Construcción de un archivo a largo plazo para datos culturales

Digitization projects allow people to access large volumes of data online. The DigiBern project, for example, is an online portal where you will find information about the history and culture of the city and canton of Bern. It was created by the University Library of Bern. Even in this exemplary case, it is clear that libraries have to perform more tasks completed after a digitization project to ensure that data remains available long term. As data is spread across various storage media, and saved manually once, you need to perform quality checks to verify that remain legible and intact.

Security and long-term usability

The E-Rare project , a platform for Swiss printed works digitized libraries, works similarly. The University Library Berne is required to archive the data in the long term but long ago could not guarantee this process. The expansion of the institutional repository BORIS for university publications also brought the need to find a solution to ensure that these data remain safe and are used for several years in the future.

With all this in mind, the library joined the long term for the first time in its strategy for the period 2013-2016 the new challenge of digital file.

SWITCHengines helps the University Library Berne to create this long-term archiving.

¿Derive construction processes and execution?

In the planning phase, several options were evaluated to implement the digital file, and one of the key questions was whether it would be possible to derive a large part of the construction process and execution. He eventually decided to build a file on the premises of the library one step at a time. By having few resources and have to acquire the necessary skills as they progressed, it was decided that a pilot file is installed in an initial three-year phase first. Then there was a long debate on the requirements of a digital file and possible solutions and finally the implementation work began in 2015.

The tasks of the library after making the digitization process, as mentioned above, they had two different leads: SWITCH who had the responsibility to provide a central platform for data storage and Baden-based docuteam who took care to ensure data quality and long-term access.

adaptability key

One of the most important for the file from the point of view of the library requirements is that it must be oriented to have continuity and firmly integrated into its infrastructure and services. In this way, it is assured that it will be reliable and sustainable. Even if, in the first stage, only a limited volume of data is archived, the system must be adaptable and able to handle future demands such as the preservation of research data. Another objective is to ensure and document the results of university research to ensure that they can use and get smoothly in the future.

The digital archive of the University Library Berne is based on an internationally recognized reference model, the open file information system (OAIS, ISO 14721). The system comprises a standard OAIS information model where technical data and metadata to be integrated into the digital resources so that they can keep and use long-term specified. It also includes a functional model that determines the technical and organizational to perform tasks in a digital file. The standard system was very useful to design the digital file and also serves as a support for the technical implementation and its future implementation.

minimize risks

The system uses open source software for docuteam can collect and prepare data with the software Fedora Commons repository, which also features an open – source license. SWITCHengines is used to run the necessary servers and store data. In fact, in the first place was this new infrastructure that enabled the construction of the file step by step. When resources are being used and the minimum test file may be extended in the coming months without the library you need to worry about infrastructure problems. This new flexible SWITCH service also makes it possible to minimize risks in IT projects.
