+### Gist of a JSON Database
+Example of how CAMHD metadata might be organized in a json database.
+
+1 file that describes all video files in the archive  
+1 file per video that describes all frames in that video  
+1 file per video that describes every annotated frame in that video.  
+
+See examples in the repo and listed below.
+
+#### archive_file_meta.json
+Contains a list of all video files on the archive and general metadata about each file.
+
+#### CAMHDA301-20160101T000000Z_frame_meta.json
+File level list of all frames within a single video file, along with metadata for each frame.
+
+#### CAMHDA301-20160101T000000Z_annotations.json
+File level list of all frames within a single video file, along with their annotations.
