Research output: Contribution to journalArticle


Previously we asked, "When is a record data and when is it a fish?" (Wickett et al., 2012). In this work, we ask, "when and in what contexts are a record and a fish equivalent?" We describe and compare a collection of potentially equivalent records describing a Mola mola, or Ocean Sunfish, specimen. We calculate the Metadata Coverage Index (MCI) of each record and explore the use the Systematic Assertion Model (Dubin, 2010) to support investigation of the assertions contained in these data records.
