These distinctions do not entail that the dataset are really disjoint. In
fact, the VoID vocabulary introduces the subset relation, which relate a
dataset to its parts. For instance, we could have a dataset, which has
different subsets, corresponding to different linksets with other datasets.
In this scenario, the datasets and its linksets may share the same SPARQL
endpoint. However, knowing in advance that there exist some subsets that
provide interlinks may be useful: it is exactly the reason we use the LOD
cloud diagram.

The key idea behind the concept of void:Dataset is to provide metadata that
provide useful information about the actual data they refer to. In a sense,
a void:Dataset should provide information that help to understand the
usefulness of the data, to interpret the data, and so on.

If this ambiguity is unacceptable, we could consider alternative names for
the Lexicalization class. Perhaps, LexicalMapping or LexicoSemanticMapping,
or whatever sensible name.
