The development of large scale archive services is underway
. The archival service will be delivered through the bwDataArchiv project that provides:
- An easy-to-use interface for deposit, retrieval and update of scientific data
- Access to files via persistent URLs known as persistant identifiers (PID).
- Access to collections (groups of files) can be open or available to depositors only (644 or 600)
In due time it is planned to offer additionally:
- Support for specific file types and raw data
- Permanent storage with tools for long-term management of data content (aka curation)
How do I use the archive service and what does it offer?
The UK based Digital Curation Centre has drafted a checklist to help decide where to store research data. It can be found here []
At first the LSDF Archive Service offers bit stream preservation. This form of preservation is concerned with the maintenance of existing manifestations of a digital resource. Its function is to ensure the continuing integrity of, and controlled access to, the digital objects which are contained within the LSDF storage environment, including their associated metadata. It is sometimes referred to as passive preservation contrary to the “content preservation”.
We will make sure that your information is accessible only to those authorized to have access and is that it is protected throughout its lifecycle. Furthermore integrity checks will ensure that data is complete and unaltered [ISO/DIS 13008 – ISO 15489-1:2001]
Several projects have started to build reliable LSDF archive services. Research for large scale data management at KIT is contributing to the development of efficient and secure long time storage of petabytes of data. In the programme Supercomputing and Big Data of the Helmholtz Association the close collaboration with a multiple scientific communities resulted in clear requirements for future data management including the need to archive big datasets along with tools for provenance and curation. The archival projects at KIT strive to offer a reliable, dependable and above all easy to use service for scientists.

- RADAR - archival service for the long tail of scientific data
- bwDataDiss - service for scientific data from publications.
- bwDIM - enhancement of archive services and support
Research and development
What else? The long-term vision is a standardization of preservation services and interfaces. See here for a collection of interfaces to tape storage. The implementation of these services is not ready but many such services, or component services which can be brought together to produce the required results, already exist at the LSDF.
In addition we seek to guarantee that trust in the quality of the services is quantified using reproducible preservation metrics.

|Difference between a backup and an archive||backups are created for the express purposes of data restoration and continuity of operations in an emergency. Archives, are a means for long-term storage of scientifically or historically important data which require no immediate access.|
|Difference between an archive and a repository||there is none, although one usually refers to an archive if it is institutional e.g. the 'national archive'|
