Appendix A. Changes between Version 1 and Version 2 of this specification
The major changes between Version 1 and Version 2 of Specification 1 are:
- Focus on the preservation requirements. Version 1 of this Specification included many requirements that were general functions of a recordkeeping system. There are many documents covering these general functions, and these documents are more complete than the requirements given in Version 1. Consequently, in Version 2 the focus of the Specification has been narrowed to those requirements that support long term preservation of electronic records.
- Explicit models of implementation. In Version 1 there were two implicit models of implementation: one where the recordkeeping system used VEOs as the internal data structure, and a second where VEOs were only produced upon export. In Version 2 these models are made explicit and the implications of these models are discussed.
- Specification of conformance requirements. Some of the specifications in Version 1 were difficult or impossible to test. In Version 2 information has been added about how to achieve conformance to requirements and who would normally be responsible for achieving conformance.
