Planets Partners

The Planets consortium brings together the unique experience required to research, develop, deliver and productise practical digital preservation solutions. Coordinated by the British Library, the partners are:


The British Library

The British Library is one of the greatest research libraries in the world and manages an extraordinary challenge in terms of preservation and provision of access to materials. In 2003-2004, we provided over 5,320,000 items and received more than 395,000 visitors in our reading rooms; we created over 490,000 digital images, and delivered over 4,700,000 pages of digital material over the web; our collections span over 11,200,000 monographs, 10,115,000 reports in microform, and 836,000 serial titles. As we pursue our mission to help people advance knowledge to enrich lives, we underpin the UK�s contribution to world-class research, scholarship and business innovation.

The National Library of the Netherlands

The National Library of the Netherlands, was the first national library in the world to have an operational digital deposit system based on the OAIS model. The digital archiving system is called the e-Depot and contains the DIAS-system (Digital Information Archiving System) as its technical core. DIAS was built by IBM in close co-operation with KB and has been operational since March 2003. The system was built according to the recommendations that were made by the partners of the EC-funded project NEDLIB. KB has an agreement with most of the key international publishers in the field of SMT (Science, Medicine and Technology) including Elsevier, Springer and BioMed Central to have their online journals archived for long term preservation and access in the e-Depot. Since 2003, IBM and KB continued working together to develop new preservation functionality for the e-Depot, which resulted in the Preservation Manager (a file format registry), and a working prototype of the Universal Virtual Computer (UVC). In 2005 KB has started a joint project with the Nationaal Archief of the Netherlands to build an emulator for digital preservation.

Austrian National Library

The Austrian National Library is the main scientific library of the Republic of Austria with a history rich in tradition dating to the 14th century. It offers access to and professionally competent advice on its own holdings (around 7.5 million objects) and links to international electronic resources and digital library services. The Library is required by media law to receive a copy of every publication appearing in Austria, including university theses and (offline) electronic publications. ONB currently participates in a national working group for legal deposit regulation for online publications as well.

The Library is committed to preserve a variety of digital material including deposited electronic (online and offline) publications in various formats, electronic theses, e-prints, offline media on various carriers, digital surrogates emerging from large-scale in-house digitisation projects and material resulting from web harvesting. The Library is a national focal point for digital preservation in Austria and recently organized the UNESCO conference "Long-Term Preservation in the Digital Age" in March 2005. ONB is also co-organizer of a "Chinese-European Workshop on Digital Preservation" (Beijing, July 2004) and the International Conference on Preservation of Digital Objects and the European Conference on Research and Advanced Development for Digital Libraries, both in September 2005.

The Royal Library of Denmark

The Royal Library of Denmark is a National Library with the obligation to preserve Denmark�s digital cultural heritage for future use. It is also a university library preparing to undertake the role of an institutional repository. International cooperation, e.g. IIPC (International Internet preservation coalition), is one of the ways the library tries to be at the cutting edge of digital preservation research and development. Also, staff from KB-DK tries to be represented at conferences and workshops dealing with all aspects of digital preservation.

State and University Library, Denmark

The State & University Library, Denmark, has four roles, it is the university library of Aarhus University, it is a national library with main responsibility for the national newspaper collection, it hosts the national media archive (sound recordings, radio & TV) and finally it is the national loan centre for public libraries and small special libraries. As a result of a new legal deposit law effective from July 2005 the library has started two initiatives, it has started to digitise radio and television material broadcasted in Denmark in real time and together with the Royal Library (KB-DK) it has started to archive the Danish Internet content.

As a result of these two new initiatives, the library expects to add 100 TB of data per year. The library is also engaged in digitising its audio collection; it currently holds close to 200.000 sound tracks. Finally, SB runs an institutional repository for the University and is conducting research into life cycle management for research and teaching material. Initiatives have been taken in the area of bit- and functional digital preservation. The web-archiving system focuses on ensuring bit preservation through hardware redundancy, ensuring trust, and supporting a migration-based digital preservation strategy. Together with the Danish Royal Library, it has established a shared IT development group consisting of 10 computer scientists working in the area of web-archiving and digital preservation. The group also has established expertise in user-centred design and user involvement and is presently in charge of a national project aiming at identifying where in the researches working process the library fits in - either as embedded resources or as a physical place.

The National Archives of the Netherlands

The Dutch National Archives has been involved in digital preservation since the beginning of the 1990s. It has a legal duty to provide access to and preservation of archival records through time, both paper and digital. It has longstanding experience managing and preserving paper records. It provides access to government records and other historical sources to a broad audience, also by using modern channels such as the world wide web. The Archive has been involved in development of a preservation testbed since 2000, the start of a joint venture with the Ministry of the Interior. This work has continued through into DELOS and a project on emulation in cooperation with the Dutch National Library.

The National Archives of England, Wales, and the United Kingdom

The UK National Archives is responsible for looking after the records of central government and the courts of law, and making them available to everyone. The collection is one of the largest in the world and spans an unbroken period from the 11th century to the present day.

The Archives advises government departments and the wider public sector on best practice in records management as well as selecting government records of enduring historical value which will be preserved forever. One of the Archives� major achievements in the past few years has been the development of electronic records management, which will replace paper-based systems. It is at the forefront of this advance and will continue to develop it and advise others on its use.

The Archives has also pioneered the digitisation of records on paper and other traditional media so that they now can be seen online. It is a leading institution in the field of digital preservation with a digital archive capacity of 100 TB for storage of born-digital public records. It has also established the innovative PRONOM service, a technical registry to support long-term preservation. In 2004, the Archives was awarded the first Pilgrim Trust Award for Digital Preservation, in recognition of its work in developing its digital archive.

Swiss Federal Archives

The Swiss Federal Archives (BAR) is the memory of the Swiss Federation. In accordance with the Swiss federal law on archiving, the BARs mission is to preserve, make accessible and evaluate valuable federal records. It documents the origin and development of rights and freedoms and ensures that governmental activities are transparent. In addition, its archives provide a foundation for historiography, permit insight into the present from the past, and contribute to shaping the future.

The BAR has a long record of activity in the field of electronic records preservation. In particular, the first phase of its ARELDA project (2000-2004) laid the groundwork for successful digital preservation of relational databases by establishing the basic concepts and infrastructure. Currently, the second phase of ARELDA (2005-2008) is set to implement a reliable digital preservation solution embedded in the Archives� workflow and processes. This phase will include pilot projects implementing the archiving of relational databases and research on preserving complex records management systems.

University of Cologne

University of Cologne
UzK is Germany's largest university with 58.000 students. The University has recently established a research focus in Media Studies, which includes a degree program and research institute in Computer Science for the Humanities. The main applied research activities include a focus on various aspects of digital library systems. Software developed and maintained by the Department supports some of Germany's largest (cultural heritage) digital libraries. It has just completed a major evaluation project of the German national digitization projects, supported by the National Research Council since 1997, leading to detailed recommendations for the next round of national funding. Research into non-relational / native XML / multi-media databases has resulted in the development of a vast heterogeneous database backbone ("Prometheus") funded by the German federal ministry of research for a pilot project testing the possibilities of a virtually unified server uniting the image collections of all German art history departments.

University of Freiburg

University of Freiburg hosts the research group for communication technologies, which is involved in Planets. The group addresses numerous questions with respect to long term archiving. It is stimulated both from the activities in the computer science department and the responsibilities derived from the reliable services of a computer centre. The research group focuses on the concept of hardware emulation to preserve environments for a wide range of different digital objects. Very dynamic and interactive objects like spreadsheets, multimedia, elearning, audio, video streams and games are extremely challenging regarding long time preservation. It is not enough just to keep the physical file intact, but to provide environments consisting of (virtual) hardware and software to access them.

The group has also significantly contributed to political decisions in the German library scene as Gerhard Schneider is a long term member of the library commission of the "Deutsche Forschungsgemeinschaft (DFG)". He is chairman of several of its sub-commissions and member of the administrative board of the "Deutsches Forschungsnetz (DFN)". He also serves as CIO and vice president of the University of Freiburg.

Technology Companies

Austrian Institute of Technology (AIT)

The Austrian Institute of Technology (AIT) is Austria�s leading research and technology establishment and a key player on the European research landscape where the exchange of knowledge with universities and companies is central to the successful development of industry. AIT conducts research to underpin the competitiveness of Austria in an international context. A total of around 1.200 employees located at 14 sites across Austria, with the main facilities in Seibersdorf, Lower Austria, and in Vienna, act as technology providers and innovation partners to society, industry and commerce. The institutionalised technology transfer services provided by AIT are critical to the successful transfer of know-how and do-how, and they also take account of the interests of SMEs. AIT realises future-shaping solutions through its role as an interface between research-based and commercial companies. A further indication of AIT�s international competitiveness can be seen in the Group�s intensive involvement in the research and technology programmes of the European Commission, a context in which the Austrian Institute of Technology cooperates with other European research institutes and companies to establish new partnerships. This is an important means of exchanging application-oriented scientific findings with other stakeholders. The AIT Department of Safety and Security, responsible for work in the Planets project, is also involved in numerous EU-funded projects (COOPERS, TELplus, EuropeanaConnect), including as the coordinator of the S@NY (Sensors Anywhere), SECOQC (Development of a Global Network for Secure Communication based on Quantum Cryptography) and SENSE (Smart Embedded Network of Sensing Entities) projects.

IBM Netherlands

IBM Netherlands
IBM�s effort in Planets is concentrated around the Universal Virtual Computer (UVC). IBM had been actively developing the UVC concept for the last 5 years. The UVC concept has delivered numerous proof of concepts to preserve static data formats. IBM is starting to extend the application of the UVC concept to preserve more complex objects by exploiting its abstract communication facility (between the UVC program and a future new application). IBM believe this new way of using the UVC greatly extends its usage as a preservation tool for complex object dependent upon associated application logic.

IBM has a long working history with European libraries and archives. The most renowned is the Digital Information Archiving System (DIAS) developed by IBM as the core of the KB's e-Depot. Currently DIAS version two is being prepared to be deployed at Die Deutsche Bibliothek (DDB) and the Nieders�chsische Staats- und Universit�ts Bibliothek G�ttingen (SUB).

IBM has 3000 researchers in eight labs around the world. Developing and supporting industry standards has always been one of the main objectives of IBM. A few recent examples of IBM's contribution towards setting the standards are Linux, WebSphere, XML and Eclipse. The focus for IBM Nederland is to continue to be a critical part of IBM's success by balancing projects that have an immediate impact with those that are long-term investments. IBM's research network can provide extensive inside information during the project as well a possible target group in the dissemination of the Planets project.

Microsoft Research Limited

Microsoft Research Limited
Microsoft Research involvement in Planets is focussed on identifying strategies for using Office Open XML standards for archiving and preservation of digital content. The Microsoft Office Open XML (Office Open XML) formats represent a significant advance in representing information contained in textual documents, spreadsheets, and multimedia presentations in an open format, based on the XML standard. Microsoft believes that the use of the Microsoft Office Open XML formats can maximize long-term usage of documents and provide the value to the organisations and services concerned with archiving and preservation.

Microsoft Research (MSR) was established in 1991 and has since developed into a unique entity among corporate research labs, balancing an open academic model with an effective process for transferring its research to product development teams. Microsoft researchers work across more than 55 disciplines, including areas that are directly related to the authoring, management, metadata creation, access security, and analysis of digital documents. Although most of the researchers pursue long-term goals that extend far beyond the current product cycles, they also work closely with product groups to transfer knowledge and help turn their discoveries into functional offerings. Thus, through Microsoft Research participation, the Planets project will be able to consult with Microsoft researchers on important research and technology issues and gain contact with key product groups who can contribute to defining the global strategy for preservation.
