The World Flora Online (WFO) project was initiated in 2012 in response to Target 1 of the Global Strategy for Plant Conservation – "To create an online flora of all known plants by 2020" (CBD 2010, Wyse Jackson 2013). A WFO Consortium of 50 international institutions and growing has been formed (see Wyse Jackson and Miller (2015) for a historical o...

With the increasing amount of interdisciplinary and international networks dedicated to long-term persistence and interoperability of research data, the demand for semantic linking of environmental research data has grown. Data related to organisms frequently inherit a major obstacle. Organisms often are ambiguously identified by using only the sci...

This data paper presents a largely phylogeny-based online taxonomic backbone for the Cactaceae compiled from literature and online sources using the tools of the EDIT Platform for Cybertaxonomy. The data will form a contribution of the Caryophyllales Network for the World Flora Online and serve as the base for further integration of research result...
Article
Full-text available
It is time to synthesize the knowledge that has been generated through more than 260 years of botanical exploration, taxonomic and, more recently, phylogenetic research throughout the world. The adoption of an updated Global Strategy for Plant Conservation (GSPC) in 2011 provided the essential impetus for the development of the World Flora Online (...

Full-text available
Plants, fungi and algae are important components of global biodiversity and are fundamental to all ecosystems. They are the basis for human well-being, providing food, materials and medicines. Specimens of all three groups of organisms are accommodated in herbaria, where they are commonly referred to as botanical specimens. The large number of spec...

For the last 15 years, Biodiversity Information Standards (TDWG) has recognized two competing standards for organism occurrence data, ABCD (Access to Biological Collections Data; Holetschek et al. 2012) and DarwinCore (Wieczorek et al. 2012). These two representations emerged from contrasting strategies for mobilizing information about organism occ...

The International Code of Nomenclature (ICN) for algae, fungi, and plants provides for nomenclatural indexing through nomenclatural repositories (Turland et al. 2018, Art. 42). Registering nomenclatural novelties and nomenclatural acts means that repositories will keep track of names (species names and names at all ranks, replacement names, names p...

Article
Full-text available
Herbarium specimens have always played a central role in the classical disciplines of plant sciences and the global digitisation efforts now open new horizons. To make full use of the inherent possibilities of specimen based taxonomic descriptions corresponding workflows are needed. A crucial step in the comparative analyses of organisms is the pre...
Article
Full-text available
The ongoing paradigm shift in taxonomy from individual contributions to a truly collaborative and forward-looking endeavour results in a number of challenges related to distributed data management. Examination of physical specimens remains a key task, but searching for specimen data, literature, and name information is now mostly done online. In th...

The Caryophyllales Network strives to assemble an online dynamic synthesis of the order Caryophyllales, uniting the current knowledge about the phylogeny of the order with up-to-date information on the individual taxa contained. Capturing taxonomic data and the decision processes involved in the definition and circumscription of the taxa requires h...
Article
Full-text available
Over the past years, herbarium collections worldwide have started to digitize millions of specimens on an industrial scale. Although the imaging costs are steadily falling, capturing the accompanying label information is still predominantly done manually and develops into the principal cost factor. In order to streamline the process of capturing he...
Article
Full-text available
On herbarium sheets, data elements such as plant name, collection site, collector, barcode and accession number are found mostly on labels glued to the sheet. The data are thus visible on specimen images. With continuously improving technologies for collection mass-digitisation it has become easier and easier to produce high quality images of herba...
Article
Full-text available
A simple, permanent and reliable specimen identifier system is needed to take the informatics of collections into a new era of interoperability. A system of identifiers based on HTTP URI (Uniform Resource Identifiers), endorsed by the Consortium of European Taxonomic Facilities (CETAF), has now been rolled out to 14 member organisations (Güntsch et...
Article
Herbarium specimens have always played a central role in plant sciences and constitute the cornerstone for systematics and taxonomy. This role is further strengthened with the ongoing digitisation and growing online-availability of collections all over the globe. The increasing usability of specimens demands, however, an improved use and sustainabl...

One of the major design features of the Common Data Model (CDM) is the ability to store and handle taxonomic concepts (a.k.a. “potential taxa” -Berendsohn 1995 , “taxonyme” - Koperski et al. 2000, "Assertions" - Pyle 2004, "taxonomic entities" -Kennedy et al. 2005 “taxon circumscriptions”, etc.). A major driver of the critical appreciation of the...
