This document focuses on the methods that will be used in the Testbed for testing tools for objects and tools for environments. It is not about software testing the testbed application itself. [PDF, 816KB]

This report gives a first evaluation of the current and future use of the Testbed software. This evaluation is given by the Planets partners who are participants in TB/3 and based on information gathered through means of a questionnaire. This report gives recommendations on the future deployment and use of the Testbed software. [PDF, 367KB]

This assessment report gives an evaluation of the usage by external users of the central Testbed software. This evaluation is based on a survey set out to 109 people that requested testing access to the Testbed. [PDF, 433KB]

This document is a guide to the Planets Testbed Prototype. It highlights what features are available in the Prototype and which parts of the system are not yet operational. [PDF, 1635KB]

This report seeks to investigate the classification of digital object properties for digital preservation, both in the context of the PLANETS project and in that of the wider digital preservation community. The report aims to address the diverse approaches employed when looking at classifying digital object properties and will, consolidate and summarise the different approaches and give recommendations for future work.

This report is part of a three-part final report from the PLANETS Digital Object Properties Working Group. The three companion reports, which can be read in conjunction, are:

• The concept of significant properties. (PLANETS deliverable PC3 – D23A (this report));
• Planets components for the extraction and evaluation of digital object properties (PLANETS deliverable PC3 – D23B); and
• Specification of a Planets-wide Ontology of properties for digital preservation needs. (PLANETS deliverable PC3 – D23C)

The National Archives of the Netherlands is the largest public archives in the Netherlands and the custodian of the national record of Dutch Government. Increasingly, these records are digital, and are being housed in the National Archive's custom-built e-Depot. Since 2002, the National Archives has carried out research into the feasibility of strategies to preserve different types of digital objects. This case study considers the appropriateness of emulation to preserve dynamic records such as spreadsheets and databases where migration is not a suitable option. [PDF, 525KB]

This paper discusses the Planets approach to migration tool development. The approach consists of enhancing existing migration tools rather than developing tools from scratch. This pragmatic approach is based on the Planets view of the current situation for migration tools and two claims. The first claim is that the market will cover the required tools for commonly used formats. The second claim is that in the long term less tools will be required due to growing use of archiving standard formats. The Planets view on the current situation, the scope of tool development and the claims stated are, however, open for discussion and re-evaluation.

The paper was presented at the IS&T Archiving 2008 conference in Bern, Switzerland. [PDF, 205KB]

Ross King, Austrian Research Centres GmbH, delivered this presentation at the Planning the Future with Planets tutorial at the Austrian Computer Society, Vienna on 14 April 2008. The presentation provides a technical outline of the thinking behind the Planets interoperability framework; the architecture which will make tools and services available via a single platform; an overview of the benefits. The presentation introduces the Planets Service and Data Registries and workflow design tools. [PDF, 925KB]

Hannes Kulovits (Vienna University of Technology) gave a presentation on the preservation tool Plato and the workflow related to preservation planning at the WePreserve Forum 2009 in Barcelona on 27 March 2009 [PDF, 1643KB]

This is a presentation by Max Kaizer given at the 2nd Planets, CASPAR and DPE annual conference, held on 5-6 September 2007 in Lisbon, Portugal. It explains what the testbed is, why we need it and its role within Planets and for the wider digital preservation community. It also explains in great detail the methodology that drives the experiment process within the testbed, as well as the components of the testbed software application. [PPT, 363KB]

Eleonora Nicchiarelli, Austrian National Library, delivered this presentation at the Planning the Future with Planets tutorial at the Austrian Computer Society, Vienna on 14 April 2008. The presentation describes why a testbed is needed, how the Planets Testbed works, and the role it plays in the project. [PDF, 99KB]

In this presentation Max Kaiser (Austrian National Library) explains the need for an experimentation framework for digital preservation and systematic assessment of preservation approaches and tools. The Planets Testbed provides a controlled research environment for evaluation of preservation tools wrapped and deployed in the Testbed. When using the Testbed Corpora one can perform experiments without having to expose the institution’s own content and at the same time one can share and browse knowledge obtained through experiments.
The presentation was delivered during the joint DPE/Planets/CASPAR/nestor training event, ‘The Preservation challenge: basic concepts and practical applications’ in Barcelona, 23-26 March 2009.

In his presentation Max Kaiser describes the Planets Testbed, which is a controlled environment for experimentation on and evaluation of a wide array of preservation tools and services. The full public release of the Testbed will be in 2010, but it is possible to get access to carry out experiments now and thereby to help improving the development of the Testbed.

This presentation was given by Max Kaiser from The Austrian National Library at the eChallenges e2009 Conference in Istanbul on 21-23 October 2009. [PDF, 474KB]

Abstract: "The preservation of digital objects requires specific software tools or services. These can be characterisation tools that abstract the essential characteristics of a digital object from a file, migration tools that convert digital objects to different formats, or emulation tools that render digital objects in their original context on a new infrastructure. Until recently digital preservation has been characterised by practices and processes that could best be described as more art and craft than science. The Planets Testbed provides a controlled environment where preservation tools can be tested and evaluated, and where experiment results can be empirically compared. This paper presents an overview of the Testbed application, an analysis of the experiment methodology and a description of the Testbed’s web service approach."

Hans Hofman, the National Archives of the Netherlands, gave a presentation on Plato and the use of objective trees in preservation planning at the DCC/DPE/DRIVER/nestor joint workshop on 28 November 2007 in Berlin, Germany.

The presentation presents the influencing and deciding factors that go into preservation planning, and the stages you have to go through in the process. It also presents both the "objective tree" and Planets Preservation Planning tool, PLATO. [PDF, 1171KB]

Abstract: "It has not been since the advent of the client/server architecture break through that an architectural concept has changed the face of enterprise systems so significantly as it has been done by service oriented architectures (SOA). The service oriented approach provides plenty of vantages for companies in regard to flexible system integration and adoption of new business cases. However, the adoption of SOA in an actual enterprise system brings along a couple of problems as well. Especially the integration into the existing infrastructure, applications and the innovation, sourcing and investment policies is challenging. A solution can be provided by establishing a SOA roadmap unveiling possible traps and pointing out the foibles and flaws still existing in the SOA approach. In this paper the SOA approach will be reviewed critically and the different sections affected within an enterprise will be examined. Possible problems during the transition and use of SOA will be identified. Where already possible, solutions will be provided."

The article was accepted for and presented at the 14th Annual IEEE International Conference and Workshop on the Engineering of Computer Based Systems, ECBS, in Tucson, AZ.
