Long-term Preservation Storage: OCLC Digital Archive versus Amazon S3

Last month OCLC announced a new service offering for long-term storage of libraries’ digital collections. Called Digital Archive™, it provides “a secure storage environment for you to easily manage and monitor the health of your master files and digital originals.” Barbara Quint has an article in Information Today called “OCLC Introduces High-Priced Digital Archive Service” in which she makes a comparison to Amazon’s Simple Storage Service (or “S3″) from primarily a cost perspective: “The price for S3 storage at Amazon Web Services is 15 cents a gigabyte a month or $1.80 a year, in comparison to OCLC’s $7.50 a gig.” Barbara also goes into some of the technical differences, but I think it might be worthwhile to go a little more into depth on them.

Getting a Hyperlink of the Last Sent Message from Mail.app using Applescript

I’ve been a fan of Getting Things Done as a technique for managing projects, but it was only recently that I settled on OmniFocus as the “trusted system” collecting all of my next actions. One of the things I like about OmniFocus — as a rich, Mac-only application — is its ability to hold links to messages from Mail.app as notes for each action. This occurs, for instance, when you use the “Clippings” function of OmniFocus to create a new action based on the message that you are currently viewing in Mail.app. (There are other ways to do it, such as the method described by Adam Sneller.)

One of the things I find myself doing is creating actions in a “Waiting” context based on e-mail messages I’ve just sent. Initially, I’d just create the action via the OmniFocus Quick Entry window. But I found myself needing to refer back to the message I sent when the person I’m waiting on doesn’t come through. So I started clicking and dragging the message from the Sent mailbox to the action. But to do that I’d have to click into the Sent mailbox and have the Mail.app and the OmniFocus windows set up just right. Or I’d have to follow a select-sent-mailbox, select-message, OmniFocus-quick-entry-with-clipping, select-Inbox, select-next-message workflow. And that took time and effort. So I’ve created an AppleScript ditty that does the work of creating a hyperlink on the clipboard of the last sent message. The results can then be pasted into any RTF-aware application, including OmniFocus.

Thumbgrabber: a metadata augmentation tool

Blogging on Peer Review ResearchIn reading a background paper for the American Social History Online portal, I was reacquainted with a paper by Muriel Foulonneau, Thomas Habing and Tim Cole from UIUC called “Automated Capture of Thumbnails and Thumbshots for Use by Metadata Aggregation Services.”1 This is the abstract:

The practice of including thumbnails in short record displays, increasingly common in local implementations, is being adopted by metadata aggregation service providers as well. In addition, thumbnails and Web thumbshots have begun appearing as part of Web search results. This article reports on a project at the University of Illinois at Urbana-Champaign (UIUC) to make more comprehensible heterogeneous resources available on the UIUC CIC metadata portal by incorporating thumbnails and thumbshots of image and Webpage resources in the context of the OAI Protocol for Metadata Harvesting. In addition to thumbnails provided by partner data providers, UIUC has developed an automated process to generate thumbnails and thumbshots from the Webpages resources pointed to by the metadata records.

Preserving Digital Video

My place of work is looking to acquire educational videos in a digital form with an eye towards long-term preservation. At this point we receive a physical form (preferably DVD, but sometimes VHS) and digitize it to a very lossy access format (RealMedia, in this case). With this change, we would get a preservation-worthy digital copy from the producer/distributor and forego the physical version.

There is quite a lot written on preserving video, but I wanted to distill the requirements down into statements that vendors could reasonably provide today. I think these are pretty sound requirements, but I’m looking for feedback. In particular, I’m not quite sure how to handle the transfer of closed caption text from the publisher/distributor; suggestions are welcome.

LC’s Adoption of Silverlight — Good Deal for Microsoft, Bad Deal for the Rest of Us

Earlier this year, Microsoft announced that it was giving $3 million in “funding, software, technological expertise, training and support services” to the Library of Congress to build on-site and online exhibits of LC historical collections. Others have commented on this. From a Jester’s point of view, I’ve got problems with this on two fronts: Microsoft using LC in a cheap marketing ploy and LC’s use of a new technology that impedes access for no good technical reason.

A Glimpse into the Internet Archive’s Scanning and Print-on-Demand Operations

Wired magazine published a brief story and online photo gallery of the book scanning and print-on-demand projects at the Internet Archive. It is a fascinating glimpse into their vision and processes. Included below are cropped thumbnails and part of the text captions that accompanied the pictures in the Wired online gallery.

The book to be scanned sits in front of a technician underneath a V-shaped glass platter. Two opposing cameras angled at each page take photos of the book. On screen is the multipage view that the operator uses to verify the quality of the scans and the book’s pagination.

Vint Cerf on the Origins of 32-bit IP Addressing

Via a weekly wrap-up post by Dion Almaer on the Google Code Blog comes mention of a Google Tech Talk video from their IPv6 Conference 2008. It is a panel discussion called “What will the IPv6 Internet look like?” and it offers insight into the difficulties of transitioning to the next generation IP transport protocol. Although it has been years since I’ve seen the business end of managing an actual IP network, I found the discussion a fascinating look at the issues that are ahead of network engineers and device manufacturers around the world.

Microsoft Giving Away Developer Software to Students

Stu Hicks, one of OhioLINK’s systems engineers, told the OhioLINK staff last night about a new program at Microsoft called DreamSpark. Through this program, post-secondary students around the world who are attending accredited schools or universities can download some of Microsoft’s big developer and designer tools free of charge. At the time and place this post is being written, the list of software is:

  • Visual Studio 2008 Professional Edition
  • Windows Server 2003 Standard Edition
  • SQL Server 2005 Developers Edition
  • Expression Studio
  • XNA Game Studio
  • Visual Studio 2005 Professional Edition
  • Visual C# 2005 Express Edition

Would the Real “Dublin Core” Please Stand Up?

I’ve been following the discussion by Stu Weibel on his blog about the relationship between Resource Description Framework (RDF) and Dublin Core Abstract Model (DCAM), and I think I’m as confused as ever. It comes as a two part posting with comments by Andy Powell Pete Johnston (apologies, Pete), Mikael Nilsson, Jonathan Rochkind, and Ed Summers. Jonathan’s and Ed’s comments describe the same knowledge black hole that I’ve been facing as well; in Ed’s words: “The vocabulary I get–the DCAM is a tougher nut for me to crack.”

Is JPEG Good Enough for Archival Masters?

On the ImageLib mailing list, Rob Lancefield (Manager of Museum Information Services for Wesleyan University) posted a link to the Universal Photographic Digital Imaging Guidelines (UPDIG) for image creators. The introduction says: “These 12 guidelines — provided as a Quick Guide plus an in-depth Complete Guide — aim to clarify the issues affecting accurate reproduction and management of digital image files. Although they largely reflect a photographer’s perspective, anyone working with digital images should find them useful…. This document, prepared by the UPDIG working group, represents the industry consensus as of September 2007.” The listed members of UPDIG leads one to believe that this is a professional photography group. One thing in the introduction to the guidelines caught my eye, though:

The chapter on archiving now has a discussion of JPEG as an archival format.
