mpling event data have been introduced into the data publishing and indexing routines of the Global Biodiversity Information Facility (GBIF) in September 2015. These datasets typically derive from standard protocols for measuring and monitoring biodiversity like vegetation transects, bird censuses and freshwater or marine sampling. By indicating the methods, events and relative abundance of species recorded in a sample, these datasets improve comparisons with data collected using the same protocols at different times and places

In data publishing and the registration of datasets, sampling event datasets appear to form a class of data alongside species occurrence records, checklists of taxon names, and general dataset metadata. Yet, there are many similarities and overlaps that closely link sampling event data both with species occurrences and dataset metadata, as well as with the documentation of methodologies (sampling protocols). Some of these areas are widely understood and integrated, others, like the interoperable description of methods, will need more future effort for increasing the usefulness of sampling event data.

The presented poster aims at documenting the linkages between these classes of data, and to provide a basis for joint discussion and focusing of collaboration.
