Different tracks• To deal with data variability and heterogeneity, tracks are

defined.• These are built on the relation between digital objects and the

archival system, independently of any given organization: – Heritage digitization;– Audiovisual legal deposit;– Negotiated legal deposit (e-books, large posters…);– Automatic legal deposit (surface Web);– Administrative production;– Third party archiving;– Acquisition / Donation;+ reference track

A collaborative approach

• Skills are spread around the library and they are seldom

• First use in real life: positive feedback (though improvements needed)

• More visibility, not only admins have access to the system settings

• Providing a practical and operational framework
