Update existing scraped data

Hi,

I’d like to update (refresh) data for my films (300+) and TV Series (50+) database. I do not want to add new posters or fanart, only update some information that can be updated time from time. For movies it may be ratings or information about movie collection (for TheMovieDB), for TV series – ratings, episodes plot and so on. Also I think that default episode poster may be added.

I know that tvdb.com API has a field like “lastupdatemoment”, so it is possible to compare it and update if needed. TheMovieDB API doesn’t seems to have such a field, however it is possible to just update all information about films. I think that all scraped IDs are saved in the database so it is very easy to update based on existing IDs so search process is not needed.

What do you think?
