Hi Annika,

"Our aim was to decide on a set of criteria that represent the quality 
of a data source. In this document, we understand a data source as an 
access point for Linked Data in the Web."

Does this mean that you consider only information services that follow 
the Linked Data principles? So would you exclude existing information 
services e.g., Wikipedia, MusicBrainz, Last.fm, Discogs, Echo Nest?
I think it is crucial to have information service quality ratings 
especially for this kind of information services, because they are 
currently the backbone of the existing Linked Data services that do 
Linked Data information providing and information integration tasks.

The aim of my thesis is to draw up a set of criteria to assess the quality of Linked Data sources. My findings include eleven criteria grouped into four categories. Each criterion includes a set of so-called indicators. These indicators constitute a measurable aspect of a criterion and, thus, allow for the assessment of the quality of a data source w.r.t the criteria.

OT: I think in a community it is quite natural to honour the people 
somehow, when they contributed useful (!) feedback. You might consider 
this ;)
