Add exemplar tags

[neuromechanist]

I have added a couple of tags with references in the Annotation column. I think there are some outstanding points:

1. Should the database names also defined in the prefixes (I assume not, because the names are already available in OBO)
2. Should we use has_dbxref or db_xref for cross-referencing (or any other label)? has_dbxref is defined here and db_xref is defined here.
3. What should I do for the abbreviations, like LHJ and RHJ? Many of them are quite well-known and handy to use

Thanks Kay,

I corrected the Annotations and added obo to the prefix table.

There are some circular or incorrect references and other syntax errors:

• Head-landmark lists its parent as Anatomical-landmarks. It should be Anatomical-landmark
• Torso-chest-landmark also lists Anatomical-landmarks as it parent.

• HED tag names cannot have blanks or parentheses. By convention only first letter is capitalized.

  • Left-helix-tragus-junction
  • Right-helix-tragus-junction
  • Vertebra-promines

The stuff in parentheses should probably go in the description.

Addressed!
