• So tags in add_tags always have a spawn_weight > 0?

• Some modifiers don't have any tags with spawn_weight > 0 but do have add_tags.
  Like AttackSpeedCorrupted. They can spawn?

• It is not always clear on what item a modifier can spawn.
  A tag like "2h_mace_elder" is obvious but a tag like "has_caster_mod" isn't clear for me.
  Does the tag "dex_armour" apply only to dex_helmet,dex_boots,dex_gloves,dex_body_armour or also dex_int_gloves?

No, see e.g. "no_attack_mods", added by IntMasterItemGenerationCannotRollAttackAffixes.

Some modifiers don't have any tags with spawn_weight > 0 but do have add_tags. Like AttackSpeedCorrupted. They can spawn?

They can't spawn through normal means, but they can e.g. be crafted (DexMasterGlobalAttackSpeedCrafted1) and can then influence the spawning of further mods.

It is not always clear on what item a modifier can spawn.

There are three ways that I know of from which an item can get tags:

1. From the base item. E.g. "dex_armour" can only be on an item of a base with exactly that tag. See tags in base_items.json for that.
2. From the item being influenced. E.g. "2h_mace_elder" is the tag added to elder influenced 2h maces. See item_classes.json for the tags provided by influences on items of each item class.
3. From other mods that are already on the item. E.g. "has_caster_mod" is added by a bunch of mods. That's what adds_tags in mods.json is for.

I'm trying to link item classes to their possible modifiers, spawned/corrupted/enchanted/..
Now I understand I have to match the tags from base_item.json with the ones (weight>0) in mods.json.
Thanks.

But then some of the tags in base_items.json don't match any tags in mods.json.
Like "amuletatlas2".

Your example "IntMasterItemGenerationCannotRollAttackAffixes" doesn't have any spawn weights.
The added tag "no_attack_mods" tells me it cannot spawn on anything with Catarina's "Cannot roll Attack Mods".
So it can it be crafted on any other gear?
(Beside items that have already mods of the same group)

If a stats id has a range 0-0, like on EnchantmentOfBladesOnHit4, it can't exist?
If I'm right, can you add it to the documentation?

Tags might be used for different things by the game, too. Or that's just something GGG added and never used.

Your example "IntMasterItemGenerationCannotRollAttackAffixes" doesn't have any spawn weights.

It works the other way around. IntMasterItemGenerationCannotRollAttackAffixes is Catarina's "Cannot roll Attack Mods". If you craft it onto an item, that item gets the tag "no_attack_mods". That tag prevents a bunch of mods from spawning on items, as it's listed with a spawn_weight of 0 on them, see e.g. AccuracyRatingPerFrenzyChargeUber1.

Crafting mods onto gear ignores spawn_weights. For crafting options, see crafting_bench_options.json.

If a stats id has a range 0-0, like on EnchantmentOfBladesOnHit4, it can't exist?

No idea what the game does there. Stats with value 0 have no effect either way.
