 <p>When we talk about things in the world in natural language and even when we assign identifiers, we are often imprecise in ways that make it difficult to clearly and unambiguously report provenance: a resource with a URL may be understood as referring to a report available at that URL, the version of the report available there today, the report independent of where it is hosted over time, etc.</p>

+<div class='note'>This is the single most important issue IMO: we hit readers with this "characterised thing" which is unexpected. We need to be absolutely clear about it...
+  <br/>ok, so it seems that characterized thing is introduced to deal with (1) imprecision, (2) disagreement amongst different "observers" of the same data-related events. I don't think this is about "disambiguation". It's about accommmodating different perspectives on the what is the same abstract "thing".  This interpretation fits with the example:  "different users may take different perspective..."</div>

 <p>Hence, to disambiguate things and their situation in the world as perceived by us, we introduce the concept <dfn id="concept-characterized-thing">characterized thing</dfn>, which refers to a thing and its situation in the world, as characterized by someone.</p>
