There's always something happening on Wednesday evenings in the Tetherless World!
TWeD Talk, Wednesday, March 05, 2014, 7pm ET, Winslow Building on the RPI Campus
Please join us Wed, 05 Mar for the return of Tetherless Ph.D. recipient Jesse Weaver as he leads us in a discussion of some of his current work at the Pacific Northwest National Labs on RDESC, "Experiences Curating Science Metadata and Recommendations for Publishing Metadata"
ABSTRACT: "Experiences Curating Science Metadata and Recommendations for Publishing Metadata"
At present, much science metadata is utterly inaccessible (i.e., not shared), digitally inaccessible (i.e., not on the Web), or machine-incomprehensible (i.e., text). Although standard vocabularies like GCMD keywords and CF standard names are a step in the right direction, much more is needed in order to bridge the semantic gap between the detail of science metadata and the generality of posed questions. As part of the RDESC project, we attempt to demonstrably bridge this gap for a specific atmospheric science use case by incrementally developing an OWL ontology to accommodate the precision of various metadata, and by curating the metadata into semantically rich, RDF triples. The ontology and RDF data model enable us to meaningfully related heterogeneous metadata of varying precision from different sources. In this talk, I will primarily discuss the metadata curation effort that has taken place to date in RDESC and make recommendations for how to improve on publishing science metadata.
RDESC is a DOE/ASCR-funded project in collaboration with RPI that aims to facilitate discovery of science resources at the scale of the scientific community. The project involves the curation of existing science metadata, the development of recommendations for publishing science metadata, and the development of a prototypical web interface for discovering resources described by the curated metadata.
