    Web archiving using the collaborative archiving services testbed2011In: eChallenges e2011 Conference Proceedings / [ed] Paul Cunningham; Miriam Cunningham, IIMC International Information Management Corporation , 2011Conference paper (Other academic)
    Abstract [en]

    Websites constitute one category of official records and as such should be preserved for the long term in compliance with Swedish legislation. Collaborative Archiving Services Testbed (CAST) supports actors involved in the selective web archiving process, from harvesting to the creation of an information package ready for transfer to a long-term archive at National Archives of Sweden. CAST is developed in compliance with the ISO standards Open Archival Information System (OAIS) and Producer-Archive Interface Methodology Abstract Standard (PAIMAS), and do also consider other well-known and established standards and recommendations in digital preservation area. CAST promotes cooperation, knowledge acquisition and sharing among users in an experimental step-by-step workflow, encouraging a proactive approach resulting in authority websites better adapted to digital preservation recommendations. CAST is developed at LDP Centre, a national competence centre in Sweden, within the digital preservation area.

    Agent technology supporting digital preservation2009Conference paper (Refereed)
    Abstract [en]

    The EU FP7 PROTAGE project opens up a novel approach to digital preservation by utilizing agent ecosystems for automation of preservation processes. The resulting preservation tools have the potential to enable integrated automated digital preservation operations in digital archives and libraries of different scales throughout Europe. It could also assist individuals in preserving their personal digital collections. The PROTAGE multi-agent system, a set of integrated tools, is developed as a prototype system in several iterations. The first prototype contains functionality for pre-ingest, i.e. the preparation of information packages for transfer from active usage to a digital archive.

    Metadata for presentation / preservation of physical structure2008In: Proceedings of 31th Information Systems Research Seminar in Scandinavia: Public systems in the future : possibilities, challenges and pitfalls / [ed] Viveca Asproth, Mittuniversitetet , 2008Conference paper (Refereed)
    Abstract [en]

    This paper investigates support for presentation of physical structure in existing metadata schemas used in digital preservation. Physical structure in this case is entirely focused on visual attributes for digital objects, in particular web-forms of the kind that is beeing used in many eGovernment services. In order to spot gaps and problem areas, practical examples in the form of demonstrator objects is constructed using PREMIS, and to a lesser extent utilising METS behavior section. METS is also tried as a wrapper for PREMIS. The new version of PREMIS (2.0) is found to be useful, much depending on the more refined support (both related to earlier PREMIS and METS) for significant properties.

    Preserving logical and physical structure of information by "metadata driven imitation"2006In: Integrating Visions of Technology: Proceeding of the 12th Annual Working Conference of CPTS / [ed] Andrew Basden; Anita Mirijamdotter; Sytse Strijbos, CPTS , 2006, p. 91-102Conference paper (Refereed)
    Abstract [en]

    According to research in the area of digital preservation (Dollar 2000), logical and physical structure of a document/record are important to preserve in order to make the document understandable. In layman terms this means that the order and visual attributes of a document should be preserved. At the same time, exact copies of digital files can easily be made, but the problem then lies in that the original application is needed to render the document readable again. To make archived documents/records easily accessible and useable in the future with­out the need of their original application, I suggest that imitative copies with their logical and physical structure intact, are made. These can then easily be distributed to a wide audience (the public) for example through the web. In order to achieve this I suggest a "metadata-driven imitation" where metadata is used to describe the logical and physical structure of the document, preferably combined with a backdrop that holds static visual characteristics. For this purpose I have used a couple of different but complementing perspectives, namely; The Performance Model, The Open Archival Information System model, the Model-View-Controller framework and the Underlying Abstract Form. The outcome of this combination is "metadata-driven imitation", a general suggestion on how logical and physical structure can be preserved, thus providing the possibility to access the original docment/record as well as the possibility to process the data.

    Preserving physical structure of digital objects through metadata2006Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    In the wake of increased e-government service and overall increase in creation of digital documents, the problem of preserving this kind of "digitally born" material has become imminent. This research focus on how to preserve the physical structure, in other words the layout, colours, logotypes, font characteristics and so on, of digital objects. The reason for this lies in the interest of preserving the information of digital objects, which besides what usually is seen as the content, namely the text or numerical values represented in the digital object, also includes the visual attributes since they contribute to the information drawn from the data in the digital object (document/form). The suggestion posed in this work is that the visual attributes could be described with metadata and, where applicable, "backdrops" in order to make the future rendition of the digital object as similar to the original as possible. Since it is possible to make exact bit-level copies of digital objects, and since they are recreated every time they are accessed, I use the term "metadata driven imitation" to emphasize that were not really dealing with originals, but instead imitative copies. One important benefit of this is that the content still is searchable and accessible, instead of frozen in a document which content is readable for humans but not for machines.

    Preserving useful digital objects for the future2008Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis deals with the preservation and presentation of physical structure (i.e. visual appearance) of digital information objects. The research is focused on digital information objects of a character that is common in e-services and e-government, namely web forms or receipts that exists in large numbers with similar form. The reason for this is the increasing number of e-government services that will produce records that need to be preserved. The main proposition is that physical structure is important to preserve in order to facilitate interpretation of information objects. Another proposition is that this physical structure is possible to describe with metadata. These propositions were challenged, and the concepts of trustworthiness, understandability, accessibility, availability and usefulness were discussed empirically with information experts (archivists), system developers, experienced users (genealogists) and occasional users, around a demonstrator object as base for the discussions. The demonstrator object was developed in an iterative process during the thesis work, according to inputs from both literature and empirical studies, and eventually a minimized metadata description of physical structure was found. This minimized structure represents a compromise between original look and manageability in the preservation process, as well as desires from the users and experts queried during the research process. Not surprisingly, trustworthiness was found to be mostly a matter of documentation of the preservation processes and the history of the information object, and even if an "authentic look" slightly improved the feel of trust, it was only considered as a "false sense" of trust. Regarding usefulness, the separation of data from physical structure, and the ability to present the material in different forms was seen as useful by all categories of respondents. The demonstrator object showed that the separation worked out sufficiently well, and as intended, it was seen as a suitable approach to presentation of documents of a textual character that exists in large numbers with similar form. So, in short, keep data and physical structure separated for maximum usefulness and flexibility; find a middle way of re-presenting the physical structure for the type of document in question; document everything that the information object is subjected to, in order to provide both trust and usefulness to the future users.

    Preserving visual appearance of e-government web forms using metadata driven imitation2010In: Proceedings of the 7th International Conference on Preservation of Digital Objects / [ed] Andreas Rauber; Max Kaiser; Rebecca Guenther; Panos Constantopoulos, Wien: Die Österreichische Computer Gesellschaft, 2010, p. 257-260Conference paper (Refereed)
    Abstract [en]

    This paper summarizes work done in a PhD study on metadata driven imitation for preservation of visual appearance of web forms and/or receipts used in eGovernment services. The research done suggests that metadata, and e.g. a background image, can be used to describe the visual appearance of documents, and that this also facilitates having the data separated from the visual appearance. This separation provides the ability to present the material to the users in different ways, depending on their needs and requirements, while retaining the ability to present the object in its original look. The original look is seen as the most versatile way of presenting the material, giving the most fruitful base of interpretation and understanding, but if the users where familiar with the material, they liked the ability to have the material presented in simplified ways, where many of the sometimes "distracting" visual attributes where removed. In general, preserving the visual appearance and keeping the data separated from the form, was seen as useful and beneficial to both the users and the preservation professionals. As always in digital preservation contexts, documentation of this process and the relation between the metadata describing the visual appearance and the data of the document, is of high importance.

    Metadata driven presentation of records2007Conference paper (Refereed)
    Abstract [en]

    This paper discusses an approach to preserve presentation by using metadata to describe the ‘look' of digital documents in order to make them appear in a trustworthy way. The reason for making them appear in a trustworthy way is that documents often get record status, for example in a governmental agency. The concept of Records Continuum together with work conducted by Heslop, Davis and Wilson at National Archives of Australia regarding preservation of digital records, is some sources of inspiration for the approach suggested in this paper, together with discussions around significant properties and imitative copies. This paper focuses on discussing how metadata driven presentation of web-based forms can be a suitable way to preserve logical and physical structure of such forms, and in particular reason around a model suggested for this kind of preservation (Nilsson 2006). This is all part on an ongoing work and at the moment the focus lies on objects that are created digitally (i.e. does not have an analogue original). This paper only considers individual documents/forms/records and not records in the meaning of several digital objects that all are part of one record. The results, which are based on interviews with individuals in the archival community, point at that the suggested approach, despite some problems, could be a suitable way to handle the access to imitative copies of digital objects, but that this alone is not enough for achieving trust in the object.

    Concise preservation by combining managed forgetting and contextualization remembering2013Report (Other (popular science, discussion, etc.))
    Abstract [en]

    This report covers a systematic study of existing research literature on smooth bi-directional preservation transition between producers system (active system) and a Synergetic Preservation system. This transition is meant to be as transparent as possible to the user, and also be able to fetch material from the preservation system in a smooth way. The report also includes a study on gaps that could be identified from existing research and what this integration would need to cover, and how it conceptually could work in Content Management Systems (use case: Typo3) and Personal Information Management (use case: Semantic Desktop / PIMO). The report groups activities into three high-level workflows; Preservation planning and administration, Preservation, and Access and retrieval. In these workflows, the contextual preservation administration, which link the preservation and storage services to particular information systems and maintains the contextualized preservation and access workflows, interfaces and ontologies, is something that needs further development during the project, since it includes many of the project specific peculiarities. This also goes for the other components of the middleware, which also are contextually aware, and part of the "forgetting" approach. Both workshop results and the literature review shows that integration of these workflows with the producing workflows should be done in a way that makes it low-effort, generic, and transparent – which goes well together with what the project set out to do. Most likely some sort of automatic appraisal needs to take place already in the producing systems, and the challenge here would be to make it non-intrusive but effective. The ideas and results from this report will serve as a starting point for design and integration that will take place in WP5 of the ForgetIT project, in particular for T5.2 and T5.3 as well as D5.2. The ideas in this report are however not strict rules to be followed, and may be altered or improved as work continues in above mentioned tasks. Any such actions will be reflected in D5.2 or subsequent reports.

    Integrating Contemporary Content Management and Long-Term Digital Preservation: A Design Problem2015In: Nordic Contributions in IS Research: 6th Scandinavian Conference on Information Systems, SCIS 2015, Oulu, Finland, August 9-12, 2015, Proceedings / [ed] Harri Oinas-Kukkonen; Netta Iivari; Kari Kuutti; Anssi Öörni; Mikko Rajanen, Cham: Springer International Publishing , 2015, p. 92-107Conference paper (Refereed)
    Abstract [en]

    The fields of long-term digital preservation (DP) and enterprise content management (ECM) have remained, until recently, rather separated. Along with increasing amounts of digital content and evolving DP services, there is a need for maximal automation of preservation processes from ECM systems instead of continuing current resource-consuming practices. This paper aims at a design problem definition on the integration of ECM and DP solutions. In order to motivate and to define the problem in more detail, we conducted a review on ECM and DP literatures touching the issue. The review reveals a research gap addressing a need for designing new middleware solutions for interactive processes between ECM and DP. We suggest a general-level model of three such processes between ECM and DP: preservation administration, pre-ingest, and access. The article concludes with avenues for future research on novel solutions for integrating DP with contemporary ECM and other information systems in organizations.

    Administration of Digital Preservation Services in the Cloud Over Time: Design Issues and Challenges for Organizations2014In: The Proceedings of the 2nd International Conference on Cloud Security Management / [ed] Barbara Endicott-Popovsky, Reading, UK: Academic Conferences and Publishing International Ltd , 2014Conference paper (Refereed)
    Abstract [en]

    In organizations, information systems produce increasing amounts of digital information that needs to be preserved. Simultaneously, human intervention in preservation activities needs to be minimized, due to scarce resources available for preservation. Thus, digital preservation services need to be integrated with other organizational information systems as seamlessly as possible, and preservation activities need to be maximally automated. Selection of adequate cloud-based preservation services poses yet another set of challenges for reaching the seamless integration and automation. Two sources of challenges relate to administrating integrated digital preservation and information systems. Firstly, information systems change over time. Secondly, digital preservation services change over time. This paper contributes by identifying and analyzing scenarios and design issues of administering digital preservation in connection to the changes in information systems and preservation services over time. We also suggest seven generic tasks of the “preservation administration” component, which are needed between digital preservation services and information systems and discuss about the choices of locating the operative responsibilities and middleware.

    Inherent problems in cooperative planning for future access to information2013In: Norsk konferanse for organisasjoners bruk av informasjonsteknologi, NOKOBIT 2013: Universitetet i Stavanger, 18-20 november 2013 / [ed] Terje Fallmyr, Trondheim: Tapir Akademisk Forlag, 2013, Vol. 2013Conference paper (Refereed)
    Abstract [en]

    Successfully preserving information for the future draws upon multiple domains of knowledge, specifically knowledge about effects of technological and social change. The preservation process should accommodate for these effects in order to provide future access to the preserved information. If information production and information preservation occur in different organizations, such as when an organization uses external preservation services, special attention has to be given to the planning of the preservation process. Studies in the project ENSURE (Enabling kNowledge Sustainability Usability and Recovery for Economic value) indicate that the preservation planning is a joint effort drawing upon distinct knowledge that each organization have – knowledge about the information and knowledge about the preservation process. We describe some inherent problems emanating from cooperatively planning how to preserve information.

    Towards automated pre-ingest workflow for bridging information systems and digital preservation services2019In: Records Management Journal, ISSN 0956-5698, E-ISSN 1758-7689Article in journal (Refereed)
    Abstract [en]

    Purpose

    This paper aims to automate pre-ingest workflow for preserving digital content, such as records, through middleware that integrates potentially many information systems with potentially several alternative digital preservation services.

    Design/methodology/approach

    This design research approach resulted in a design for model- and component-based software for such workflow. A proof-of-concept prototype was implemented and demonstrated in context of a European research project, ForgetIT.

    Findings

    The study identifies design issues of automated pre-ingest for digital preservation while using middleware as a design choice for this purpose. The resulting model and solution suggest functionalities and interaction patterns based on open interface protocols between the source systems of digital content, middleware and digital preservation services. The resulting workflow automates the tasks of fetching digital objects from the source system with metadata extraction, preservation preparation and transfer to a selected preservation service. The proof-of-concept verified that the suggested model for pre-ingest workflow and the suggested component architecture was technologically implementable. Future research and development needs to include new solutions to support context-aware preservation management with increased support for configuring submission agreements as a basis for dynamic automation of pre-ingest and more automated error handling.

    Originality/value

    The paper addresses design issues for middleware as a design choice to support automated pre-ingest in digital preservation. The suggested middleware architecture supports many-to-many relationships between the source information systems and digital preservation services through open interface protocols, thus enabling dynamic digital preservation solutions for records management.
