WHAT IS MEP?

CURRENT MODEL

• User clicks MediaThread bookmarklet on Library of Congress video

• MediaThread bookmarklet scrapes metadata from Library of Congress and stores it in MediaThread’s local database

SIDELOADED METADATA

• MediaThread sends a second request to MEP for any metadata about the video, then adds the result to its database

• The user never knows MEP was queried

ADDED METADATA

• User adds annotations, commentary, tags, etc. to the video in MediaThread

• When the user publishes their work, MediaThread sends the user’s new metadata to MEP

ADDED METADATA

• The user’s metadata is added to what MEP knows about the video and what it sends to MediaThread next time that video is loaded

• If the Library of Congress can accept the new metadata, MEP will send it back to enhance the original source’s records

COMMENTARY

Commentary A woman can be seen rolling out a pie crust in the center of a table on a set of a kitchen. A pie is cooling on the sideboard. As the woman continues her work, the door opens and a big man dressed as a tattered tramp enters and gestures a request for food. The woman replies by hitting him with a rolling pin, knocking him to the floor.
