This DataONE OpenWetWare site contains informal notes for several research projects funded through DataONE. DataONE is a collaboration among many partner organizations, and is funded by the US National Science Foundation (NSF) under a Cooperative Agreement.

THIS PROJECT IS MID-DEVELOPMENT. RESULTS HERE ARE UNSTABLE, INCOMPLETE, AND PERHAPS WILDLY WRONG. That said, please enjoy your reading in the spirit of Open Notebook Science and I'd love to hear your thoughts and suggestions :)


Does the quantity of metadata associated with a dataset correlate with the number of times that dataset is reused?

Is more compete metadata associated with an increased benefit for investigators in the form of increased citations?



Downloaded ArrayExpress metadata using custom Python code on July 22, 2009. Open Source: <<link to git>>. (Note the one year gap. This was due to an intervening thesis. Also, updated metadata capture is not necessary because we would be ideally be capturing the metadata that existed at the time reusers would have been searching it... )

Identified ArrayExpress reuse in PubMed Central using the ArrayExpress variant of the DataONE:Protocols/Find_GEO_reuses protocol. Reuses captured on July 19, 2010

Downloaded Scopus citation counts for the PMIDs listed in the ArrayExpress metadata. Collected on July 19, 2010 using the DataONE:Protocols/Scopus_citation_counts_from_PMIDs protocol.
