RDF Needs Annotations

While the current mechanism of reification in RDF is without semantics and widely considered inappropriate and cumbersome, some form of reification - speaking about triples themselves - is needed in RDF for many reasonable applications: in particular, reification allows for enhancing triples with annotations relating to provenance, spatio-temporal validity, degrees of trust, fuzzy values and/or other contextual information. In this paper, the authors argue that - besides resolving the issue of how to syntactically represent reification in the future (i.e., whether to stick with the current reification mechanism or standardize a different mechanism such as named graphs) - it is time to agree on certain core annotations that are widely needed.
