Interesting analysis! Do you also have insights into which JSON Schema constructs are used most often in that dataset?

Great post and really worth reading. Quite shocking insights, for example on the e-waste of BTC: "an average of one whole MacBook Air of e-waste per "economically meaningful" transaction".

I agree that once a project gets a bit more complex, these points are very important. In our low code platform ( https://github.com/dashjoin/platform ), you end up writing several JSONata ( https://jsonata.org&

I think so too. JSON Schema enables very useful tooling such as validation, Swagger-style UIs for interacting with services, or declarative web forms that people would have to build again and again.

There certainly are some similarities, but I think JSON-LD and and JSON Schema solve different problems. You might find this article helpful (I ended up writing this after being confused by the various standards in this space): https:&#x2F

A question that can only be answered with "it depends..." :) You might be able to simplify some of the queries using recursive SQL: https://en.wikipedia.org/wiki/Hierarchical_and_recursive_que... Neo4J is a v

Thanks! No, $doc2data is not a standard function. JSONata allows you to define your own functions ( https://docs.jsonata.org/embedding-extending#expressionregis... ). JSONata is great for transformation and we added functions

Dashjoin is an open source platform that allows you to easily extract, load, and transform (ETL) data into a database of your choice. We use JSONata, a powerful JSON query and mapping language, in conjunction with a graphical mapping editor

We scan the DB schema and suggest possible joins. The platform also supports basic CRUD operations using forms powered by JSON Schema. Would love to hear your feedback! Github: https://github.com/dashjoin/platform

Thanks for the link to the discussion on Github. I don't think it is a good idea to rely on inference (owl:sameAs) for something as basic as foaf:name vs. rdfs:label vs. schema:name, ... I have not used JSON API yet but it is cool to s

With your first point, you are talking about versioning (switching to a new IRI while keeping the old one for compatibility)? I agree that there probably is no value in using JSON-LD for an application that was built without LD in mind. Reg

The problem is the support matrix which is crazy in this area. I think ServiceNow did pretty well without having too many adapters (of course now they have quite a few - https://docs.servicenow.com/bundle/orlando-it-ope
