2. Working documents

Mapping of HED terms and their descriptions to known ontologies is:

Two other working documents hold portions of the HED-3G specification that are under development and will not be finalized for Release 1:

3. Schema viewers

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. For this reason, we provide links to three versions of the schema. The expandable HTML viewer is easier to navigate. Annotators can also use CTAGGER, which includes a schema viewer and tagging hints.
