Metadata (n): Data about data.
Metadata includes basic file infomation, e.g.:
- Filename
- File ownership
- File permissions
However, metadata can be any other piece of information about stored data, which aids a user in handling it, describing it and understanding what it contains. In the LCG context this means experimental metadata such as:
- Data set membership
- Data type (RAW, tracks, calibration)
- Associated processing applications
There's a good deal more information in the GridPP Metadata Wiki.
