The application of workflows to digital heritage systems

Digital heritage systems usually handle a rich and varied mix of digital objects, accompanied by complex and intersecting workflows and processes. However, they usually lack effective workflow management within their components as evident in the lack of integrated solutions that include workflow components. There are a number of reasons for this limitation in workflow management utilization including some technical challenges, the unique nature of each digital resource and the challenges imposed by the environments and infrastructure in which such systems operate. This thesis investigates the concept of utilizing Workflow Management Systems (WfMS) within Digital Library Systems, and more specifically in online Digital Heritage Resources. The research work conducted involved the design and development of a novel experimental WfMS to test the viability of effective workflow management on the complex processes that exist in digital library and heritage resources. This rarely studied area of interest is covered by analyzing evolving workflow management technologies and paradigms. The different operational and technological aspects of these systems are evaluated while focusing on the areas that traditional systems often fail to address. A digital heritage resource was created to test a novel concept called DISPLAYS (Digital Library Services for Playing with Antiquity and Shared Heritage), which provides digital heritage content: creation, archival, exposition, presentation and interaction services for digital heritage collections. Based on DISPLAYS, a specific digital heritage resource was created to validate its concept and, more importantly, to act as a test bed to validate workflow management for digital heritage resources. This DISPLAYS type system implementation was called the Reanimating Cultural Heritage resource, for which three core components are the archival, retrieval and presentation components. To validate workflow management and its concepts, another limited version of these reanimating cultural heritage components was implemented within a workflow management host to test if the workflow technology is a viable choice for managing control and dataflow within a digital heritage system: this was successfully proved

Preparing to Preserve: Three Essential Steps to Building Experience with Long-Term Digital Preservation

Many organizations face complex questions of how to implement affordable and sustainable digital preservation practices. One strategic priority at the University Libraries at the University of Nevada-Las Vegas, United States, is increased focus toward preservation of unique digital assets, whether digitized from physical originals or born digital. A team comprised of experts from multiple functional library departments (including the special collections/archives area and the technology area) was established to help address this priority, and efforts are beginning to translate into operational practice. This work outlines a three-step approach: Partnership, Policy, Pilot taken by one academic research library to strategically build experience utilizing a collaborative team approach. Our experience included the formation of a team, education of all members, and a foundational attitude that decisions would be undertaken as partners rather than competing departments or units. The team’s work included the development of an initial digital preservation policy, helping to distill the organizational priority and values associated with digital preservation. Several pilot projects were initiated and completed, which provided realistic, first-person experience with digital preservation activities, surfaced questions, and set the stage for developing and refining sustainable workflows. This work will highlight key activities in our journey to date, with the hope that experience gained through this effort could be applicable, in whole or part, to other organizations regardless of their size or capacity

Business Process Risk Management and Simulation Modelling for Digital Audio-Visual Media Preservation.

Digitised and born-digital Audio-Visual (AV) content presents new challenges for preservation and Quality Assurance (QA) to ensure that cultural heritage is accessible for the long term. Digital archives have developed strategies for avoiding, mitigating and recovering from digital AV loss using IT-based systems, involving QA tools before ingesting files into the archive and utilising file-based replication to repair files that may be damaged while in the archive. However, while existing strategies are effective for addressing issues related to media degradation, issues such as format obsolescence and failures in processes and people pose significant risk to the long-term value of digital AV content. We present a Business Process Risk management framework (BPRisk) designed to support preservation experts in managing risks to long-term digital media preservation. This framework combines workflow and risk specification within a single risk management process designed to support continual improvement of workflows. A semantic model has been developed that allows the framework to incorporate expert knowledge from both preservation and security experts in order to intelligently aid workflow designers in creating and optimising workflows. The framework also provides workflow simulation functionality, allowing users to a) understand the key vulnerabilities in the workflows, b) target investments to address those vulnerabilities, and c) minimise the economic consequences of risks. The application of the BPRisk framework is demonstrated on a use case with the Austrian Broadcasting Corporation (ORF), discussing simulation results and an evaluation against the outcomes of executing the planned workflow

The complexities of managing historic buildings with BIM

Purpose The adoption of building information modelling (BIM) in managing built heritage is an exciting prospect, but one that presents complexities additional to those of modern buildings. If challenges can be identified and overcome, the adoption of historic BIM (HBIM) could offer efficiencies in how heritage buildings are managed. Design/methodology/approach Using Durham Cathedral as a case study, we present the workflows applied to create an asset information model to improve the way this unique UNESCO World Heritage Site is managed, and in doing so, set out the challenges and complexities in achieving an HBIM solution. Findings This study identifies the need for a better understanding of the distinct needs and context for managing historic assets, and the need for heritage information requirements (HIR) that reflect this. Originality/value This study presents first-hand findings based on a unique application of BIM at Durham Cathedral, a UNESCO World Heritage Site. The study provides a better understanding of the challenges and drivers of HBIM adoption across the heritage sector and underlines the need for information requirements that are unique to historical buildings/assets to deliver a coherent and relevant HBIM approach

Unmanned Aerial Vehicle (UAV) for monitoring soil erosion in Morocco

This article presents an environmental remote sensing application using a UAV that is specifically aimed at reducing the data gap between field scale and satellite scale in soil erosion monitoring in Morocco. A fixed-wing aircraft type Sirius I (MAVinci, Germany) equipped with a digital system camera (Panasonic) is employed. UAV surveys are conducted over different study sites with varying extents and flying heights in order to provide both very high resolution site-specific data and lower-resolution overviews, thus fully exploiting the large potential of the chosen UAV for multi-scale mapping purposes. Depending on the scale and area coverage, two different approaches for georeferencing are used, based on high-precision GCPs or the UAV’s log file with exterior orientation values respectively. The photogrammetric image processing enables the creation of Digital Terrain Models (DTMs) and ortho-image mosaics with very high resolution on a sub-decimetre level. The created data products were used for quantifying gully and badland erosion in 2D and 3D as well as for the analysis of the surrounding areas and landscape development for larger extents

A consideration of copyright for a national repository of humanities and social science data

In 2011 the Digital Repository of Ireland (DRI) began work on the development of an interactive national Trusted Digital Repository for contemporary and historical social and cultural data. Copyright and intellectual property rights were identified as essential areas which the DRI, as a content holder and data publisher, needed to investigate in order to develop workflows, policy and the Repository infrastructure. We established a Copyright and IP Task Force (CIPT) in January 2013 to capture and identify IP challenges from our stakeholder community and the DRI’s demonstrator collections. This report outlines the legislative context in which the CIPT worked, and how the CIPT addressed copyright challenges through the development of policies and a robust framework of legal documentation for the Repository. We also provide a case study on Orphan Works, detailing the process undertaken by the Clarke Stained Glass Studios Collection, one of DRI’s demonstrator projects, in preparing their content for online publication in the Repository

Enriched biodiversity data as a resource and service

Background: Recent years have seen a surge in projects that produce large volumes of structured, machine-readable biodiversity data. To make these data amenable to processing by generic, open source “data enrichment” workflows, they are increasingly being represented in a variety of standards-compliant interchange formats. Here, we report on an initiative in which software developers and taxonomists came together to address the challenges and highlight the opportunities in the enrichment of such biodiversity data by engaging in intensive, collaborative software development: The Biodiversity Data Enrichment Hackathon. Results: The hackathon brought together 37 participants (including developers and taxonomists, i.e. scientific professionals that gather, identify, name and classify species) from 10 countries: Belgium, Bulgaria, Canada, Finland, Germany, Italy, the Netherlands, New Zealand, the UK, and the US. The participants brought expertise in processing structured data, text mining, development of ontologies, digital identification keys, geographic information systems, niche modeling, natural language processing, provenance annotation, semantic integration, taxonomic name resolution, web service interfaces, workflow tools and visualisation. Most use cases and exemplar data were provided by taxonomists. One goal of the meeting was to facilitate re-use and enhancement of biodiversity knowledge by a broad range of stakeholders, such as taxonomists, systematists, ecologists, niche modelers, informaticians and ontologists. The suggested use cases resulted in nine breakout groups addressing three main themes: i) mobilising heritage biodiversity knowledge; ii) formalising and linking concepts; and iii) addressing interoperability between service platforms. Another goal was to further foster a community of experts in biodiversity informatics and to build human links between research projects and institutions, in response to recent calls to further such integration in this research domain. Conclusions: Beyond deriving prototype solutions for each use case, areas of inadequacy were discussed and are being pursued further. It was striking how many possible applications for biodiversity data there were and how quickly solutions could be put together when the normal constraints to collaboration were broken down for a week. Conversely, mobilising biodiversity knowledge from their silos in heritage literature and natural history collections will continue to require formalisation of the concepts (and the links between them) that define the research domain, as well as increased interoperability between the software platforms that operate on these concepts
