The next year or so will see linked data move from its current stage—characterized by conceptual discussion and experimentation—to prototypical development and pilot implementations. I anticipate that resource management systems might make the transition from MARC to BIBFRAME in the next 3 to 5 years. It is likely that systems would support BIBFRAME as an option rather than a wholesale replacement. The massive number of MARC records in use today will require a fairly long transition to any new metadata carrier.
