======================================================

Each event can be assigned one or more Hierarchical Event Descriptor (HED) Tag (see [https://github.com/BigEEGConsortium/HED/wiki/HED-Schema](https://github.com/BigEEGConsortium/HED-schema/wiki/HED-Schema) for more details) under the optional `HED` column.
HED is a controlled vocabulary of terms describing events in a behavioural paradigm. It was originally developed with EEG in mind, but is applicable to all behavioural experiments. Each level of the hierarchical tags are delimited with a forward slash ("/"). Multiple tags are delimited with a comma. Parentheses (brackets) group tags and enable specification of multiple items and their attributes in a single HED string (see section 2.4 in HED Tagging Strategy Guide - [http://www.hedtags.org/downloads/HED%20Tagging%20Strategy%20Guide.pdf](http://www.hedtags.org/downloads/HED%20Tagging%20Strategy%20Guide.pdf)). For more information about HED and tools available to validate and match HED strings, please visit [www.hedtags.org](http://www.hedtags.org).
