The first alpha version of Skosmos 3 has been published! This release provides a peek into the upcoming next major version of the Skosmos publishing tool for SKOS controlled vocabularies.

The release features a reimplemented front-end with a fresh layout and improved accessibility, as well as many architectural improvements and modernization of the codebase.

Who's working the most higher-order #classification systems of things in the world? Systematics in biology work on classifying all living things. Every field has their own classification systems. Is there a field that integrates those classification systems to create a "taxonomy of everything"? When I search for that concept I'm pointed towards people working on #SemanticWeb - I'm curious if there are any good sources out there to read up on, especially actual attempts/examples! #taxonomy

Is there a data structure that can sensibly handle multiple hierarchical classification systems?

e.g. an Orange, in terms of phylogeny is
Plantae->Eudicot->...->Citrus->sinensis

and in terms of usefulness, is
Thing->Food->fruit->orange
(and it could have multiple parents in this taxonomy, e.g. cleaning product)

Bonus points for cool visualisations of this kind information.

#decompwlj ➡️ It's a decomposition of positive integers. The weight is the smallest such that in the Euclidean division of a number by its weight, the remainder is the jump (first difference, gap). The quotient will be the level. So to decompose a(n), we need a(n+1) with a(n+1)>a(n) (strictly increasing sequence), the decomposition is possible if a(n+1)<3/2×a(n) and we have the unique decomposition a(n) = weight × level + jump.

We see the fundamental theorem of arithmetic and the sieve of Eratosthenes in the decomposition into weight × level + jump of natural numbers. For natural numbers, the weight is the smallest prime factor of (n-1) and the level is the largest proper divisor of (n-1). Natural numbers classified by level are the (primes + 1) and natural numbers classified by weight are the (composites +1).

For prime numbers, this decomposition led to a new classification of primes. Primes classified by weight follow Legendre conjecture and i conjecture that primes classified by level rarefy. I think this conjecture is very important for the distribution of primes.

It's easy to see and prove that lesser of twin primes (>3) have a weight of 3. So the twin primes conjecture can be rewritten: there are infinitely many primes that have a weight of 3.

I am not mathematician so i decompose sequences to promote my vision of numbers. By doing these decompositions, i apply a kind of sieve on each sequences.
