Most of existing efforts in digital preservation have focused on extending the life of documents beyond their period of creation, without taking into account intentions and assumptions made. However, in a continuously evolving setting, knowledge about the context of documents is nearly mandatory for their continuous understanding, use, care, and sustainable governance. In this work we propose a method that considers the preservation of a number of interdependent digital entities, including documents, in conformance with context related information. A change that influences one of these objects can be propagated to the rest of the objects via analysis of their represented dependencies. We propose to represent dependencies not only as simple links but as complex, semantically rich, constructs that encompass context-related information. We illustrate how this method can aid in fine-grained contextually-aware change propagation and impact analysis with a case study.
