Tidskriftsartikel (refereegranskat)abstract
- Purpose – The purpose of this paper is the automation of an error-handling workflow that, in case of failures, will take over a pre-ingest workflow which is originally designed for preserving digital content through a middleware for many-to-many interactions between Information Systems and Digital Preservation Systems.Design/methodology/approach – A Design Science Research (DSR) approach is taken resulted in a model and proof-of-concept for an automatic error-handling workflow with compensation action. The proof-of-concept was demonstrated and evaluated through several simulation scenarios.Findings – This study pinpoints the elements of consideration in designing a workflow for maximally automating handling of failures in a pre-ingest workflow. The error-handling workflow automatically takes over the original workflow and executes a backward path to compensate for the side-effects of components that have processed digital content before the failure occurred. The proof-of-concept, demonstrated and evaluated, verifies the technological feasibility of implementing the model. The evaluation of the model shows a considerable reduction in manual work and its complexity for handling errors. Three design principles are proposed as a contribution to the knowledge of design to afford a similar purpose. Originality/value – The approach introduced in this study for automatic error-handling in a pre-ingest workflow has not yet been applied in existing solutions.

Handling of Errors in Context-Aware Preservation Manager using Saga Patterns
- 2018
-
Konferensbidrag (refereegranskat)abstract
- In the field of Digital Preservation, rapid growth of digitized data has made the need for an automatic process to perform digital preservation tasks undeniable. One of the solutions to maximally automate interaction between Information Systems and Digital Preservation Systems is involvement of a middleware between the two systems. However, the middleware calls for human interaction in case an error occurs during a workflow within the middleware. This article suggests a workflow for automatically handling errors in the pre-ingest workflow in the middleware. Moreover, in this article, information on the implementation of such workflow will be provided and contributions of this workflow to the existing model of middleware will be pointed out.

Konferensbidrag (refereegranskat)abstract
- 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.

Designing for Automated Digital Preservation : Model, Pre-Ingest, and Error Handling
- 2020

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- With the rapid increase in the amount and complexity of data that is needed to be preserved, manual preservation activities produce complex, lengthy, and costly processes. Therefore, automation of preservation processes, together with modeling of workflows and streamlining, can help reduce costs and enhance the focus on preservation processes. Accordingly, the research question is defined as: “How to establish an automated many-to-many interaction between Information Systems and digital preservation systems?”This research proposes a model and instantiation of middleware as a standalone system, which could be hosted in the cloud, for bridging between ISs and DPSs including three sub-parts making both many-to-many capacity and automation of interactions possible: pre-ingest workflow, Context-aware Preservation Manager (CaPM), and error-handling workflow. A Design Science Research (DSR) approach was taken to conduct this research consisting of three design cycles to design and develop each of the three sub-parts of the solution artifact, i.e. the middleware. The middleware consists of several action-based components and an administrative component (CaPM) which carries out the automation of the tasks in the middleware. The action-based components are designed to complete a pre-ingest workflow to prepare digital content sent from an information system to be transferred into a digital preservation system. The path for the pre-ingest workflow, i.e. which components are going to process the digital content and in what order, is automatically defined by CaPM according to the information system’s preservation policies. Standard interfaces are used for middleware’s internal or external communications to promote its scalability in the long run as well as its capability of embedding additional workflows or processes developed in the future, e.g. post-access workflow.An additional outcome of this research is proposing five design principles aiming to contribute to the knowledge for future design practices: DP1. Provide rule-based definition of workflow execution path so that the middleware affords IS to implement their preservation policy and metadata extraction requirements. DP2. Provide capability of executing alternative workflow routes so that the middleware affords IS to ensure a successful encapsulation and submission of SIP. DP3. Provide features for gathering preservation data in the middleware so that the middleware affords preservation planning support. DP4. Provide an automated error-handling workflow with compensating action so that the middleware affords to minimize manual intervention in case of errors in a workflow. DP5. Provide capability of executing concurrent workflows so that the middleware affords IS and DPS many-to-many interactions via the middleware.The results of this thesis contribute to the state-of-the-art in a few aspects:Compared to existing solutions, such as pre-ingest tool developed for Finnish National Archives and UAM for Estonia, that need to be installed on a user’s system, integration with the middleware is carried out with less complexity. This is achieved by designing the middleware as a standalone system that could be hosted in the cloud along with using standard communication interfaces, which further make the middleware adaptable to changes or upgrades in the environment it operates in. Such capability of the middleware in handling many-to-many interactions goes beyond what was introduced in previous middleware architectures for Digital Preservation System’s integration with Information Systems.The middleware solution for pre-ingest in this thesis, in comparison with the similar recent solutions, promotes automation capabilities especially for preserving complex digital content (e.g. databases, workflows), automatic execution of the pre-ingest workflow, or in case of a need for using multiple external digital preservation solutions or services.CaPM monitors the execution of workflows and can update or abort a workflow path if needed. An aborted workflow caused by an error/failure will automatically be replaced by an error-handling workflow with compensation action, hence increasing the level of automation. Automation of such functionalities, as well as the approach for handling errors, has not been applied in previous tools.CaPM can also contribute to the current stream of research on decisions making regarding preservation planning and strategies by providing logged data about the digital objects passing through the middleware.While the solution artifact of this research provides middleware to perform as a bridge for automated many-to-many interactions between information systems and digital preservation systems, the resulted design and implementation of the middleware components cover only one direction of such interaction, from information system to digital preservation system (pre-ingest).

Towards Automated, Context-Aware Management of Preservation Submissions
- 2018
-
Konferensbidrag (refereegranskat)abstract
- Research in digital preservation field has realized the need for au-tomation of digital preservation activities. Without automation, the preservation of digital entities will be a complex and labor-intensive task. A middleware con-cept has been introduced by scholars to support automation of interactions be-tween content management systems and digital preservation systems. To boost the automation of workflows in the middleware, we introduce a component within the middleware, namely Context-aware Preservation Manager (CaPM), which is in charge of administration of the inner components of the middleware and the workflows for bi-directional interactions between content management systems and digital preservation systems. We describe the specifications of the Context-aware Preservation Manager and depict its inner components. Further, we explain about the processes that are improved, supported or can run automat-ically as a result of functionalities of Context-aware Preservation Manager.

Tidskriftsartikel (refereegranskat)abstract
- PurposeThis 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/approachThis 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.FindingsThe 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/valueThe 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.
