Youtube Playlist App

The application saves locally the metadata of the videos which are in one or more of the playlists created by the authenticated user. For each video the data stored are the title, id, views, number of likes and number of dislikes and name of file is suffixed by the current date.

Use cases

• Videos are on Youtube are often removed without notice and their metadata are lost. With this application it is easy to find them from local storage by searching their video id.

• If playlists are polled regularly and enough data are gathered, one can generate more advanced statistics on them

• The current application can be modified/extended to store more metadata possibly in a better storage format that allows queries and faster access.
