Are people out there still using XML Schema?


I'm genuinely curious. I'm a TSC member of JSON Schema and want to research more the remaining uses of XML Schema in the wild.

Do you know of any individual or organisation?

"using" is one of those weird words: the Maven XML build file (and its settings, and a few others) still have versioned XML Schemas: e.g. https://maven.apache.org/xsd/maven-4.0.0.xsd and its friends https://maven.apache.org/xsd/

If you mean "stood up a consumer-facing service whose contract is dictated by WSDL and/or XML Schema," then I'm guessing the broad answer will be no because it's not kewl

As a TSC member of JSON Schema, the best DX thing you can push through would be the xsi:schemaLocation replacement because right now mapping files to their schema is some damn tomfoolery

Heavily used within energy industry systems and standards we have to work with in Germany to integrate with. A couple of examples:

- Electronic delivery receipts for metering hardware (from standard body)

- API spec for smart meter interfacing software (from vendor, feels legacy-like)

- API to interact with official sub-CAs (from government authority)

- Definitions for EDIFACT files (from standard body)
