Abstract
The workshop-hackathon was convened by the Global Biodiversity Information Facility (GBIF) at its secretariat in Copenhagen over 22-24 May 2013 with additional support from several projects (RCN4GSC, EAGER, VertNet, BiSciCol, GGBN, and Micro B3). It assembled a team of experts to address the challenge of adapting the Darwin Core standard for a wide variety of sample data. Topics addressed in the workshop included 1) a review of outstanding issues in the Darwin Core standard, 2) issues relating to publishing of biodiversity data through Darwin Core Archives, 3) use of Darwin Core Archives for publishing sample and monitoring data, 4) the case for modifying the Darwin Core Text Guide specification to support many-to-many relations, and 5) the generalization of the Darwin Core Archive to a “Biodiversity Data Archive”. A wide variety of use cases were assembled and discussed in order to inform further developments.
Highlights
Darwin Core (DwC) is a glossary of terms commonly used in the biodiversity domain
An enhanced DwC standard is essential to support the data needs and interoperability challenges posed by global biodiversity networks such as the Group on Earth Observations Biodiversity Observation Network (GEO BON) [56], which will underpin the work of policy and decision makers, including the recently established Intergovernmental Panel on Biodiversity & Ecosystem Research (IPBES) [57]
Adopting DwC and the Integrated Publishing Toolkit (IPT) as described in this report will help ensure that this popular standard becomes even more successful by enabling the encoding of a wide variety of sample-based data
Summary
Darwin Core (DwC) is a glossary of terms commonly used in the biodiversity domain. It was originally conceived to facilitate the discovery, retrieval, and integration of information about modern biological specimens, their spatiotemporal occurrence, and their supporting evidence housed in collections (physical or digital). As a glossary of terms, the Darwin Core provides stable semantic definitions with the goal of being maximally reusable in a variety of contexts This means that Darwin Core may still be used in the same way it has historically been used, but may serve as the basis for building more complex exchange formats while still ensuring interoperability through a common set of terms. The extensions provide a means of serving multiple identifications for a specimen, multiple images of a specimen, or multiple common names for a taxon This is possible due to the broadening of scope of the Darwin Core and a redefinition of its structure into a reusable glossary of terms. Review the merits of modifying the Darwin Core Text Guide specification to support many-to-many relations, and assess the potential generalization of Darwin Core Archive to a “Biodiversity Data Archive”
