HED library schema expandable HTML browser allows users to browse the schema terms and descriptors. (A) HED-SCORE library schema top-level describing the main types of EEG graphoelements included in SCORE. (B) Top-level term ‘Artifact’ is expanded to show the lower-level nodes of ‘Biological-artifact’. For data annotations, short forms are typically used (e.g., ‘Chewing-artifact’), and each short form can easily be mapped to its long-form paths (‘Property/Data-property/Data-artifact/Biological-artifact/Chewing-artifact’). (C) The extended description for ‘Epileptiform-interictal-activity’ node shown when hovering over the term. The ‘suggestedTag’ section shows recommend additional terms that a user might want to include along with this tag.
