Movie Metadata Storage

Assuming I can query IMDB etc successfully and retrieve metadata for an avi. Is there an existing file format for that metadata to store beside the avi? I can create my own XML/JSON based mymovie2010.avi.metadata file, but I wonder if someone开发者_运维百科 has created an interchange.

I ended up using the raw JSON from http://www.imdbapi.com/ Since the request/response was easy enough to get. I store it next to the video in an imdb.txt. To be used for further processing later.
