ISSUE-189: Aether VoID extension uses a different from the pattern that DQV inherits from DAQ

Hi all,

Several questions that came to mind regarding ISSUE-189.

1. "Aether - Generating and Viewing Extended VoID Statistical Descriptions
of RDF Datasets" [1] is specifically about RDF datasets, isn't it? So I
wonder whether its semantics might not fit with all types of data that DQV
should cover. However, I see that the ones that are shown in DQV such as
"number of distinct external resources linked to", "number of distinct
external resources used", and "number of languages used" are suitable for
most types of data.

2. I wonder whether it is possible (or makes more sense) rather than
including these raw statistics, whether they can be quality indicators that
are used by concrete quality metrics in dimensions such as completeness,
consistency, relevance, etc?

Best Regards,
Nandana
