect/conn_7.php) calls these
all "Cross Blocks", but is still imperfect in that it fails to describe that
32557 is a Pin to Pin connector.

Peeron follows LDraw.

Bricklink uses:
6536    Technic, Axle and Pin Connector Perpendicular
32184   Technic, Axle and Pin Connector Perpendicular 3L with Center Hole
32068   Technic, Axle and Pin Connector Perpendicular 3 Long
32291   Technic, Axle and Pin Connector Perpendicular Double
41678   Technic, Axle and Pin Connector Perpendicular Double Split
42003   Technic, Axle and Pin Connector Perpendicular with 2 Holes
32557   Technic, Pin Connector Perpendicular Long

As an opening bid, I'm suggesting adding dimensions and the sequence of axle
holes / pin holes:
6536.dat      Technic Axle Joiner Perpendicular 1 x 2 (Axle/Pin)
32184.dat     Technic Axle Joiner Perpendicular 1 x 3 (Axle/Pin/Axle)
32068.dat     Technic Axle Joiner Perpendicular 1 x 3 (Axle/Pin)
32291.dat     Technic Axle Joiner Perpendicular 2 x 2 (Axle/Twin Pin)
41678.dat     Technic Axle Joiner Perpendicular 2 x 2 Split (Axle/Twin Pin)
42003.dat     Technic Axle Joiner Perpendicular 1 x 3 (Axle/Pin/Pin)
32557.dat     Technic Pin Joiner Perpendicular 2 x 3 (Pin/Pin/Twin Pin)

Comments please.

Thank you for all the comments on this (including those that veered off-topic).
I like the "Cross Block" designation, especially as this is a common theme in
the LEGO descriptions. It has the added benefit that it is shorter than "Joiner
Perpendicular", leaving more space for qualification if needed. So I will go
ahead with:

6536.dat      Technic Cross Block 1 x 2 (Axle/Pin)
32184.dat     Technic Cross Block 1 x 3 (Axle/Pin/Axle)
32068.dat     Technic Cross Block 1 x 3 (Axle/None/Pin)
32291.dat     Technic Cross Block 2 x 2 (Axle/Twin Pin)
41678.dat     Technic Cross Block 2 x 2 Split (Axle/Twin Pin)
42003.dat     Technic Cross Block 1 x 3 (Axle/Pin/Pin)
32557.dat     Technic Cross Block 2 x 3 (Pin/Pin/Twin Pin)

44489.dat     Technic Cross Block 2 x 2 Bent 90 (Pin/Pin/Pin)
63869.dat     Technic Cross Block 3 x 2 (Axle/Triple Pin)
