The existing program runs as follows.
1. A user inputs time range.
2. The program downloads all json in that time range from http://ftp.musicbrainz.org/pub/musicbrainz/data/changed-mbids/
(This is a list of MBID(=musicbrainz id) of artists, recordings, releases that have been updated during that time range.)
3. Converts the MBID to artist names
4. Exports to csv or xlsx
It has some problems.
1. A user can input date range, but can't input time range.
2. I want to allow the user to input which "type" of MBID to consider. I will explain this in more detail once you post message.
I will tell you more details and send the program once you post a message.
