We had discussions over this ordinals in the past, IIRC. I happen to own an English version of the paper and I can understand it was rejected, I would do the same. (The last section is titled "A giant step for mankind".)
The confusion which floods this programming forum the last couple of days is also a good indicator. Let's all do something else. R.E.

But it doesn’t work well with the concept of having only an existential (1–9) and universal (0) qualifier. So sadly, we have to get around that limitation some way or th’other, I think. • edges I totally forgot about this when dealing with lines of the example which never contained 0s (other than implicitely trailing ones) because I think data should always look like that (regex): [1-9]+ with implicit trailing 0* So that’s another question @Bo: do we need to have things like 32051 in any place other than in a query? it used to describe a concept, but I think that was merely an aid for people thinking in terms of variables and relational db otoh, the example explicitely praised the benefits of being able to see which concepts are met by a query so maybe we have to deal with this I just had some ideas and they all don’t get it done correctly. I need to take some rest first, but the representations we have been constructing are obviously insufficient.
