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.
