Introductory text to combined scenario summaries

Presented in subsequent articles are illustrative summaries of workflow scenarios in the art & media and space science domains that have been used in the project to help in understanding stakeholders needs and the contextual challenges associated with long-term preservation of data.


PERICLES aims to address the challenges of ensuring that digital content remains accessible, understandable, and usable over time. The project is addressing these challenges by a ‘preservation by design’ approach, in which we mitigate the risk from diverse forms of change by capturing a wide range of significant information about a digital object and its environment.


Working with examples of real environments in which stakeholders deal with digital materials is essential in order to successfully develop the models and tools to both describe the digital objects environment, extract relevant preservation-related metadata from that environment, and monitor and adapt to change within that environment. This project is working with digital content and stakeholders from two quite different domains: on the one hand, digital artworks, such as interactive software-based installations, and other digital media from Tate's collections and archives; on the other hand, scientific and operational data originating from the European Space Agency and International Space Station.


Early case studies within the project discussed broad preservation issues related to digital objects within the context of their user-domains and served as a starting point from which to implement a methodology, grounded in scenario-based design, for both understanding the needs of stakeholders with regards their working practice and also to provide contexts for validating – and nuancing – the models, methods, and tools within which the key themes of the project can be explored in concrete terms.


Initially five scenarios were delineated from the art & media and scientific domain case studies with the intention of serving as user-friendly descriptions of a precise sequence of events that should be implemented. From these descriptions functional and non-functional requirements were extracted to both drive the creation of the research outputs of the project and to evaluate their validity for use within the domain contexts.


It should be noted that these five scenarios formed a basis from which to work. They were developed through numerous interviews with key expert practitioner stakeholders within the project as well as monthly scenario development meetings. Within the context of each scenario there are also a number of sub-scenarios developed that use the same background information but include more specific details on user actions and over the course of the project new scenarios or more detailed sub-scenarios will be created as the projects research needs continue to evolve.


The scenarios primarily sought to contribute to an understanding of:

  • What kind of data is to be preserved and to what level?

  • Who are the relevant stakeholders?

  • What types of access mechanisms or services are required?


The results of assessing the first iterations of these scenarios has now been published in D2.3.1: Media and Science Case Studies_Functional Requirements and User Description, available here http://www.pericles-project.eu/deliverables/9


The scenarios developed within the art & media use case covered a range of different areas within the life cycle of digital objects. The Tate Media scenario looked at creation and re-use. The Digital Video Art scenario focused on ingest and the Software-Based Art scenario looked at a specific preservation action, namely virtualisation. The Born Digital Archive scenario considered appraisal. An example scenario developed within the Science use case focused on knowledge capture and reuse in the context of experiments or operational tasks.


A brief illustrative summary of each of the workflow scenarios is presented below highlighting the preservation-related challenge and how the scenarios will be of use to the project and its research outputs.
