abstract = {Virtual aggregators of organism names and taxa play a normative role in consolidating the global biodiversity information infrastructure, serving as resources for researchers worldwide. These aggregators may serve as the glue that binds together local data, ranging from individual researchers' spreadsheets to large databases containing taxonomic checklists for countries or entire regions of the world. The European Union-funded TETTRIs project (Transforming European Taxonomy through Training, Research and Innovations) targets both local data holders and aggregators, aiming to motivate and enable local users to verify their data with the aggregators and, optionally, to link to the aggregators’ services (Berendsohn 2023). It also aims to foster the development of aggregator-side services that streamline usage and facilitate the establishment of such linkages.Here we focus specifically on botanical collection databases, i.e., the plant names contained in herbarium databases. By matching these names to botanical data aggregators like the World Flora Online (WFO) Plant List or the World Checklist of Vascular Plants (WCVP), curators can identify and correct obvious errors in their records. Where an exact match is obtained, the curators can check the aggregator’s opinion about the nomenclatural validity, the taxonomic acceptance and the classification of their name, which may help e.g., in the processing of loan requests. Additionally, by reporting missing or incorrect names or commonly used orthographic variants, curators contribute to improving the overall quality of the infrastructure.There are several services that may be used for name matching. We strongly suggest using the service offered by the WFO Plant List, because the dataset is becoming the most comprehensive global resource for the names of plants (excluding algae). It is inclusive, i.e., it tries to cover all names and name-like designations that have been used in published taxonomic sources. It provides unique, resolvable and stable WFO name identifiers (Miller et al. 2023), and assigns new ones for names that have been corrected. It is supported by a broad spectrum of international botanical institutions (52, up to now). It closely cooperates with existing nomenclators such as Kew’s WCVP, Missouri Botanical Garden’s TROPICOS, and the International Plant Names Index (IPNI). Large parts are edited by TENs (Taxonomic Expert Networks, see Borsch et al. 2020) that may respond to input from users. It provides a unique, stable, resolvable WFO name identifier that can be integrated into local databases and used to follow up on changes made on the aggregator’s side. The data is published under a CC0 rights waiver and the ID connects it to the World Flora Online content website. We looked at specimen occurrence data supplied by herbaria to the Global Biodiversity Information Facility (GBIF). GBIF facilitated a dataset (GBIF.ORG 2024) with a count of specimens for all distinct scientific names in the supplied data for Plantae, plus the name they had matched it to in the GBIF backbone (a pragmatic assemblage of name and taxa from multiple botanical data sources). We filtered out algal groups by selecting only names from Anthocerotophyta, Bryophyta, Marchantiophyta, and Tracheophyta. With the 110,089,964 specimen records came 2,922,635 distinct names. GBIF is taking a number of measures to match names, so that in the end most of the specimens can be assigned to a taxon name in the GBIF backbone. However, we focused on exact literal matches of names, including author abbreviations. Only 681.211 (23.3%) of the uploaded names had an exact match in the GBIF taxonomic backbone, representing 40,401,731 occurrences (36.7% of all). So there is clearly room for improvement.Some measures can be taken on the aggregator’s side to improve the matching process. For example, aggregators should optionally provide exact matches for minor discrepancies in name strings that do not reflect true differences, such as spacing in abbreviated author citations or removing designations like 'spp.' or 'Indet.' to match only the name-citing portion. Other corrections have to be made in the herbarium database itself, e.g., the addition of name authors where these are missing. We found that author citations or the lack of these, represented the main issue of non-exact matching in the data uploaded to GBIF.With local databases and aggregators improving their data and services, a subscription service using aggregator IDs as outlined in Berendsohn 2023 may become a realistic possibility in the near future. TETTRIs is assembling a wish list for aggregator services, which also includes the issues we have identified with the GBIF data submissions. We will further analyse these data and those from the herbaria of the authors' institutions to suggest priorities in data cleaning measures. We will consider how herbarium feedback can be leveraged to enhance aggregator datasets. We will also suggest measures for general collection management systems to facilitate name matching, starting with those used in our herbaria (JACQ, Specify).},

abstract = {Nomenclatural and taxonomic information are crucial for curating botanical collections. In the course of changing methods for systematic and taxonomic studies, classification systems changed considerably over time (Dalla Torre and Harms 1900, Durand and Bentham 1888, Endlicher 1836, Angiosperm Phylogeny Group et al. 2016). Various approaches to store preserved material have been implemented, most of them based on scientific names (e.g., families, genera, species) often in combination with other criteria such as geographic provenance or collectors.
The collection management system, JACQ, was established in the early 2000s then developed to support multiple institutions. It features a centralised data storage (with mirror sites) and access via the Internet. Participating collections can download their data at any time in a comma-separated values (CSV) format. From the beginning, JACQ was conceived as a collaboration platform for objects housed in botanical collections, i.e., plant, fungal and algal groups. For these groups, various sources of taxonomic reference exist, nowadays online resources are preferred, e.g., Catalogue of Life, AlgaeBase, Index Fungorum, Mycobank, Tropicos, Plants of the World Online, International Plant Names Index (IPNI), World Flora Online, Euro+Med, Anthos, Flora of Northamerica, REFLORA, Flora of China, Flora of Cuba, Australian Virtual Herbarium (AVH).
Implementation and (re)use of PIDs
Persistent identifiers (PIDs) for names (at any taxonomic rank) apart from PIDs for taxa, are essential to allow and support reliable referencing across institutions and thematic research networks (Agosti et al. 2022). For this purpose we have integrated referencing to several of the above mentioned resources and populate the names used inside JACQ with those external PIDs. For example, Salix rosmarinifolia is accepted in Plants of the World Online while Euro+Med Plantbase considers it a synonym of Salix repens subsp. rosmarinifolia. Either one can be an identification of a specimen in the JACQ database.
Retrieval of collection material
One strong use case is the curation of material in historic collections. On the basis of outdated taxon concepts that were applied to the material in history, "old" synonyms are omnipresent in historical collections. In order to retrieve all material of a given taxon, it is necessary to know all relevant names.
Future outlook
In combination with the capability of Linked Data and the IIIF (International Image Interoperability Framework) technology, these PIDs serve as crucial elements for the integration of decentralized information systems and reuse of (global) taxonomic backbones in combination with collection management systems (Gamer and Kreyenbühl 2022, Hyam 2022, Loh 2017).

abstract = {The World Flora Online (WFO) project (Borsch et al. 2020) was initiated in 2012 in response to Target 1 of the Global Strategy for Plant Conservation*1, "To create an online flora of all known plants by 2020" (Wyse Jackson and Kennedy 2009). A WFO Consortium of over 40 international institutions has been formed. The World Flora Online Public Portal*2 is built upon a taxonomic backbone of plant taxonomic data that integrates the International Plant Name Index (IPNI)*3, World Checklist of Vascular Plants (WCVP)*4, Tropicos*5, Angiosperm Phylogeny Group 4*6, Pteridophyte Phylogeny Group (PPG I 2016), supplemented by the Global Compositae Checklist*7, Solanaceae Source*8, and others. To facilitate the ongoing curation of the WFO backbone, identifiers called WFO-IDs have been created for each of the over 1.59 million names included in WFO. WFO-IDs are comprehensive for all known plants, both vascular and non-vascular except algae. IPNI-IDs are limited to vascular plants and do not give the current taxonomic status of the name. WFO-IDs also cover invalid designations, i.e., some effectively published “names” like orthographic variants that have been used in taxonomic literature, so that their invalid status is made explicit. WFO IDs follow FAIR principles (Findable, Accessible, Interoperable, and Reusable). Relationships between WFO-IDs are also recorded by the WFO Taxonomic Backbone, including synonymy and homonymy, and are accessible via the WFO Portal. WFO is continuously updating the taxonomic backbone by engagement of new plant Taxonomic Expert Networks (TENs) focused on selected plant groups. WFO also includes over 500,000 descriptive data items gathered from digital floras and monographs, and other sources. Descriptive data can be text descriptions, images, geographic distributions, identification keys, phylogenetic trees, threat status, lifeform or habitat. Descriptive data records are all assigned a WFO-ID, if they are new to WFO, by a name matching process with the WFO Taxonomic Backbone. A new tool called Rhakhis (Hyam et al. 2022), developed at Royal Botanic Garden, Edinburgh, is used to manage the WFO Taxonomic Backbone data and includes APIs to access the versioned backbone data. This presentation will review the origins and history of WFO-IDs and how they are being used for the World Flora Online.},

abstract = {One of the tasks of the EU TETTRIs (Transforming European Taxonomy through Training, Research and Innovations) project is to document and enhance the mapping of local taxon lists (or scientific data holdings containing lists of taxon names) to global and European aggregators of scientific names and taxa. Local lists are here understood to range from spreadsheets maintained by individual researchers to large databases containing taxonomic checklists for countries or entire regions of the world (e.g., the European plant checklist Euro+Med PlantBase). Unique and resolvable name identifiers (IDs) play a central role, because they allow tracking of name usage in the target aggregator. Aggregators should (and some do) provide name matching services that provide stable resolvable name IDs that users may incorporate into their databases. So, why would the administrators of such local lists want to relate their name data to global aggregators, for example to Catalogue of Life, World Flora Online or EU-Nomen? We are collecting such use cases and from those we will propose mechanisms to improve name matching and other services provided by the target aggregator systems. Simple use cases such as checking the names of a local list of insects against the names in the normative European EU-Nomen checklist (a.k.a. Pan European Species Infrastructure PESI) are already largely covered by existing name checking mechanisms. They are often used to detect orthographical or taxonomic errors. On the other hand, a common use case in the elaboration of taxonomic treatments with comprehensive cover of the names in the taxonomic group is to identify existing names that have to be investigated for that purpose, i.e., to identify names held by the aggregator that are not already in the treatment. Currently, this use case is not covered by a simple mechanism or service. Another common use case is that local data portals include links to aggregator databases when displaying a name (e.g., Tropicos). This allows linking to the name record in the target aggregator and thus (directly or indirectly), to the target's current or versioned taxonomic concept related to the specific name, and its opinion regarding the nomenclatural status. However, this is accomplished by using the name string as the search parameter, which may or may not work correctly. In contrast, the incorporation of the target aggregator's resolvable ID in the local database establishes an unequivocal link between the local name and the name in the aggregator treatment. This brings about an improvement in data quality for such links. Beyond that, users who did match their names should have the possibility to use a "taxon concept subscription" to be automatically informed of changes in the name usage of their names. This implies that target aggregators of taxonomic data trace changes in the concepts of the taxon where they place a respective name. These may be changes in status (accepted name to synonym or vice-versa) but also the addition of new synonyms to the concept, or the removal of synonyms. We hope that TETTRIs can instigate the implementation of taxon concept subscriptions by target aggregators. Nomenclators (databases that do not treat the taxonomic status of a name) would have to trace changes in nomenclatural notes or status of the name. In the two years remaining for this task in the TETTRIs project, we will continue to test and document services provided by the aggregators and promote the usage of name IDs in local systems and publications, in order to contribute to a linked data landscape for biodiversity information.},

abstract = {Herbarium collections shape our understanding of Earth’s flora and are crucial for addressing global change issues. Their formation, however, is not free from sociopolitical issues of immediate relevance. Despite increasing efforts addressing issues of representation and colonialism in natural history collections, herbaria have received comparatively less attention. While it has been noted that the majority of plant specimens are housed in the Global North, the extent and magnitude of this disparity have not been quantified. Here we examine the colonial legacy of botanical collections, analysing 85,621,930 specimen records and assessing survey responses from 92 herbarium collections across 39 countries. We find an inverse relationship between where plant diversity exists in nature and where it is housed in herbaria. Such disparities persist across physical and digital realms despite overt colonialism ending over half a century ago. We emphasize the need for acknowledging the colonial history of herbarium collections and implementing a more equitable global paradigm for their collection, curation and use.},

abstract = {Cultural heritage images are among the primary media for communicating and preserving the cultural values of a society. The images represent concrete and abstract content and symbolise the social, economic, political, and cultural values of the society. However, an enormous amount of such values embedded in the images is left unexploited partly due to the absence of methodological and technical solutions to capture, represent, and exploit the latent information. With the emergence of new technologies and availability of cultural heritage images in digital formats, the methodology followed to semantically enrich and utilise such resources become a vital factor in supporting users need. This paper presents a methodology proposed to unearth the cultural information communicated via cultural digital images by applying Artificial Intelligence (AI) technologies (such as Computer Vision (CV) and semantic web technologies). To this end, the paper presents a methodology that enables efficient analysis and enrichment of a large collection of cultural images covering all the major phases and tasks. The proposed method is applied and tested using a case study on cultural image collections from the Europeana platform. The paper further presents the analysis of the case study, the challenges, the lessons learned, and promising future research areas on the topic.},
