feature request: user-friendly working examples

[abubelinha]

Hi.
I was planning to use a simple spreadsheet to track work of volunteers in our institution, so I searched and found this repository and the publication: https://doi.org/10.5334/dsj-2019-054

I took a look and saw some graphical examples, plus some SQL-like queries.
Sorry, I don't know exactly what kind of language it is. The same one used in Wikidata?
Are those tables with the examples available somewhere?

I would like to see a tabular version of those examples, like a spreadsheet with columns representing all those examples of object-entities, curatorial-actions and curator-agents.

Also, do you know if there is any piece of open collection-databasing software already implementing all these ideas?
(or something similar)

Thanks a lot
