An approach to modeling content for digital repositories

The process of managing production quality objects within a digital repository has created demand for designing content models that incorporate the principles of interoperability, extensibility, and standardization. We define a content model as a set of standardized behaviors encapsulating the data preserved by the digital object. The Tufts digital repository (TDR) content models provide a good base for flexible disseminations of data and contributes to inter-repository reuse and sharing of objects
