Meta-data
Besides all the standard data attached to each and every file, we also provide a 'metadata' field. Any data-structure can be added to this field. This useful for attaching data to media which would otherwise not fit in any other fields.
How this data is entered is highly dependant on the method of media-intake. Check out the appropriate documentation for more information.
Special meta-data
There are a few specially reserved meta-data tags by the MediaFactory, their meaning is listed here:
exif
If a Jpeg is uploaded, and we find Exif data, we will extract the data and insert it in the 'exif' field. We can't give any guarantees regarding retaining this data, changing the format of the data or taking pieces out.
id3
The id3 field will be used to store ID3 information from MP3's in the future. This is a planned feature.
user
Anything inserted in the 'user' field, will show up in the mediafactory. The mediafactory user is able to change this fields using this interface.
Example of interface on Media page in the MediaFactory:
transcoder
The last one in the list is 'transcoder'. This will be used in the future to give the transcoder specific instructions related to the transcoding process. The first two settings we intend to implement are cropping and rotation.
