This set of interfaces and contracts are all related to the ERC1155 Multi Token Standard.
The EIP consists of three interfaces which fulfill different roles, found here as {IERC1155}, {IERC1155MetadataURI} and {IERC1155Receiver}.
{ERC1155} implements the mandatory {IERC1155} interface, as well as the optional extension {IERC1155MetadataURI}, by relying on the substitution mechanism to use the same URI for all token types, dramatically reducing gas costs.
Additionally there are multiple custom extensions, including:
-
designation of addresses that can pause token transfers for all users ({ERC1155Pausable}).
-
destruction of own tokens ({ERC1155Burnable}).
Note

This core set of contracts is designed to be unopinionated, allowing developers to access the internal functions in ERC1155 (such as _mint ) and expose them as external functions in the way they prefer. On the other hand, ERC1155 Presets (such as {ERC1155PresetMinterPauser}) are designed using opinionated patterns to provide developers with ready to use, deployable contracts.

These contracts are preconfigured combinations of the above features. They can be used through inheritance or as models to copy and paste their source code.
