Integration of oreChem with the eCrystals repository for crystal structures
Download as PPTX, PDF1 like595 views
This document discusses integrating the oreChem ontology for representing scientific experiments and their provenance with the eCrystals repository for crystallography data. It describes how eCrystals represents crystallography experiments and data, the motivation for open access to research, and the oreChem ontology's concepts for representing methodologies, enactments, and provenance. It then outlines a proposed plugin for eCrystals that would map eCrystals data to oreChem concepts to capture the provenance of experiments and link data to the methods used.

Current Practice in CrystallographyCrystallography data is highly structuredThe de facto standard adopted by the community is the CIF (Crystallographic Information File)Relatively few crystal structures are openly published3http://www.rin.ac.uk/our-work/data-management-and-curation/share-or-not-share-research-data-outputs
