Goals
- Review of approaches of DDI 4 (see below)
- Inter-operability with other specifications. We realize that users want to use multiple specifications, and that there is a partial overlap between specifications. Therefore:
- Usage of DDI with other specifications should be explored
- Integration of other specifications on the model or binding level
- Description of partial overlap between specifications
- Building a basis of future cooperation between the groups of different specifications
...
- Model-based and –driven approach
- Better robustness and independence of a single representation
- Multiple bindings (i.e. XML Schema for preservation and exchange, RDF for discovery, program libraries for processing)
- Easier inter-operability with other specifications
- Better coverage of data life cycle, and generalization of data sources and data description
