LTDS First Quarter Fiscal Year 2023 

LTDS First Quarter Fiscal Year 2023 (July 1, 2022 – September 30, 2022)


This first quarter of fiscal year 2023 was another productive period for LTDS (Library Technology and Digital Services). The team was able to complete several projects (tasks requiring more than 40 hours of work) and still resolve an impressive number of INFORM tickets.

A few of the projects that LTDS completed during the past quarter are: 

  • Migrated systems using LDAP authentication to the new LDAP authentication servers 
    • This will allow us to continue to access resources using the campus LDAP instance.   
    • The change does not allow VUMC users to access some resources due to information not being available in the system.  
  • Migrated the Digital Commons website to the library website 
    • Allows the Digital Commons resources to be available and the web presence maintained through the library website. 
  • Redeveloped Primo views to utilize the upgraded software provided by Ex Libris 
    • Ex Libris changed the version of the programming language (AngularJS) that is used to present the Primo interface.   
    • Several parts of the Vanderbilt code needed to be adjusted to maintain compatibility with the recent changes. 
  • Upgraded ArchivesSpace 
    • The updated version of ArchivesSpace provides a foundation for new services in the coming years. 
  • Began use of CloudFront distribution 
    • The CloudFront distribution (CDN) provides a central repository for library web assets. This AWS (Amazon Web Services) based system allows for core web elements (branding, menus, styles, etc.) to be changed in one place and reflected across all library sites utilizing the CDN.  
    • The next project is to incorporate the CDN into additional systems. 


LTDS continues to work with other groups in the libraries, on campus, and in the broader library community. Selected partnerships during the first quarter are listed below. 

  • ACE on the web migration project. This project is co-chaired by Jodie Gambill and Kristina Bisbee and will migrate the primary library website from Omni to WordPress. 
  • SCUA and Digital Preservation to develop improved workflows for assuring that digital collections are preserved and discoverable.  
  • VUIT Genesis project to complete migration of library application authentication to the new campus system. These changes allow us to continue to use VUNetIDs for authentication. 
  • PSI and Center for Teaching to implement the improved LTI integration between Leganto and Brightspace. 
  • Digital Strategies to utilize the new campus web templates and deploy the new server.  
  • VUIT Cloud Services team and VUIT Storage team to explore storage options for the growing needs for library digital collections. 
  • VUIT Desktop Engineering continued collaboration to support library staff and circulating laptops. 


LTDS by the numbers:  

  • Number of Proxy Sessions: 145,166 
  • Number of Informs Resolved: 697 
  • Number of servers managed: 35+  
  • Number of items added to Fedora: 484 
  • Number of websites rebranded: 110+ 
  • Number of sites and applications managed: 150+


During the coming months LTDS will continue to work on several projects including: 

  • Creating a set of tools for staff to assist in sharing metadata from digital objects between systems 
  • Adding information about space usage in the libraries to the website. 
  • Adding additional storage capacity to digital collections. 
  • Continued work to migrate resources from older systems to current technologies. 


Domain-based Message Authentication, Reporting, and Conformance (DMARC) is an email process that assists in preventing phishing attempts.    DMARC looks at an email and determines if the information about who is sending the email matches with the sending server information.

in order to fully implement DMARC LTDS has been working with VUIT to change how email from some of our systems are sent.  LTDS has made and implemented changes for Alma, myEMMA, and other systems over the past 6 months.  We believe all issues have been resolved based on current information.

macOS Catalina Released

Apple has released the latest version of the Mac operating system: macOS Catalina (10.15). Currently, there are no plans to push this upgrade out via AirWatch, so staff may choose to manually install if desired. However, a couple of things to keep in mind before you upgrade:

Catalina drops support for 32-Bit apps

We don’t recommend upgrading to macOS Catalina without first confirming that the apps you need are 64-Bit. 32-Bit apps will not work on Catalina.

How can I tell which apps are 32-Bit?

Here’s a quick and easy way to check:

  1. Click the Apple icon on the left side of your menu bar
  2. Select About This Mac
  3. Select System Report…
  4. Under Software (third drop-down), choose Applications
  5. Look under the field 64-Bit (Intel) to see which of your apps are 64-Bit vs 32-Bit; you can click on the field to sort 32-Bit apps first

What do I do if an app I need is 32-Bit?

First, check to see if your app is up-to-date; if not, install the updates. If this doesn’t resolve the issue, then you’ll have to stick with your current version of macOS until you can find a suitable alternative, or the app’s developer updates to 64-Bit.

Upgrading Parallels

Upgrading macOS before installing the latest version of Parallels may prevent your VMs from booting up. If you use Parallels and would like to upgrade macOS, please let LTDS know via INFORM so we can purchase a new Parallels license for you first.



With that said, it’s generally a good idea to wait for a major update (10.15.1) or two (10.15.2) before upgrading to a new macOS. This gives Apple time to identify and resolve many of the initial issues related to a new macOS release. If you have any questions or concerns about updating your Mac to Catalina, please let us know!

AirWatch for Staff Macs

As many of our staff Mac users are aware, LTDS is in the process of deploying AirWatch, a mobile device management (MDM) solution that the University uses to administrate Macs around campus. Moving to AirWatch allows us to remotely manage our Mac computers through a central online console. Through this console, we’re able to:

  • See the current owner of a computer
  • Read information about the model to inform hardware replacements
  • View the OS version to ensure that everyone is using a currently supported macOS
  • Deploy applications
  • Assign profiles to computers that enforce specified policies, like FileVault encryption
  • Lock the device should it ever become lost or stolen
  • Provide an App Catalog in the Dock from which you can install on-demand applications as desired

If you have any questions about or issues with AirWatch, please let us know.

Using Microsoft Planner to organize your projects

A few years ago, many of us in the library discovered Trello and began using it to help our projects stay on track and organized. It’s been a wonderful tool, but unfortunately for us, they recently went to a new pricing setup that prevents the library from using it going forward.

Fortunately, this happened just as the library was starting to move toward using the Office 365 suite of applications provided by the university. One of the applications in the suite is Microsoft Planner, a project planning tool that is very similar to Trello. LTDS is encouraging library staff to make the transition to Planner as you have new projects to track. Several library groups have already started using Planner, including LTDS (unit), ACE (unit), and the Revised Common Lectionary group (project). You might want to use it as a department, a committee/task force, a project group, or any other configuration of people. It’s up to you!

Don’t worry — we’re here to help you get started! Simply submit an Inform to get the process rolling. LTDS must do the initial setup for you at this time, and then you’ll have free reign to set up your tasks (cards) within your plan (board). LTDS is also available to provide a basic overview of the Planner interface.

Public Mac Deep Freeze Upgrade

With macOS High Sierra, Apple introduced a new file system creatively named Apple File System (APFS), replacing the old HFS+ file system (also known as Mac OS Extended) from the 90s. Unfortunately, Deep Freeze at the time was incompatible with APFS-formatted volumes, preventing us from upgrading our public Macs beyond macOS Sierra. For those unfamiliar with Faronics Deep Freeze, it is reboot to restore software; in other words, any changes made to a computer do not persist across reboots, thus protecting the machine and reducing administrative time.

Faronics recently released Deep Freeze Mac version 7 with full APFS compatibility, allowing us to upgrade to the recently released macOS Mojave starting with the Science Library’s public iMacs. LTDS plans to upgrade the remaining public Macs this summer.

What’s New in the Digital Imaging Laboratory

Successful digitization results in a digital image that best depicts the physical item being digitized as accurately as possible. To ensure truthful color reproduction, color values must be matched to a known target.

Library Technology and Digital Services recently acquired X-rite’s ColorChecker, color reference targets, and camera calibration software for use in the Digital Imaging Laboratory. A digital image of the ColorChecker’s reference target is captured by each digital camera in the laboratory. These images are uploaded in ColorChecker’s software to create a DNG file. The DNG file is used to create a color profile. The color profile is then used across the lab’s image editing software to calibrate or recalibrate the color values of images created by the laboratory’s cameras.

The following samples from Le Vingtieme Siecle illustrate a digital image before color calibration and after color calibration.



It is easy to discern the difference in color values. The color values of the bottom image best match the color values of the actual page.The ability to ensure color accuracy is vital to any digitization project.
