Namespace Convention (***)

About

This convention aims to prevent conflict when deciding the name for your scoreboards, functions, storages, etc. by using a "namespace prefix".

Implementation

A namespace prefix must be used whenever it is possible. This includes tags (datapack), tags (/tag), nbts, scoreboards, functions, advancements, loot tables, structures, world generation settings, recipes, data storage.

There is no rule specifying how you should design your namespace prefix, but these are some of the examples:

scoreboard objectives add bb.var dummy

In this example bb is the namespace which is shortened from boomber due to 16 characters limitation. I like to keep the scoreboard namespace short and use . to seperate the namespace from the name.

tag @s add boomber.foo.bar

In this example, I use a full boomber prefix, because tags don't have a character limit.

data merge storage boomber:foo/bar {}

In this example data storage already has support for namespacing, so I don't need to use a prefix.

give @s diamond{boomber: {custom_data: 123}}

In this example, I wrap the custom_data nbt inside another tag, allowing it to act as a namespace.

The above examples are my style of namespacing, but there are many other approaches that you can take, such as namespace_foo, NAMESPACEfoo, namespace.foo, namespace:foo and namespace/foo. Your imagination is the limit!

Note

Using minecraft namespace to modify vanilla's behavior is a special case and it is allowed within a reasonable situation.
However, for example, setting "replace" to true in the tick.json function tag is not a "reasonable situation", because that would prevent other datapacks from working.
