"Marginalia are scribbles, comments and illuminations in the margins of a book." Wikipedia
Media Marginalia is a Wordpress Plugin that takes the concept of textual marginalia and applies it to video and audio.
It provides an interface to create/read/update/delete multi-media (text/video/audio) annotations for a given media file (video/audio).
Download the ZIP into the wp-content/plugins directory.
In the directory of your theme (e.g. twentyfourteen) within the wordpress themes directory, type the following commands to symlink to the custom SHOTS category templates:
ln -s ../../plugins/media-marginalia/category-shots.php category-shots.php
ln -s ../../plugins/media-marginalia/content-shot.php content-shot.php
Every specific shot category (e.g. 0001, 0002, etc.) must have its parent set to a SHOTS (slug=shots) category to tell it to use the above symlinked templates.
