This API gives a way to attach "context" information to pieces of an RDF model by adding triples to the model itself. This is similar to reification but at a different, coarser, level. These tools use the concept of MSG (Minimal Self-contained Graph). Given a triple, the MSG that contains it is composed by that triple plus, recursively, for each blank node involved all the triples connected to it. An MSG therefore has a boundary consisting entirely of URIs or literals. An MSG is also the minimum "piece" of an RDF graph that can be can transferred to another peer that still allows the original graph to be incrementally reconstructed. This has been added to Deep Web Research Subject Tracer™ Information Blog.
