Response: Theme-based categories are somewhat problematic, especially
when there is System overlap (Friends, Belville, Scala, etc.). I think here
the category definition should be modified. Agree on moving balls to the Ball
category. This is a relatively new category (October, 2018) and that was always
the intent.

Could part
 
Part No: x12  Name: Brick, Round 1 x 1 with Ball (Finial)
* 
x12 Brick, Round 1 x 1 with Ball (Finial)
Parts: Brick, Round
be a modified plate round with ball?

I find that hard to believe it’s a plate.

Good point, while I like "Technic" as a whole roughly the way it is, I feel like
some renovations are in order. "Link" is a tiny subcategory that is rarely used,
while the main Technic vanilla category (a leftover bin) contains more than 10
times the number of parts and is used all the time. I think it would be good
to redistribute some parts within Technic (or, in the case of SylvainLS'
suggestion, out of Technic.. but generally mostly within Technic), so that the
subcategories are more comparable in relevance.

Agreed.

So,
 
Part No: 2852  Name: Technic Engine Connecting Rod
* 
2852 Technic Engine Connecting Rod
Parts: Technic
isn’t that a Technic Link?

 
Part No: 4185  Name: Technic Wedge Belt Wheel (Pulley)
* 
4185 Technic Wedge Belt Wheel (Pulley)
Parts: Wheel
a wheel, and
 
Part No: 2815  Name: Tire Technic Wedge Belt Wheel
* 
2815 Tire Technic Wedge Belt Wheel
Parts: Wheel, Tire & Tread
a tire?

 
Part No: 2743  Name: Technic Slope 4 x 1 x 1 2/3
* 
2743 Technic Slope 4 x 1 x 1 2/3
Parts: Technic
 
Part No: 2744  Name: Technic Slope 6 x 1 x 1 2/3
* 
2744 Technic Slope 6 x 1 x 1 2/3
Parts: Technic
 
Part No: 2823  Name: Technic Forklift Fork
* 
2823 Technic Forklift Fork
Parts: Technic
modified Technic Bricks?

 
Part No: 32072  Name: Technic Knob Cog / Gear / Wheel with Axle Hole (+ Orientation)
* 
32072 Technic Knob Cog / Gear / Wheel with Axle Hole (+ Orientation)
Parts: Technic
would be a Technic, Gear if the part about teeth wasn’t in the definition.

We could also put all the digger buckets together (even those in Vehicle).
(That could lead to wondering about the tipper buckets and ends but it seems
to me digger buckets have a recognizable shape the tipper buckets don’t have,
especially the tipper ends.)

I would also argue that
 
Part No: 32474  Name: Technic Ball Joint
* 
32474 Technic Ball Joint
Parts: Technic
 
Part No: 53585  Name: Technic Ball Joint with Through Axle Hole
* 
53585 Technic Ball Joint with Through Axle Hole
Parts: Technic
are Ball Joints and we could have a category for Ball Joints but those are divided
in the theme categories Bionicle and Hero Factory and as much as I don’t like
function categories, especially when shape is more obvious / directly recognized,
I really don’t like theme categories at all.


  I've been thinking about a category "Technic, Transmission" for this family
of parts, to add a bit of structure by taking parts out of the vanilla category...

Not agreed.  First, “Transmission” is a function.  Then, I don’t think it’s easy
to know which parts can function in a Transmission or as Transmitters.
If we are taking Transmission as in Car Gearbox, why aren’t gears in there, or
differentials?

Super.

In the same vein,

mixes 6 (+2 variants) link-bars and 4 treads / chain-links with 2 attachments.

I fear the only link (pun intended) between these two groups is that they use
the word “link,” and not all of them do at that!

I think it would make more sense to either
a. put the treads (and attachments) in Tire & Tread, where other treads already
are (though one-piece treads),
b. make a new “Tread” category with all the treads and their attachments (and
rename Tire & Tread to Tire).

I’d be partial to (a).

Forgot to add:  How should someone know a tread is “Technic” or not?  How
should someone know the difference between a “Chain Link” and a “Tread”?


  Then, that would leave the Technic, Link category with only 6(8) parts….

I wasn’t implying you were the culprit

But I think that’s what you’d get if you let soak ABS in bleach, or in very strong
peroxyde, for too long.
The plastic is over-degraded.
The colour-marbling is a cue.

It seems so.

On a note, is it really “children playing”?

In France, it’s “attention, école” (beware, school) when the kids have schoolbags
and “attention, endroit fréquenté par des enfants” (beware, area frequented by
children) when they don’t.
I mean, they don’t always play, especially going to school

It was just a warning for what it's worth, that's all. I'm just talking
about balance. If that is superfluous and you already had a balanced approach
in mind, then just ignore my point. And if I am the only one here who suffers
from that perfectionist urge once I think about things too deeply, well, then
I'm glad

I think you’ve made that point times enough.

Take my example: I, for one, have refrained several times in this thread from
saying this project is taking the whole problem (yes, yes, I know, there’s no
problem ) by the wrong end, that we should have found and defined attributes
first to… er… oops?

Jean tried to avoid circular definitions.
Removing a few words, yours becomes: “Cones: conical items and truncated cones.”

Othewise we could also have: “Cones: well, cones, you dummy!”

The definition of Brick depends on the term brick.

Brick - For basic and unmodified LEGO system building bricks with one
or more top studs, plain straight sides and a hollow bottom.

Plus it relies on the terms basic and unmodified without defining them. Of course,
if you understand the context, then you know what the meaning is. But unmodified
could mean as supplied by LEGO, as it does elsewhere on BL.

I didn’t say the other definitions were perfect

I think that is exactly the point. Where there is a simple unambiguous definition,
why not use it?

Because the more you explain, the fewer ambiguities there are?


  It would be possible to insert a formally correct mathematical
definition of a cone but does it really help any more than saying a cone is a
cone.

Well, there are several.  What do you think of “a degenerated hyperboloid of
revolution”


  
 
Part No: 35563  Name: Tower Roof 2 x 4 x 4 Half Cone Shaped with Roof Tiles
* 
35563 Tower Roof 2 x 4 x 4 Half Cone Shaped with Roof Tiles
Parts: Roof

Frankly, if this part has “Cone” in its description and isn’t in the Cone category,
then I think it’s not placed where it should.

Besides, the Roof category is useless because it’s too small, and parts in there
aren’t even “roofs”: most are cones, there’s one pyramid (which’s a cone with
a square base ), a big slope “assembly,” and crenels.
At most, the conical roofs could be in “Cone, Modified” if there were more of
them.


  Incidentally, this part uses the base word cone to define its shape. So presumably
people need to understand the word cone here, so why not in the definitions.

Many parts have their category in their name.  So, problem solved, no need to
define anything because the words are already used elsewhere?
