GlycoPOST: expanding glycomics data sharing to glycoproteomics through the updated MIRAGE guidelines

GlycoPOST (https://glycopost.glycosmos.org) is a public mass spectrometry (MS) data repository for submitting and sharing glycan-related raw MS data along with structured experimental metadata, in accordance with the Minimum Information Required for A Glycomics Experiment (MIRAGE) guidelines. As of 1 September 2026, GlycoPOST hosts 602 projects containing 7.6 TiB of data, of which 445 are publicly available. In this update, we implemented major updates to GlycoPOST, expanding its scope from glycomics to glycoproteomics by incorporating the recent revisions published on the MIRAGE MS guidelines, in addition to enabling users to filter "presets," which are units for metadata in GlycoPOST, by keywords and last update date. The newly introduced concept of "project type" enables each GlycoPOST submission, referred to as a "project," to be classified according to whether it contains glycomics or glycoproteomics data. This makes it easier to select reusable metadata profiles (presets) by displaying only categories relevant to the experimental field. Furthermore, with the introduction of a project type specifically designed for glycomics-assisted glycoproteomics experiments, it is now possible to register data and metadata from both glycomics and glycoproteomics within a single project. These updates will promote standardized data sharing and reanalysis across glycomics and glycoproteomics using GlycoPOST.
