"REST" is our industry's most successful collective delusion: everyone knows it's wrong, everyone knows we're using it wrong, and somehow that works better than being right.

We have a little bit of runtime checks in the Java projections but it's still tied to SHACL/SPARQL through the Jena library. We are exploring ways to keep using SHACL at scale for …

It is important in UDA for the data models to be part of the same knowledge graph as the data container representations and the mappings, and eventually the instance data too. Our …

Exactly. In UDA, each Movie entity belongs to a specific business domain. Universality isn't an inherent truth, it's a social alignment within a group, useful only to the extent th…

This does look interesting. Does the Ash Framework yield a knowledge graph? How good is it a cataloging existing data containers?

UDA does not believe in the existence of universal data entities. We embrace the idea that 2+ teams may have different opinions on how to represent the world. We are focused on the…

We joke internally that Upper is like "RDF: The Good Parts".

> The whole point of GraphQL is to create a unified view of something, not to have 23 different versions of "Movie". GraphQL is great at federating APIs, and is a standardized API …

Great question. It really depends on the projection. For example, the projections to GraphQL and Java are mostly limited to what can be expressed there. But the projection to SHACL…

> I wonder how they deal with versioning or breaking changes to the model. Versioning is permission to break things. Although it is not currently implemented in UDA yet, the plan i…

> Of course, details on "Upper", PDM, and Sphere are well - missing, but at least I have concepts to focus on :) Definitely coming soon ;-)

The price is in the 500+ domain graph services federated into our GraphQL enterprise gateway, which will all be exposed to Sphere through UDA. That's real.

> How does this relate to domain-driven design? The "Domain" in `upper:DomainModel` is the same D as in DDD (Domain-Driven Design) as the D in DGS (Domain Graph Service). > in DDD …

> Would also be more than happy to skip the whole GraphQL end of it. Netflix benefits from a large GraphQL ecosystem with federation, which is why it's so central in UDA from day 1…

UDA embraces the duplication of models: it's a fact of life in the enterprise. That is why "domains" are first-class citizen. We believe that good discovery capabilities will incre…

> It is fundamentally a business problem, rather than a technical problem, but it has impact on development speed, so it's secondarily a technical problem. Yes it is a "fundamental…
