"Common Cell Type Nomenclature for the Mammalian Brain" by Miller, et al. was published at the very end of 2020, in eLife. This article captures what is also described on the Allen Brain Map portal, with more information and use cases, and links to Github, refs, etc. The CCN was created to help researchers standardize cell type naming, and associate primary data with key metadata and taxonomies to facilitate analysis. The nomenclature convention can be used for any cell type, not just brain (or mammals!). Check it out, and let us know what you think! Improvements? New use cases? Other publications?
