Challenges, Solutions, and Workflows Developed for the Taxonomic Backbone of the World Flora Online.

The World Flora Online (WFO) is the collaborative, international initiative to achieve Target 1 of Global Strategy for Plant Conservation (GSPC): " An online flora all known plants. WFO provides an open-access, web-based compendium world’s plant species, which builds upon existing knowledge and published floras, checklists revisions but will also require collection generation new information on poorly groups unexplored regions (Borsch et al. 2020). construction Taxonomic Backbone central entire as it determines accessibility additional content data at same time, represents a taxonomic opinion circumscription those taxa. List v.1.1 (TPL 2013) was starting point backbone, this most comprehensive resource covering plants available. We have since curated higher taxonomy based following community-derived classifications: Angiosperm Phylogeny Group (APG IV 2016), Pteridophyte (PPG I Bryophytes (Buck 2008), Hornworts & Liverworts (Söderström 2016). presents community-supported consensus classification with aim being authoritative global source world's diversity. backbone actively by our Expert Networks (TEN), consisting specialists groups, ideally Family or Order level. There are currently 37 approved TENs, involving more than 280 specialists, working WFO. small TENs like Begonia Resource Center Meconopsis (with five specialists), medium Ericaceae Zingiberaceae Centers SolanaceaSource.org (around 15 experts), larger Caryophyllales.org Legume Working Group, 80 involved. When we do not oversight, Checklist Vascular Plants (WCVP 2019) has been used update families from TPL 2013 classification. Full credit acknowledgement given original sources key requirement collaborative project, allowing users refer primary data. For example, association kept through local identifiers providers link their own resources. A that every name should globally unique identifier maintained, forever. After considering several options, Technology recommended Council establish Identifier (WFO-ID), 10-digit number “wfo-” prefix, aimed establishing resolvable names, only be in context can universally reference names. Management challenge v1.1 derived multiple datasets, led duplication records. reason, names excluded public portal deleted. WFO-ID deleted nor reused after Backbone. Keeping these allows better matching when assigning WFO-IDs providers. Nevertheless, implies certain considerations duplications. New added via nomenclators International Name Index (IPNI, Royal Botanic Gardens, Kew 2021) Angiosperms, Tropicos (Missouri Botanical Garden Bryophytes, well harvesting endemic infraspecific providing descriptive content. passed TEN make judgement status. provide list group, first produce Matching report ensure no missed. Several issues come managing maintaining lists, process curating ever-growing integrated leads increase challenges face homonyms, non-standard author abbreviations, orthographic variants duplicate Matching. eMonocot database application, provided Kew, (Santarsiero subsequently adapted Missouri underlying functionality WFO's current toolset, proven itself challenging component update.
