MoReq2 is an evolutionary development of MoReq. The basic structures of the two specifications are similar, and they are based on the same concepts. However, there are many differences at a detailed level. The main differences are:

• MoReq2 is accompanied by a testing framework and a testing regime. MoReq had neither.  One effect of this is that the language used in MoReq is more precise and rigorous – which is why MoReq2 is much longer than MoReq.
• MoReq2 is under formal governance by the DLM Forum. MoReq was not governed.
• There is a roadmap for MoReq2 development; there was no roadmap, and no development of, MoReq.
• MoReq2 is accompanied by an XML schema. MoReq was not.
• MoReq2 is modular. There is a “core” of basic record keeping requirements, and optional modules for functionality that is needed by some organisations but not others.
• MoReq2 includes a metadata model that is much more complete than the model in MoReq.
• MoReq2 includes many functional enhancements compared to MoReq, such as sub-files and components.
