Version management YesDeposited datasets are stored as original. Data managers will publish the curated version. Updates will be stored as new datasets, linked to the old datasets.
Quality control Upload of datasets into the archive is automated by EASY. The process of data cleaning and metadata enrichment is mostly done manually, partially supported by existing tools and scripts. All sorts of security aspects are continuously being monitored by the DANS security officer as well as the security officer of the KNAW ICT service I&A.
Access requirements "User definable access rights;
- Open Access (CC-ZERO or direct access for registered users);
- Restricted Access (access to users registerd to a specific user group or access after permission by depositor). Access can be restricted to registered archaeologists.
- Other Access (data available elsewhere). 
Costs for Deposits or for Access are in implementation. Based on the Activity Based Cost Model, in combination with the Balanced Score Card Method."

Long term guarantees DANS has a mission for long term preservation.

Preservation strategy Migration strategy combined with preferred formats.
Storage "DANS is in overleg met de archeologische community over doorberekening van de opslag kosten. Deze kosten zijn gelijk aan die van EASY:

De kosten die DANS rekent voor data in EASY (excl. BTW):
- Opslag van data (toegankelijk via EASY): € 1,44 GB/jaar.
- Archivering van data (niet toegankelijk via EASY): € 0,48 GB/jaar.
- Back-up van data: € 1,14 GB/jaar.

DANS rekent een afkoopbedrag van 5 maal de jaarprijs ineens. Voor permanente toegang via EASY met backup rekent DANS dus eenmalig: (1,44 + 1,14) * 5 = €12,90/GB

(DANS maakt voor de opslag gebruik van de IT-dienstverlener Vancis.)"
Access Access is free.
Preservation De klant betaalt eenmalig voor een periode van 5 jaar de kale opslag kosten. DANS draagt daarna de kosten voor de lange termijn opslag.
Special conditions
Agreements with Leiden University UBL and DANS agreed on a cooperation between front-office and back-office.
