Dear Community,My name is Martyn Simpson, and I am the new Head of Information Security at Preservica. I am delighted to be part an amazing organization, ensuring that the information you entrust to our platform remains secure. Myself, and the Information Security Team have been working hard on our Information Security Governance, Risk Management, Compliance, Security Operations and ensuring transparency to our clients of the security controls we have in place.We understandably receive a lot of questions from you, our customers as to how Preservica is taking appropriate action for the protection and confidentiality of client data as a cloud service provider. In this newly released paper ‘PRESERVICA SHARED RESPONSIBILITY MODEL’ we’ve detailed the responsibilities that are applicable across our whole service offering but are specifically written in the context of Preservica Cloud. Shared Responsibility Model Please do also check out the rest of our newly launched Trust Center for all th
A paper by Jack O’Sullivan, Jon Tilbury and Richard Smith published at iPRES 2021.Abstract - Digital information often relies on the interactions of multiple individual digital files, rather than being completely encapsulated in a single file. Where this happens, all necessary files should be considered to be part of the same Multi-Part digital object. This paper describes a data model for describing the format of such digital objects, or more specifically, the Multi-Part Representations of such objects. As with the identification of file formats, having a Representation Format like this enables us to determine which tools to use to undertake particular preservation actions for a Representation.Keywords - Format identification, data model, complex objects For more information go to https://files.sciconf.cn/upload/file/20211206/20211206163241_26411.pdf
A paper by Matthew Addis, Justin Simpson, Jon Tilbury, Jack O’Sullivan, Paul Stokes published at iPRES 2018.Abstract - Current digital preservation systems such as Archivematica and Preservica lack a common and consistent way to describe and execute preservation policies and actions at a technical level. Archivematica’s Format Policy Register (FPR) and Preservica’s Linked Data Registry (LDR) both define what tools and rules to use when doing digital preservation and whilst these two approaches aim to solve similar problems, they are not interoperable. There is no way to share technical information between the two solutions and for users to share their experience on what approaches to use in different contexts and why. This hinders implementation and execution of digital preservation in an interoperable way within the digital preservation community. This paper presents new work by Artefactual, Arkivum, Preservica and Jisc on how Preservation Action Registries (PAR) could be used to capt
A paper by Jack O'Sullivan and Jon Tilbury.Abstract - since the 1960s, digital preservation has transformed from a secondary activity at a select few cultural heritage organizations to a vital international effort with its own best practices, standards, and community. This keynote presentation and paper presents an overview of the changing scope of digital preservation, issues, and strategies for digital preservation in the cultural heritage community.Keywords - digital preservation, knowledge sharing, PAR For more information go to https://www.ingentaconnect.com/content/ist/ac/2020/00002020/00000001/art00003#.
A paper by Rory Blevins, Ismail Patel, Jack O'Sullivan, Ashley Hunter, Robert Sharpe,Pauline Sinclair published at iPRES 2013.Abstract - This paper describes a mechanism for improving the scalability of preservation actions on large linked archives, such as WARC and ARC files produced from the archiving of web sites. To enable accurate but efficient preservation actions, information on the files embedded within a container object, such as the file formats of the embedded files, are aggregated and recorded as properties of the container object. This occurs during the ingest of objects into the archiving system, specifically at the characterization stage when files are identified and validated. To ensure that the details of all embedded files are also recorded, nested archives are recursively unpacked and their contents characterized to identify all files in a package. Information about the embedded files is then stored as properties of the container object: this allows us to efficiently
A paper by Jonathan Tilbury, Remke Verdegem and Euan Cochrane published at iPRES 2019.Abstract – Digital Preservation places a strong emphasis on building communities to share experiences and develop solutions. Traditionally these communities were built on geographic or functional alignment or created through external grant funded research activities. As commercial Digital Preservation products have emerged vendors have created User Groups for their customers that seek to fulfil this function. Using the lessons of the 11-year history of the Preservica User Group, this paper explores how these User Groups function and compares this to studies of User Groups in other domains.Keywords – Community; COTS; User Group;Conference Topics – Collaboration: a Necessity, an Opportunity or a Luxury; Building Capacity, Capability and Community For more information go to https://osf.io/6tyba/.
A paper by Jack O'Sullivan Richard Smith Alan Gairey Kevin O'Farrell published at iPRES 2019.Abstract – a data model is an expression of how a system is intended to be used, and a statement of how it should interact with other systems. As part of the development of the latest version of Preservica, the underlying data model was significantly altered, informed by what went before and by reference to the experiences and best practices distilled into the PREMIS Data Dictionary. This paper reports on some of the key decisions made in the application of the PREMIS concepts to an extant digital preservation system.Keywords – PREMIS, Data Model, Digital Preservation SystemsConference Topics – The Cutting Edge: Technical Infrastructure and Implementation; Designing and Delivering Sustainable Digital Preservation.

A paper by Jack O’Sullivan and Jonathan Tilbury.Abstract - Using a case study of how Preservica software was used within the Preservation Action Registries initiative, this paper explores how the exchange of file format best practice across the whole digital preservation community, including between suppliers of competing systems, is leading to improved automation. The primary focus of this work is on enabling users without deep technical knowledge to avail themselves of these technologies, so they can focus on the organisation, curation and presentation of their collections. The paper also explores some of the unanswered questions regarding how this automation can be achieved and what part users who do have deep technical knowledge will play in this future.Keywords - PAR, migration, digital preservation, automation, registry, policy For more information go to https://www.henrystewartpublications.com/jdmm/v9.
