Database abstract
A single language for commercial timber
The database systematizes and standardizes information about timber species that matter in global trade. It establishes a unified description and coding system based on physical and mechanical properties, so a species can be searched, compared, classified and verified consistently rather than identified informally.
Six areas of application
From international trade to a workshop01
Global and regional timber trade
02
Wood-processing industry
03
EUDR and CITES circulation control
04
Export/import customs procedures
05
Research and education
06
Independent woodworkers and workshops
Functional capabilities
The system standardizes records by physical and mechanical parameters; supports search and filtering; compares and classifies entries; decodes unique species codes; and provides controlled data management.
Data: does not contain personal data
Architecture: any server infrastructure
OS: Linux Ubuntu LTS 24.04

25 cells of commercial timber taxonomy
5 × 5 · physical and mechanical properties
Each cell combines species with a defined hardness and durability profile. A cell can contain from 1 to 25 timber species; the matrix is the basis for a unified code and reproducible verification.

01 / CHALLENGE
Challenge
World commercial timber (WCT) lacks a unified scientific classification: species get confused, standards are fragmented, and origin/species verification is hard.
02 / HOW I BUILT IT
How I built it
I built a matrix system of WCT standards and a scientific taxonomy: each timber species is described by a feature matrix and classified/verified with Data Science — reproducibly and at scale.

◢ HOW IT HELPS YOU
How it helps you
Picture a shipment of premium timber: one trade name can hide different species, and telling them apart by eye is nearly impossible — hence mis-grading, disputes with suppliers and direct losses. UMZAR provides a unified scientific taxonomy and matrix verification: a species is identified by a set of features reproducibly and verifiably, not «on trust».
A unified scientific taxonomy — the end of species confusion and fragmented timber standards.
Matrix species verification — protection against species substitution and mis-grading.
Reproducible and scalable — a basis for industry standardization and expertise.
