Managing digital asset metadata: The value of flexible metadata models

Abstract

<p>Digital asset metadata cannot be represented by a single, unchanging metadata model and schema, because the metadata are too variable, complex, and change too rapidly. Data architects need to embrace flexible models that allow metadata to vary across asset types and that can accommodate changes to the underlying schema. While such flexible models can be implemented using traditional relational databases, they are generally easier to achieve with document and graph-oriented databases.</p>
