Todd A. Carpenter has self-archived "What Constitutes Peer Review of Data: A Survey of Published Peer Review Guidelines."
Here's an excerpt:
Since a number of journals specifically focus on the review and publication of data sets, reviewing their policies seems an appropriate place to start in assessing what existing practice looks like in the 'real world' of reviewing and publishing data. This article outlines a study of the publicly available peer review policies of 39 scientific publications that publish data papers to discern which criteria are most and least frequently referenced. It also compares current practice with proposed criteria published in 2012.
