Semantic Annotation of Mutable Data

Figure 5

Linking using a SemanticTag.

The photo:owner assertion is more tightly coupled to the annotation than in [Figure 4] to the extent that it is acting on an object whose type is a class on OA. The Open World Assumption notwithstanding, if the photo:owner predicate were removed, the foaf:Person would be unrelated to the annotation, and the tag would carry no knowledge. In this case, a consumer of the annotation could reasonably conclude that it received an incomplete annotation. See [RDF S4] for complete RDF.
