Inventorying life: New standards and approaches for re-using and integrating taxonomic inventory data
Results/Conclusions: We provide a very quick overview of terms from Humboldt Core needed to capture geospatial, temporal, taxonomic and habitat scope along with methodological descriptors related to assessment of sampling effort and inventory completeness. For the area species checklists application profile, we describe as well novel aspects such as effort in compiling previous data resources such as expert knowledge, museum specimen data, and prior literature, along with a method for assigning initial completeness metrics. We next describe how Humboldt Core has been successfully applied to a major effort to ingest and provision inventory data and metadata into the Map of Life project. A key output of the metadata ingest is an initial assessment of reporting quality and completeness drawn from 129 published inventories of terrestrial vertebrates, which is only possible given the standardization of outputs afforded by Humboldt Core. Our preliminary results show that only a minority of pubished area species checklists have sampled focal taxonomic groups completely, but many do utilize multiple inventory processes, including compiled (as opposed to primary-collected) data. We close by discussing next steps in further development, and integration into existing standards and ontologies, of this critical new standard for biodiversity science.
