ABSTRACT:
Storing metadata updates for a read-only media file. The media file has content and metadata describing the content. Responsive to a user or application program updating the metadata, the invention stores the updates to the metadata in an update data store when the media file is in the read-only state. The update data store is associated with the media file. The invention reconciles the metadata of the media file with the updates stored in the update data store to create updated metadata. The invention attempts to write the updated metadata to the media file when the media file is available with write access.
