Calisphere and the Online Archive of California (OAC) are gateways to unique collections held by libraries, archives, museums, and other cultural heritage institutions throughout California.

Farewell, Matthew McKinley

Our colleague Matthew McKinley has accepted the role of Full-Stack Developer with Omeka, which provides open-source web publishing platforms for sharing digital collections and creating media-rich online exhibits. He will be working with a team of colleagues primarily centered in Fairfax, VA to support the core Omeka Classic and Omeka-S software, as well a range of modules and plug-ins designed for those systems.

Matthew joined the CDL almost exactly four years ago as the Metadata Harvest Programmer in what was then the Digital Special Collections team (now the Publishing, Archives, and Digitization Group), transitioning from his previous role as a Digital Project Specialist at the UC Irvine Libraries. While at CDL, Matthew significantly advanced our harvesting activities through “Harvesting California’s Bounty” -- a multi-year project supported by the U.S. Institute of Museum and Library Services (IMLS) under the provisions of the Library Services and Technology Act (LSTA), administered in California by the State Librarian -- spurring a growth in the breadth and depth of content available through Calisphere. He has worked with a broad range of cultural heritage organizations throughout California to make their collections more widely available through Calisphere (and subsequently, DPLA). This includes many public libraries, academic libraries, and numerous institutions represented through large-scale collaborations such as California Revealed. Matthew has been instrumental in establishing an operational harvesting workflow, while refining our codebase and extending it to support a broader range of contributors’ systems such as Omeka, Flickr, Islandora, PastPerfect, and YouTube. Matthew’s efforts have helped to dramatically increase the number of publicly available items in Calisphere, reaching the one million mark two years ago and climbing to over 1.8 million as of the end of September this year. We will miss Matthew’s talent and expertise, timely and well-crafted Calisphere social media posts, and good humor and wit — but we’re glad that we’ll be able to continue working with him in other digital library contexts.

Matthew’s last day at CDL is September 30, 2020. While we are sad to see Matthew go, we are excited that he is joining a partner organization and are looking forward to collaborating with him in the future. Please join us in wishing Matthew well on this exciting next step in his career, and thanking him for his contributions to CDL, UC, and cultural heritage organizations throughout the state.

Over 50 New Collections via California Revealed!

We are thrilled to share that Calisphere has added over 14,000 items this summer from 51 libraries, archives, and museums participating in California Revealed, a State Library initiative to help California’s public libraries and local heritage groups digitize, preserve, and provide online access to archival materials (books, newspapers, photographs, audiovisual recordings, and more) that tell the incredible stories of the Golden State.

Some of the newest collections include posters from the Center for the Study of Political Graphics, photographs and reports from the San Diego Zoo Global Library and Archives, and more!

Metadata Analysis Reports on Digital Collections

Recently developed “metadata analysis” functionality can now be applied to any given collection published in Calisphere. The resulting reports indicate the extent and degree of unique metadata values in the collection, which can be used for quality control checking and data cleanup purposes.

A “Metadata Summary” page is available for each specific collection, and is presented as a table:

A brief set of step-by-step instructions are available: Metadata Analysis Reports for Collections, including a video overview that introduces how to access these metadata analysis reports, as well as tips to navigate and interpret these summary reports.

Tips and Reminders!

Calisphere contributors, are you moving your digital collections to a new DAMS?

If you are considering or in-process of migrating your digital collections to a new digital asset management system, or changing the domain name for your digital collections site, please let us know. Some examples of changes include:

  • Migrating to a new DAMS, for example from CONTENTdm to Omeka
  • Updating the domain for your digital collections, such as "" to ""
  • Updating your security certification, for example from "http://" to "https://"

Since Calisphere is based on a metadata harvesting model where we pull in metadata and thumbnails that point to content hosted on your own site or system, send us a heads up if you see a new DAMS in your horizon. We can help ensure that Calisphere continues to point users to your item links, even after your big move.

For more information, see the following article on our OAC/Calisphere Contributor Help Center: Changes to Your Digital Collections System, Domain Name URLs, or Item Page URLs.
