Cargo seems promising as a lightweight data storage (though it would be good to include
Wikidata Q numbers for future federation). I notice Z's question at
[
https://wikispore.wmflabs.org/wiki/Talk:Cargo] about the desirability of a beginner's
tutorial on using Cargo: that doesn't appear to have been answered?
If there was such a tutorial, what I would really like to see is an example of moving from
data table query to rendering it - as Peter says above "on maps and/or timelines
and/or network graphs". If that is feasible/easy, that would be a strong foundation
for showing these new forms of knowledge.
