They were not the slaves, but unionized workers:

AFAIU an артель artelʼ usually did not engage in collective bargaining as such, so calling it a union is not really accurate; you might compare it to a guild but I think there’s no implicaton of a monopoly on a particular trade either. The most accurate description I can think of is perhaps a cooperative combined with a mutual insurance fund.

Agree, I might've stretched It a bit. Your descriptions is more accurate.

YEp, somewhat resemblance to Teamsters

Author here, feel free to ask me anything.

Btw, currently I have a huge backlog of telemetry to add, so I wouldn't mind some help. If anyone interested, have a look at the GitHub issues in this repo. The repo itself contains all docs and examples to get you started.

I've built a tiny pet project [0] that uses JSON Schemas [1] extensively.

Data is defined by the schema and it's used to build a static JSON API on GitHub Pages.

OpenAPI [2] definition for API reuses data schema and you can use OpenAPI Generator [3] to generate clients.

The site uses docsify [4] to display repo's README nicely.
