HED schema viewer¶

The HED schema is usually developed in .mediawiki format and converted to XML for use by tools. However, researchers wishing to tag datasets will find both of these views hard to read. All versions of the standard schema and library schemas including the prerelease versions available via the expandable HTML viewer. The .mediawiki sources can be viewed on the **hed-schemas GitHub repository using GitHub’s default markdown viewer.
