The Metadata details information about your images. This information can be time consuming to generate therefore will be proteced the same ways the images are proteced.
This information is stored in the Metadata table and is stored along side the images in the Master repository. In the Master repository it is stored as a xml formated file one file per image. This is also is replicated in the Master backups. This enables redundancy. If the archive is demaged the Master can be regenerated from one of the backups and if the working Metadata table is demaged then this can be regenerated.

pi - csvdb

The Master Repositry Metadata
The Metadata files are stored in a parallel folder to the image folder called metadata. The xml file is named the same as the image file the Metadata is associated. The exetention xml is added to the Metadata file.
