Time-Based Media

A recording of the panel discussion “Safeguarding + Activating Digital Video Information in Cultural Institutions” is now available on the ARLIS/NA Learning Portal:

Safeguarding and Activating Digital Video Information in Cultural Institutions

This event was co-organized by NDSR Art and the Metropolitan New York Library Council (METRO).

A Tour of the Whitney Museum’s Conservation Lab

My NDSR position at Small Data Industries began in July 2018 (blog post about our lab to follow!) and on my third day, I met with my ARLIS mentor Farris Wahbeh for our initial NDSR/ARLIS mentor meeting. Farris is head of Research Resources at the Whitney Museum of American Art, a dynamic and progressive position that oversees the museum’s archives, reference, periodicals, documentation, records management, and special collections. In other words, he works to unify all of museum’s resources, from printed artworks to digital records.




After our introduction, Farris led me on a fascinating behind-the-scenes tour of the museum, including the archives, library, conservation labs and the newly-built study center (a space where external researchers can physically interact with art in the collection) — all of which boast beautiful views of the city.




The conservation spaces are particularly innovative and inspiring — the labs meld together in an open floor-plan that fluidly and catalytically promotes trans-departmental conversations and collaboration. In other words, I observed oil paintings from the 1920’s alongside contemporary art and technical-mechanical pieces. In terms of the museum itself, Farris expounded upon the Whitney’s exceptional architecture — each side of its exterior mimics the defining features of the neighborhood below. (There is an impressive — and interactive — article about the museum’s architecture here).




Most significantly, upon entering Conservation, it was by fortuitous coincidence that we stumbled upon Richard Bloes, Senior Technician and Reinhard Bek, New Media Conservator fine-tuning a time-based media piece titled Searcher, 1966 by James L. Seawright — a 6-foot metal framework with plastic and electronic parts that senses and reacts to environmental light. We also explored the media conservation lab (the only room that has a door and lacks the floor-to-ceiling windows!). This is where digital art pieces are processed and archived upon acquisition.




I was truly stunned by the beautiful design of the museum and by the holistic, fluid boundaries — both physical and intellectual — between the labs and departments (what Farris’ amalgamate role directly advocates). Following the tour, Farris and I went to Fig and Olive to chat more about my project, my recent move to Brooklyn and my analogous PhD research. I am very appreciative to Farris for graciously offering to mentor me through my year with NDSR Art and for facilitating my relationship with the local ARLIS network. For our next meeting, Small Data very much looks forward to welcoming him to our lab in Industry City, Brooklyn!

Troubleshooting the Disk Imaging Workflow

Philadelphia Museum of Art

I’m winding down on the 8th month of my NDSR Art Residency at the Philadelphia Museum of Art and I still have not viewed any of the pieces in the time-based media collection. I’ve seen the DVDs in their cases and the external hard drives neatly tucked away in a storage cabinet, but I have not viewed a single work.

You might be wondering why I don’t just pop a DVD into a DVD player and watch it. Sounds simple enough. Well, think of it this way: if we are to treat the artwork stored on this DVD with the same care as we would a Picasso painting, you can’t just yank it out of storage and throw it in a gallery. Because the condition of the piece is unknown when it is first purchased or pulled from long-term storage, it must first be assessed for degradation or damage. Furthermore, not a single piece in the PMA collection has been backed up: that single copy is all we’ve got. Since I’m not a time-based media art conservator and the PMA does not have one currently on staff, watching a one-of-a-kind DVD has not really been an option.

Until now!

After months of research and meetings with many stakeholders across the Museum (conservators, curators, executives, IT, and archivists) and building a framework to preserve the time-based media art collection, I finally have the resources to create backups of the works currently stored on DVDs and external hard drives.

In order to make certain I am fully backing up the artwork, I have chosen to create forensic disk image backups. A forensic disk image captures every bit of the drive, including the software that makes that hardware work and any deleted content that has not been overwritten. Simultaneously, during the disk imaging process vital technical metadata is extracted and made human readable. The reason for using this approach is simple: forensic disk images produce an authentic and complete preservation backup of the object.

For reference, here’s my workstation setup:

Computer: Digital Intelligence Forensic Recovery of Evidence Device (FRED)

External Hard Drives: G-Technology 6TB G-Drive with Thunderbolt 3 and LaCie 6TB d2 Thunderbolt 3 Desktop Drive

Write Blocker: Tableau Ultrabay 4d

Computer OS: Windows 10

Software: Windows Defender Antivirus software; Oracle VM VirtualBox running the BitCurator Environment. In BitCurator, I’m using prepackaged software: Guymager for creating images; Bulk Extractor for pulling technical metadata; BitCurator Reports for making that metadata easier to read; and Bagger for securely transferring the content.

Over the past two weeks, I’ve slowly and carefully been imaging the master and exhibition DVDs of Jennifer Allora and Guillermo Calzadilla’s 2005 video piece Under Discussion. As expected, this undertaking has not been without its fair share of unexpected obstacles that have required troubleshooting. Although troubleshooting is very much a learn-as-you-do activity, I think it could be useful to share a few examples of the issues I encountered and how I eventually solved them. (Disclaimer: If you find any of my solutions lacking or inaccurate, please do not hesitate to contribute your thoughts to the conversation.)

Problem: BitCurator would not recognize a DVD.

Solution: This can happen for a number of reasons. In my case, BitCurator didn’t automatically recognize the DVD and, consequently, I had to do it manually. At the top of the BitCurator window in the Devices dropdown menu, I found the missing device under Optical as “Host E:”. When BitCurator finally recognized the device, a disk icon appeared in the desktop dock.

Problem: Windows 10 would not recognize an attached disk.

Solution: Devices can only be recognized by one operating system at a time. Once BitCurator is running, it will automatically recognize any devices I attach to the computer; therefore, if BitCurator is open the device will not be recognized in the computer’s native Windows 10 environment. Once I closed BitCurator, the device could be recognized by Windows.

Problem: Guymager does not accommodate some special characters (hyphens, umlauts, etc.) in the disk image file names and destination folders. This has become a larger issue for me because I want to use the TMS Object Number in the unique identifier of digital files and these Object Numbers contain hyphens. When I use a special character that Guymager won’t recognize, an error message informs me it will automatically remove that problem character (i.e. 2006-84-1e becomes 2006841e).

Solution: My solution thus far has been to manually add the hyphens into the file names after the files have been created by Guymager. To make sure the file names match the metadata in the .info file, I have to open the .info file in text software like LibreOffice (included in BitCurator), alter the file names to include the hyphens, and then resave. As this adds a number of steps to the workflow, this is not an ideal long-term solution. Next steps are to explore other imaging software options and/or reassess our unique identifier standards.

Problem: Scanning an external device for viruses without putting the computer at risk of infection.

Solution: Turn off all “Autoplay” and “Auto Mount” settings in Windows 10 and BitCurator and then manually select the drive for virus scanning.

Problem: The newest version of BitCurator VM, 1.8.16, will not fully boot up and gets stuck at an Ubuntu login terminal screen. Additionally, after installation of the new version, the older 1.7.40 version of BitCurator that was still installed in the VM also stopped fully booting.

Solution: This issue is still not fully resolved, unfortunately. After reading through the BitCurator Google Group threads and a number of Ubuntu forums, it would appear the issue derives from the version of Ubuntu in the 1.8.16 BitCurator package. (Please correct me if I am wrong about this!). As it is not recommended to update the programs packaged in BitCurator, these Ubuntu bugs will not be fixed until the next version of BitCurator is released. In the meantime, I have removed the 1.8.16 version completely from the FRED computer. The most thorough way I have found to do this is, from the VirtualBox home screen, right click on version 1.8.16 and select Remove. I was then asked if I wanted to remove BitCurator from VirtualBox or if I wanted to remove the files from the computer. I selected the remove-all-files option. I removed the older version 1.7.40 in the same way and then reinstalled it. The older version is working again.

Problem: Cannot update software on the FRED because it is not connected to the Internet. Consequently, important virus software definitions are always out-of-date.

Solution: On a computer that was connected to the Internet, I found the most recent update of, for example, the Microsoft Defender Antivirus software and downloaded it to that computer. I copied the downloaded file to an external hard drive which I then plugged into FRED. I ran through the installation steps and found that the software was automatically updated. I then deleted the downloaded file off the FRED as it was no longer needed.

NOTE 1: Keeping a log of the updates and setting updates standards/schedules will help with making the updating process consistent and accurate.

NOTE 2: Before adding any new files to the FRED computer, a quick virus check of the external hard drive should be performed in order to verify that it has not been infected by newly downloaded content.

The last example is just one of many issues I’ve stumbled upon related to working on a non-networked computer. I had not anticipated how difficult it would be to manage a computer like the FRED! I’ll never again take for granted all of the automated updating my computer does, because manually managing an non-networked computer is no small task.

If you have any digital forensics troubleshooting experiences, please share them!

An Introduction: “I can’t believe this is my life.”

After nearly 11 years living in Chicago and finally finding a winter coat that actually kept me warm, it was quite surreal to get picked for the National Digital Stewardship Residency in Art. Within roughly 60 days, I managed to completely change my life and I packed up my four cats, one dog, and one boyfriend (now fiancé!), and moved across country. Now that I’m settled in Philadelphia and I have official business cards—hard proof that I am, in fact, not dreaming—the surreal feeling has been replaced with a general sense of “I can’t believe this is my life but start believing it because you’ve got work to do.”

Here are a few of the “I can’t believe this is my life” moments from the first 2 months of this residency:

  1. Immersion Week. Five eight-hour days of digital preservation-related presentations from truly remarkable leaders in this field, including: Sheila Rabun, Community and Communications Officer, IIIF; Jacob Nadal, Director of Preservation at the Library of Congress; Anne Young, Manager of Rights and Reproductions, Indianapolis Museum of Art; George Blood, George Blood LP; Emily Rafferty, Head Librarian and Archivist, Baltimore Museum of Art; Sumitra Duncan, Head of Web Archiving Program, Frick Art Reference Library; Dragan Espenschied, Preservation Director, Rhizome; Virginia Rutledge, PIPE Arts Group.
  2. Getting our official resident portraits taken on the great staircase at the Philadelphia Museum of Art.
  3. Every time I’ve been introduced as the “NDSR Art Resident working with the time-based media collection.”
  4. Seeing the time-based media collection in person for the first time.
  5. Touring the Museum’s offsite storage facilities.
  6. Meeting the Librarian of Congress, Carla Hayden (OMG).

Let me backtrack a bit and explain why this project exists and why I’ve subsequently changed my entire life for it.

The time-based media (TBM) collection is the fastest growing collection at The Philadelphia Museum of Art. With this fact in hand, I almost need not say more. It advocates for itself. It is why this project exists and why I’ve been selected to dedicate my time to nothing else for 12 months.

At present, there are just under 100 time-based media (TBM) artworks in the Museum’s permanent collection, and a number of TBM acquisitions are already on the horizon. However, there is no infrastructure in place to properly handle, preserve, or manage TBMs. To date, these complex artworks have been acquired using existing museum policies and practices, which are insufficient to meet their documentation and preservation needs.

In the Summer of 2017, the Museum hired Mona Jimenez and Martha Singer as outside consultants, two experts in the field of TBM preservation. Together, they performed an eight-day assessment of the TBM collection and compiled their findings and recommendations in a comprehensive report. On my first day, I was handed this report and it has since become the jumping-off point for all of my work.

In 2 months I have: collected and read hundreds of resources; caught up on the status of existing institutional knowledge of the TBM collection; interviewed numerous stakeholders; and applied to present at two conferences (so far) and made arrangements to attend four. I have played with a FRED machine, explored Preservica, and become the go-to person in my office for questions about The Museum System (TMS). I recently performed a visual inspection of the collection’s 16mm films, begun the process of sifting through the collection’s Object Files, and collaborated with the Contemporary and Conservation Departments on writing an executive summary of the assessment to present to  the Museum’s Executive stakeholders. I’ve attended the Museum’s Contemporary Conservation Working Group meetings, plan to attend the ARLIS Mid-Atlantic meeting later this month, and will be visiting the Minneapolis Institute of Art in Minnesota for a Host Enrichment Session to learn about Mia and their NDSR Art project.

Obviously, there’s a lot to be done, and I couldn’t be happier about it.
