Digital objects require appropriate measures for digital preservation to ensure that they can be accessed and used in the near and far future. While heritage institutions have been addressing the challenges posed by digital preservation needs for some time, private users and SOHOs (Small Office/Home Office) are less prepared to handle these challenges. Yet, both have increasing amounts of data that represent considerable value, be it office documents or family photographs. Backup, common practice of home users, avoids the physical loss of data, but it does not prevent the loss of the ability to render and use the data in the long term. Research and development in the area of digital preservation is driven by memory institutions and large businesses. The available tools, services and models are developed to meet the demands of these professional settings.This paper analyses the requirements and challenges of preservation solutions for private users and SOHOs. Based on the requirements and supported by available tools and services, we are designing and implementing a home archiving system to provide digital preservation solutions specifically for digital holdings in the small office and home environment. It hides the technical complexity of digital preservation challenges and provides simple and automated services based on established best practice examples. The system combines bitstream preservation and logical preservation strategies to avoid loss of data and the ability to access and use them. A first software prototype, called Hoppla, is presented in this paper.
Abstract. The creation of a concrete plan for preserving a collection of digital objects of a specific institution necessitates the evaluation of available solutions against clearly defined and measurable criteria. This process is called preservation planning and aids in the decision making process to find the most suitable preservation strategy considering the institution's requirements, the planning context and available actions applicable to the objects contained in the repository. Performed manually, this evaluation promises to be hard and tedious work, inasmuch as there exist numerous potential preservation action tools of different quality. In this demonstration, we present Plato [4], an interactive software tool aimed at creating preservation plans. PlatoThe preservation planning tool Plato 1 implements the PLANETS 2 Preservation Planning approach [3] which provides an approved way to make informed and accountable decisions on which solution to implement in order to optimally preserve digital objects for a given purpose. The tool is integrated into the PLANETS Interoperability Framework based on open J2EE and web technologies. This environment guarantees loose coupling of services and registries for preservation action and characterisation through flexible discovery and invocation.For format identification and property extraction, services such as DROID 3 and JHove 4 are used; based on this information, Plato discovers applicable action services such as emulation tools or migration services provided by CRiB [2] through available registries. Comparison and validation of objects as an essential feature of the system maps the specified requirements such as essential object characteristics to measurable criteria that can be compared automatically. Thereby, it considerably improves the repeatability, documentation, and automation of preservation planning.To not impose any technical restrictions on the user Plato has been developed with very close attention to the web user interface when determining the 1 http://www.ifs.tuwien.ac.at/dp/plato 2 http://www.planets-project.eu
Creating a concrete plan for preserving an institution's collection of digital objects requires the evaluation of available solutions against clearly defined and measurable criteria. Preservation planning aids in this decision making process to find the best preservation strategy considering the institution's requirements, the planning context and possible actions applicable to the objects contained in the repository. Performed manually, this evaluation of possible solutions against requirements takes a good deal of time and effort. In this demonstration, we present Plato, an interactive software tool aimed at creating preservation plans.
Digital information is of crucial value to a range of institutions, from memory institutions of all sizes, via industry and SME down to private home computers containing office documents, valuable memories, and family photographs. While professional memory institutions make dedicated expertise and resources available to care for their digital assets, SMEs and private users lack both the expertise as well as the means to perform digital preservation activities to keep their assets available and usable for the future. This demo presents the Hoppla archiving system 1 providing a digital preservation solution specifically for small institutions and small home/office settings. The system combines bit-stream preservation with logical preservation. It hides the technical complexity and outsource required knowledge and expertise in digital preservation.
