Galaxy CoDex for finding tools, workflows, and training

International audience ; Galaxy offers an ecosystem containing thousands of tools, hundreds of tutorials, and a currently unknown number of workflows. The abundance of locations where these resources can be found, coupled with their diverse and fragmented nature, makes it incredibly difficult for Galaxy users to find and reuse tools, or to filter for all resources available for a specific research community, domain, or research area. By extension, it is also difficult for Special Interest Groups (SIG) to give visibility to their collective works.To improve the findability of tools, a pipeline (Galaxy Tool Metadata Extractor) was developed at the BioHackathon Europe 2023 to collect Galaxy suites from different locations, automatically extract their metadata (including bio.tools identifier and EDAM ontology concepts), and display this information as an interactive list that can be filtered to display tools that are relevant to a specific research community or domain (DOI:10.37044/osf.io/qjbxc). In developing this pipeline, two challenges were apparent: 1) many tools are missing proper bio.tools or EDAM annotations, and 2) a Galaxy SIG offers more resources than just tools. In fact, SIGs also offer training materials and workflows, which are often dispersed and poorly annotated. During the BioHackathon Europe 2023, and in a second community-hosted online hackathon in 2024, the microGalaxy SIG tackled the first challenge by working on tool annotation, thereby improving the EDAM annotations for more than 200 tools, and annotating more than 30 tutorials with EDAM concepts. Additional communities, including single-cell and imaging SIGs, have also started similar annotation efforts.To address the second challenge, and aggregate the sum of resources available to a SIG, the Galaxy Tool Metadata Extractor is now being extended to create the Galaxy Communities Dock or Galaxy CoDex. Galaxy CoDex includes a centralised webpage template and files that will enable domain communities to rapidly aggregate, curate, integrate, ...
