Abstract

The Access to Biological Collections Data (ABCD) schema is designed to facilitate the exchange of biological collection units, including living and preserved specimen, along with field observation data. It was ratified as a standard by TDWG in 2005. However, the natural history collections typically include also non-biological geoscientific items. Therefore, the Extension for Geosciences (EFG) extends the ABCD schema to integrate geological data, including information about paleontological and geological collection items. Its elaboration started in the framework of the EU-funded project SYNTHESYS and was accompanied with the development of the Geoscientific Collection Access Service (GeoCASe) portal. The aim is to provide a standard for petrological, mineralogical, and paleontological collection data in order to facilitate their exchange and publication.

Background

The existing schema Access to Biological Collection Data (ABCD) has been extended in order to cover the different earth science disciplines, widespread in large museum collections. The resulting Extension for Geosciences (EFG) schema is very granular and allows a detailed description of geoscientific objects. It comprises a broad range of properties regarding geological and geomorphological observations; geological specimens and their preparations; paleontological, mineral, rock and sediment specimens; anomalous items (e.g. glacial erratics, transported assemblages); stratigraphic and absolute dates; measured stratigraphic sections and borehole logs; identifications (extended to cover rock and mineral classifications, varietal names etc.), analyses (techniques and results e.g. chemical composition of minerals, petrological analysis of rock); integrated description of the host rock as part of a unit record (e.g. mineralisation and alteration of ammonite specimen). The Development of the ABCDEFG schema for earth science started in 2005. In the framework of the EU-funded project SYNTHESYS the Geosciences Collection Access Service (GeoCASe, http://www.geocase.eu/project, lead Museum für Naturkunde Berlin) and a first data model for geoscience was developed to make earth science collection databases openly and universally available on the internet. GeoCASe built on and extended the developments for the mobilization of data related to biological collection objects in the BioCASE project (The Biological Collection Access Service for Europe, EU-funded from 2001-2004). A team of 19 scientists and curators from several European institutions specified their requirements in two workshops (2005, 2007) and provided the basis for the first version of the schema.
