As with any model declaration, the FRBR-LRM text presents a description of the model in a way that is intended to be complete in itself, but cannot cover the reasoning behind the decisions taken or describe the alternatives that were ultimately rejected. In this brief discussion, I have highlighted some of the areas in which FRBRLRM innovates with respect to the previous models in the FRBR family and provided some of the considerations that led the Consolidation Editorial Group to the solutions adopted. All these decision points led to consequences for other aspects of the model, as the goal is to produce a single consistent model. Many of these issues have been discussed in one form or another since the initial publication of FRBR in 1998. I do not doubt that discussion of the most effective and useful ways of modelling bibliographically relevant phenomena will continue through the next steps in the completion and adoption of FRBR-LRM, and beyond.
