TIFF compression? Use discretion! | Open Preservation Foundation

The British Library’s Digital Preservation Team is sometimes asked to help resolve the preservation planning challenges of Library colleagues and other organisations. This post describes a recent request for assistance, the steps taken to learn more, the conclusions reached, and where this leads us next.

BIBFRAME AV Assessment: Technical, Structural, and Preservation Metadata | AV Preserve

This report presents the findings of a study conducted by Bertram Lyons and Kara Van Malssen of AVPreserve, on behalf of the Library of Congress, to evaluate the existing state of technical, structural, and preservation metadata for audiovisual resources in the bibliographic environment in light of existing standards for audiovisual metadata, and to make recommendations about how BIBFRAME can support the expression of such information.

Bibliographic Framework (BIBFRAME) in Action | Library of Congress

The BIBFRAME Pilot is underway and is a component of a major effort by the Library of Congress to lead the library community into the linked open data world. Developing BIBFRAME requires involvement of information specialists to create a new ecosystem in which bibliographic data are compatible with the broader World Wide Web environment. Speakers will discuss progress to date, relevance of BIBFRAME in today’s environment, and the current status of the BIBFRAME Editor, including a demonstration of the modifications to the Editor from a programmer’s perspective.

McCoy on the future of PDF | Mad File Format Science

Bill McCoy’s article, “Takeaways on the Future of Documents: Report from the 2015 PDF Technical Conference,” offers some interesting thoughts on the future of PDF. I can’t find much to disagree with. PDF is in practice a format for reproducing a specific document appearance, and that’s becoming less important as the variety of computing devices increases. He makes a point I hadn’t thought of, that the “de facto interoperable PDF format” is well behind the latest specifications, which may explain why I haven’t seen complaints that JHOVE doesn’t know about ISO 32000 PDF!

Free OAIS online course - A Beginner's Guide to the OAIS

We’re starting to move the Digital Preservation Training Programme into the realms of the online. As a first step, we’re releasing a free OAIS online course aimed to help with the understanding of the OAIS Reference Model.

The content for this short course comes out of what we currently teach on the Beginner version of the DPTP face-to-face Course. Our plan is to move away from teaching OAIS in the classroom, and move towards students learning it online before they attend the teaching.

An invitation to review and reform OAIS

An invitation to review and reform the OAIS model from William Kilbride of the Digital Preservation Coalition:

Dear All,

It is my pleasure to invite you to participate in a new initiative that will hold our interest for a couple of years and which we aim to build into a platform for collaboration in the digital preservation community in the future.

Out of cite, out of mind: the current state of practice, policy, and technology for the citation of data | Australian Policy Online

The growth in the capacity of the research community to collect and distribute data presents huge opportunities. It is already transforming old methods of scientific research and permitting the creation of new ones. However, the exploitation of these opportunities depends upon more than computing power, storage, and network connectivity.

JPEG2000 & Digitisation: Expert Round Table | TownsWeb Archiving

With digital preservation, and in particular the preservation of digital assets created by digitisation, very much a hot topic in the archives and libraries communities recently; we are being asked more and more frequently by clients which is the “best” image format to use.

Of course the answer is almost always “It depends on your project’s goals.”
