Hi!
the area for a long time). I guess the more
difficult question then, is,
which RDF/SPARQL implementation to choose (since any such implementation
should cover as least points 1, 2 and 4 in a similar way), which in turn
reduces down to the distinguishing questions of performance, licensing,
distribution, maturity, tech support, development community, and
non-standard features (keyword search), etc.
We indeed had a giant spreadsheet in which a dozen of potential
solutions (some of them were eliminated very early, but some put up a
robust fight :) were evaluated on about 50 criteria. Of course, some of
them were hard to formalize, and some number were a bit arbitrary, but
that's what we did and Blazegraph came out with the best score.
If you want to go into Wikidata history, here is the "giant spreadsheet"
Stas was referring to:
Some criteria there are obviously rather vague and subjective, but even
when disregarding the scoring, it shows which systems have been looked at.
