Hi Cindy, Deduping can happen in any number of ways, but making use of shared identifiers is the preferred way to address this issue. You could adopt a shared identifier or you can an indicate that your Thing is the same as a this other Thing. In schema.org's vocabulary, you'd use schema:sameAs [1] to achieve the latter. Short of a shared identifier, it becomes an exercise in comparing attributes (labels, other details) between two Things to determine sameness. It's best to make use of a shared identifier when possible. When it comes to the bibframe/schema distinction, this will work itself out in time. For a variety of reasons, organizations may choose to use Bibframe as a more library-specific vocabulary but publish the data for general consumption (read: for Google and others) in the schema.org vocabulary. If, over time, large volumes of data are published using the Bibframe vocabulary, and Google (or other engines) see a benefit to consuming Bibframe directly, then that's what they'll do. Whether Bibframe or schema, invoking shared identifiers will be more important to deduping entities than the vocabulary used.
