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.

LTDS Last week (July 23-28)

 

Alma, PrimoVE, and the web refresh went live  Monday and Tuesday!  Although these activities we the highlight of the week,  the team also worked on several additional items including the issues below.

  1. Circulation transactions in Alma are duplicated
    1. Caused by some transactions not loading correctly during the final switch over.  Ex Libris is working on the solution.  We expect this to be resolved within a week
  2. Duplicate charges appearing in user accounts
    1. This is the same issue as #1 and should be resolved within a week
  3. Missing holding and item records
    1. Some of the items and data (<0.3%) did not migrated correctly.  Many of these can be corrected in an automate method but the fix needs to wait until the circulation transaction issue is resolved (#1).
  4. Web site access strangeness
    1. The majority of these issues were caused by the DNS changes and were corrected within 24 hours as the various DNS servers were updated.  At least one issue was caused by the storage issues across campus (see #6) but has been resolved.
  5. Unable to connect to Acorn/Workflows to verify information
    1. This is a side effect of the storage issues on Wednesday.  It appears that the indexes were corrupted which we are working to resolve now (thanks Jamen).
  6. Non-responsiveness of the Lectionary, ETD, DiscoverArchive, Digital Collections news online, public website (indirectly),  and other applications
    1. Caused by a campus storage issue on Wednesday and has been resolved.
  7. Some public computers (virtual computers) not responding or unable to login
    1. Caused by the storage issue (#6) and should all be respond now.
  8. TVNews Standard Definition SnapStream server in the Baker server room
    1. The issue originated with a blown transform across from Baker.  Once the power was restored, the UPS in the server room did not respond.  This is the only remaining server in Baker and is in Baker due to the cable connections.  The system is now running but we are working on a permanent solution.
  9. A few printers with scan to email functionality stopped sending email.
    1. A side effect of the web refresh, web server migration.  Most (all??) of these issues have been corrected.
  10. Various Alma items
    1. The implementation team is working to update the configuration in various areas of the system.   Many of these changes had been in pre-production but added after June 27th.  As a result, the change need to be made again in the system (many thanks to Jake, Michael, Mary Ellen, Tao, Nancy, and Jamen for quickly starting the edits).

Technical Freeze Starts This Weekend – So What Can I Do??

What is going to happen this weekend? What will I be able to do? What can be done during the Technical Services freeze? These are all valid and reasonable questions, which I will try to address in this post. No fear, though – you will still be able to work!

Starting this weekend (June 22/23), as soon as Mary Ellen completes the fiscal year roll over (after which she will notify myself), I will launch several scripts on the Acorn server in order to do the full extract of our Symphony data. This is a server-load intensive process and requires several hours of work, during which time Workflows/Acorn will be impacted. You may see slowness. You may have difficulty logging into Workflows. Acorn (web catalog) may be down. DiscoverLibrary will only be impacted if it has trouble picking up the Real-Time Availability information from Symphony, but searching should be fine. My Account feature may also be impacted. But please be patient. We have to do this because Ex Libris needs the data no later than Wednesday, June 27; but our goal is to get the extract done by Monday, June 25, so we can review the data for any errors.

In addition to Acorn, we also need to provide Ex Libris a full extract of our SFX and Verde data. Those processes do not take too long to complete and since they are on separate servers, will not have a huge impact on library services.

But Symphony is a different beast. You may wonder why it takes so long. This is because not only are we extracting all of the data (which, by the way, are millions of records), but we also have to modify some of the data in order to meet Ex Libris’s data requirements (specifically, the Invoices and Orders). This is where it gets tricky, which is why we want a day or two in order to review the data to make sure it is as accurate as we can get it before sending it off. We know from experience that we cannot always depend on the scripts to run correctly all of the time, so we need to be able to re-run the scripts if it obvious there was a problem.

During this time, we specifically request that no large reports be ran because that will slow the process down even further. If it is apparent that a report is running and it taking longer than normal, I will kill the report which means you will need to re-run it once the extract completes. We want to get this done as quickly and as efficiently as possible. In order to do that, we need to minimize the number of processes running on the server, which includes reports.

Once the extract is complete, everything should return to normal. However, if you modify a bibliographic record, add an item record, pay an invoice or any other Technical Services activity after the extract completes, that data will be LOST because we will not be doing another extract of our entire system. On July 18, there will be a Circulation Freeze after which we will need to use Alma’s Offline Circulation Utility for circulation transactions. This means all functions within Symphony should be discontinued. At this time, I will extract patrons, loans, and holds from Symphony and send to Ex Libris. And on July 20, we go live with Alma.

Between June 22 and July 20, you can still use Symphony for running reports, as long as they are read-only reports (not writing). This would be a good time for any statistical data you need to gather. You could also be looking for problems that are currently in Symphony (problem records, diacritics, etc.) and make note of these so that at Go Live, you have a list of items you can check to see if they are any better. You can also compare with our Alma instance at that time to see how the data looks. Alma will be available during most of this time until Ex Libris copies over the data, so you can continue testing and training and honing your skills. This would also be a good time to go through the various training modules available from Ex Libris (https://knowledge.exlibrisgroup.com/), especially if you are unclear on how to do something, so there is plenty of work to be done.

We are trying to make this as painless as possible, but take a deep breath. Learn. Live. Laugh – and have fun. We are all in this together!

Zip File Importer for Islandora Now Available

Step by step instructions are now available for ingesting ZIP files into Vanderbilt’s Digital Collections, the central access point for the Vanderbilt Libraries’ digitized special collections.  Instructions can be found here. https://ltds.library.vanderbilt.edu/library-staff-pages/islandora-ingest/ You must be logged in to access the link.

Additional updates and changes are in store for Digital Collections in the coming weeks and months. Stay tuned!

Audio-Visual Resources in the Community Room

Video recording and streaming is now available in the Community Room for your meeting or event.

The podium is height-adjustable with a lamp, microphone, computer with USB monitor, and HDMI and VGA video connections for use with laptops. Adapters are available for VGA to Mac video and HDMI to USB-C. A connection can also be made wirelessly using AirStream. Wireless laser pointers/clickers are available by request.

Also on the podium is a touchscreen control for the projector, video camera, audio levels, light settings, and retractable video screen and window shades. A duplicate touchscreen control is located in the AV closet at the back of the room.

Besides the podium microphone, the Community Room has three wireless handheld microphones and two wireless lapel microphones available, along with a floor stand and three table stands. Up to four wireless microphones can be used at one time.

Bring an Idea to Life with 3D Printing

Even though the Medical Library is closed for renovations, 3D printing is still available. Want to have something printed? Here is what you do:

Email a link from a 3D printing file repository — Thingiverse, YouMagine, NIH 3D Print Exchange, etc. — or attach your file (.STL or .OBJ extensions only) to ebl3dprint@vanderbilt.edu.

Want to try creating something yourself? Tinkercadan easy-to-use online 3D CAD design tool, is a good place to start.

We will take a look at the request and consult with you about printability, size, resolution, color, and timeframe. Then when it is ready to be picked up, we will send you an email.

Currently, there is no charge for smaller print jobs.

Virtual Desktop Infrastructure (VDI) in the Libraries

Virtual Desktop Infrastructure (VDI) in the Libraries

 

  • What is VDI?

VDI utilizes a desktop computer to run software located on a remote server.  This is the emerging campus standard, it is being implemented as the libraries move to VUIT desktop support for our public computers.

  • Why is the University adopting VDIs?

The goal of the VDI program is to reduce the overall costs of desktops across the University.  As the Library has continued to increase support for digital initiatives, library staff available for desktop support has decreased.  Utilizing the service offered by VUIT allows the public machines to be replaced and maintained on a regular cycle.

  • What are the advantages of using the virtual desktops?

Since the software runs on a server, additional software can be added more quickly.  Changes to the software configuration can also occur more quickly since staff do not need to touch each individual computer.  Some campus libraries require specialized applications on their public workstations, the virtual server environment supports that.  Lastly,  the virtual desktop uses approximately 10% of the power that a physical desktop uses.

  • Will this service be expanded to other staff workstations?

At this time, there are no plans for VUIT to support staff or service desk computers.  VUIT will also not support laptops that are circulated.

  • Why does it take so long to log into the desktop?

The first time a user logs into a machine the must create a new profile.  This will only occur once for a user in each library location.   Initial logins can take as long as 4 minutes.  Subsequent logins in the same library will be much quicker, often under 30 seconds.  If a user goes to a different campus library with a different virtual machine configuration, they will again experience the initial 4-minute profile building login.  Within one library this should be a one-time event.

  • What other initial setup issues will patrons see?
    The first time a user opens an application on a virtual desktop they will see some setup and installation messages for that application. On the very first login, they can expect to see a Pharos installation message.  Once that is accomplished, all printers in that library should be available from within any application, as they were before.

 

  • Does the user have the ability to customize their ‘virtual desktop’?

The virtual machines will work similar to the deep-frozen machines.  Any data saved will be removed when the user logs off.  Users should save their information to a network drive or a USB drive.

 

  • Will the workstation timeout?

Yes, the workstation will timeout after 15 minutes of no activity.

 

  • Should the VDI workstations be turned off at night?

No,  the workstations can remain on.

 

  • Who do I contact if changes are needed?

Please submit an INFORM as you would in the past.

 

  • Who do I contact if a problem is encountered?

Please submit an INFORM.  However, you should also report directly to VMDP.  When reporting to either LTDS or VMDP please include the full ID number which is listed just under Vanderbilt Information Technology (CLN-BQNH5J2 in the example below) on the label in the front of the machine.

 

  • What about the older Mac workstations?

Currently, only the PCs will be replaced.  The discussion to replace the Macs is ongoing but will not move forward until after the PCs are replaced.

 

  • The CD-ROM stations have not been replaced, will they be upgraded?

The CD-ROM workstations are not in scope for this project.  LTDS is currently planning on replacing these machines.

 

  • Who do I send comments to about the new system?

Send comments to ltds-comments@list.vanderbilt.edu
