Welcome to the Biodiversity Heritage Library Blog

The planet is at a critical juncture, where urgent action is required to combat climate change, biodiversity loss, and secure a sustainable future for our planet. With the release of the recent BHL Wikimedia white paper entitled Unifying Biodiversity Knowledge to Support Life on a Sustainable Planet, the Biodiversity Heritage Library Secretariat hopes that an expanded data vision for the BHL community presents new opportunities to take bold steps forward into Wikimedia projects and the emergent semantic web. The white paper sheds light on BHL’s crucial role as a member of the biodiversity informatics community and reveals a series of key use cases and big data challenges that, if addressed, could be opportunities to enhance global biodiversity data infrastructure.

Originally scheduled for 2020, the BHL Annual Meeting finally made it to Paris after two years of virtual meetings and a break to hold the 2022 BHL Annual Meeting in conjunction with the Society for the Preservation of Natural History Collections (SPNHC) and the Natural Sciences Collections Society (NatSCA) meetings in Edinburgh, Scotland.

The host for the 2023 meeting was the library of the Muséum national d’Histoire naturelle (MNHN), led by Alice Lemaire, Clément Oury, and Gildas Illien. The meeting took place 17-21 April 2023 and included BHL business meetings, tours of library and museum sites, and a BHL symposium titled “Fostering Data Driven Natural Science through Open Digital Libraries”. In total, the meeting gathered 38 attendees (both in-person and virtually) from 22 BHL partners from around the world.

During 2020, the Archives team at Kew Gardens developed a collaboration with the University of Roehampton, the University of the Third Age (U3A), and the Biodiversity Heritage Library (BHL), to create a model for the archive sector, which uses volunteer-driven, remote methods to transcribe and research collections, making them easily shareable and accessible using TEI-XML encoding. We wanted to create ways in which TEI could be embedded in the archive sector and managed by archivists with little experience of textual encoding, or time to carry out encoding themselves. In creating this model, we would also digitise, transcribe, encode, and make accessible in BHL one of Kew’s most important, but inaccessible volumes – the Kew Record Book. For Kew, it was important that the volume would be made fully accessible, as part of our commitment to transparency around our history and involvement in colonialism.

The model we created was timely, as the COVID-19 pandemic meant many institutions could no longer accommodate volunteers on-site, and remote ways of working have persisted. The Travelling Plants project built a community and model of engaging with and developing the digital capacity of older people remotely, a sector of society that particularly felt the impact of social isolation during the pandemic.

Through ongoing collaborative collection building and digitization, the United States Department of Agriculture’s National Agricultural Library (NAL) is partnering with the Biodiversity Heritage Library to support biodiversity and scientific research in Ukraine with the release of the Ukrainian Українська Collection. BHL and NAL stand with the people of Ukraine and echo the support of its consortium partner institutions in their condemnation of the Russian Federation’s invasion.

The threat to Ukraine’s cultural heritage materials remains substantial during the wartime humanitarian crisis. Many libraries and cultural heritage institutions throughout Ukraine have been severely damaged or destroyed, resulting in the permanent loss of culturally and scientifically significant content. Through the digitization of historic materials related to biodiversity research in Ukraine, this project will help support Ukraine’s scientific community by providing access to these important resources.

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.
