# ERC721EditionsDFS The ERC721EditionsDFS contract is used for projects where the metadata for each token is the same, but it has an added set of functionality around the concept of “editions.” An edition is defined in the IEditionCollection interface, and lets you set a name, token supply, and initial token ID for a distinct grouping of tokens on the same contract. In the Highlight interface these will show up as distinct collections, and you can set the metadata for each edition separately. You can add new editions continuously over time, allowing you to reuse the same contract again and again. Each edition will have distinct metadata, but each token within an edition will have the same metadata. Note that on 3rd party platforms these will appear as grouped together into the same collection. ### Contract link {% embed url="" %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
