In the Spring of 2022, the BHL Cataloging and Metadata Committee investigated the possibility of harvesting persistent identifiers (PIDs) from Wikidata as part of the group’s longstanding project to disambiguate and deduplicate author records in the BHL database. The motivation behind this one-time experimental data harvest was to see if BHL could:

1. Enhance BHL author records with additional PID data points;
2. Improve the committee’s ability to disambiguate author names in the BHL database; and
3. Respond to an outstanding user request from two of Wikimedia’s super star editors, Siobhan Leachman and Andy Mabbett, to expose BHL’s author data on BHL and include hyperlinks to other authoritative knowledge bases on the web.

In particular, Wikimedians wanted to see the Wikidata Q identifier exposed, providing a link to the corresponding creator item record in Wikidata.

There are multiple motivations for undertaking this work. By adding the BHL Creator ID to the corresponding Wikidata item, Wikidata editors help link BHL to the richer biographical data about that person held in Wikidata. The Wikidata item for a person may contain links to their Wikipedia page or to images of the person held in the image repository Wikimedia Commons. Wikidata items also act as identifier hubs and contain links to other databases and identifiers.

By adding the BHL Creator ID to this list of identifiers, the Wikidata editor is linking the content held in BHL to the content held in multiple other datasets and repositories.

These extra author data points provide Wikimedians and BHL catalogers with crucial clues that aid in name disambiguation. In particular, hyperlinks to other knowledge bases are incredibly valuable because they lead to new knowledge pathways that help confirm a person’s identity in a complex game of “Who’s Who?”

Recently, BHL performed a comprehensive review of all live data feeds and outputs to ensure that we are providing robust metadata to our downstream consumers. Live BHL data can be found at BHL’s Developer and Data Tools. BHL’s live data outputs include:

• API v3
• OAI-PMH

OAI-PMH is an acronym for the Open Archives Initiative Protocol for Metadata Harvesting. It allows other discovery services and aggregators to harvest BHL’s metadata in standard formats such as Metadata Object Description Schema (MODS) and Dublin Core (DC).

To provide more robust data in BHL’s OAI-PMH Dublin Core feed, three changes have been made to the feed:

1. Creative Commons (CC) license information was added as a second <rights> element;
2. A <relation> element was added to titles that are part of a monographic series, allowing BHL to model more complex bibliographic relationships that exist in the BHL database; and
3. A non-standard “type” attribute was removed from the <relation> element for parts.

Important: If you are a developer, using the non-standard “type” attribute in your code at the part-level, this is a breaking change. Please take note and update your code accordingly.

For BHL, 2022 was a year to focus on critical upgrades for the BHL platform to ensure the sustainability of our services for our global users. Although BHL’s basic technical infrastructure remains the same, consisting of years of refinement, knowledge, and reliability, a few updates were definitely in order. Most of these upgrades were “behind-the-scenes” work and would not be noticeable to a majority of our users. However, keeping up with these important enhancements is a crucial component of any technology project.

Last week, the biodiversity informatics community and BHL lost one of its most creative minds. David Remsen lost his lifelong battle with mental illness and passed away on Wednesday, December 14, 2022. As a staff member of the MBLWHOI Library working with BHL’s inaugural Vice-Chair, Cathy Norton, David’s innovative and groundbreaking work in taxonomic name finding (uBio) and parsing taxonomic index (Nomenclature Zoologicus) laid the groundwork for much of BHL’s taxonomic infrastructure powered by the Global Names Architecture.

The BHL Collections Committee has completed a comprehensive review and revision of BHL’s collection development policy. The new policy is written to provide recommendations and serve the collection management needs of BHL Partners. As a key objective of BHL’s Strategic Plan 2020-2025, the new policy is a significant revision to the original policy written in 2010. In learning together as a collaborative community of practice since then, our understanding of BHL collection management has been expanded and refined to:

• clarify collection management priorities;
• articulate our responsibility to pursue more diverse perspectives;
• outline BHL Partner expectations;
• better define our scope;
• describe BHL-specific curation best practices; and
• provide transparency by posting the complete policy via BHL’s About Site.

Going forward, the collection development policy will be reviewed on a yearly basis for minor updates.

The Global Biodiversity Information Facility (GBIF) convened for the 29th Governing Board meeting (GB29) in a hybrid format in early October 2022. This was the first meeting with in-person attendance since the GB26 held in conjunction with the Biodiversity_Next meeting in Leiden (20-25 October 2019).

BHL Program Director Martin R. Kalfatovic attended the meeting in person in his role of BHL Node Manager as well as Alternate Representative for the United States (and Second Vice Chair of the GBIF Budget Committee). BHL Immediate Past Chair, Connie Rinaldo, attended virtually as Acting Head of Delegation, standing in for BHL Chair David Iggulden. Preceding the first day of official meetings was for GBIF committees to meet. During this time, I attended the GBIF Budget Committee meeting. The close of the meeting saw a toast to the outgoing chair, Peter Schalk (Netherlands).

The main meetings were held in the historic Art Nouveau building, the former Waucquez Warehouse, designed by Victor Horta, and now housing the Comics Art Museum. GBIF delegates were joined by large models of Tintin, Smurfs, and others.
