Curation for spatial scientific data products and processing

The new UK Digital Curation Centre (DCC) includes research activity at the University of Edinburgh that aims to protect and extend the life cycle of digital data products as they pass from producers to consumers. The DCC has identified the following topics as critical for maintaining the digital results of scientific and academic work: (1) providing provenance retrieval to increase the utility of published data products; (2) enabling the systematic annotation of data collections to extend the research record; and (3) enhancing data discovery and integration through comprehensive and unambiguous semantics. Preserving and presenting (curating) large collections of scientific data with a spatial aspect is challenging and some communities are unable to perform basic curation tasks within these collections. For example, there is a need, but no operational system yet, for annotating astronomy data collections so that an object in an individual sky image is consistently identified (through analytical evidence) across different, distributed sky image catalogs. Another problem area concerns collections of data products created through geospatial processing within geographic information systems (GIS). Here the principles of curation are often neglected, due in part to the lack of a definitive standard for describing spatial data manipulation. Our research agenda includes identifying techniques for annotating spatial data products of more than one dimension (using a case study of astronomy data) that build on the successes of systems for genomic annotation in the field of bioinformatics. We also plan to assemble a comprehensive classification scheme for geospatial transformations, and use this scheme to improve the semantics used for both retrieving the provenance of, and integrating, GIS data products.
