Codes that match in every language

Every unit in Math has a code, such as topic-a for Topic A. A code names a unit the same way in every language, so a report or another tool can find Topic A and Tema A as one unit.

Most fields belong to one language's version, as a title does. The code is different: Math marks it as shared by every language. Change a unit's code in Spanish, and the same save changes it in English; add a Spanish version, and it takes the code English has. Give it a different one, and the tools refuse.

Try it: compare the two code columns; then read what Lucía would be told on adding Lesson 5 in Spanish with a code of its own.

Codes of Math's units, as editors see them

Unit	Code in English	In Spanish	Code in Spanish
Level 2	level-2	Nivel 2	level-2
Module 1	module-1	Módulo 1	module-1
Topic A	topic-a	Tema A	topic-a
Lesson 1	lesson-1	Lección 1	lesson-1
Lesson 2	lesson-2	No Spanish version
Topic B	topic-b	Tema B	topic-b
Lesson 3	lesson-3	Lección 3	lesson-3
Lesson 4	lesson-4	Lección 4	lesson-4
Module 2	module-2	No Spanish version
Topic C	topic-c	No Spanish version
Lesson 5	lesson-5	No Spanish version

11 units. The 7 with a Spanish version have the same code in Spanish as in English. Lesson 2, Module 2, Topic C, and Lesson 5 have no Spanish version, so they have no Spanish code.

Adding Lesson 5 of Math in Spanish, with the code leccion-5

Lección 5 can't be added with the code leccion-5

Lesson 5's code is lesson-5, and a unit has the same code in every language. Add Lección 5 without a code, and it takes lesson-5.

If you tried this

So a unit's code is the one value you can count on to match across languages. Had Lucía changed Tema A's code, Topic A's would have changed in the same save, and Topic A's history would show a saved version of its own, by Lucía, at the same moment, made by her change to Tema A. Your tools can say so as you save: “Also changed: English.”
