(DEPRECATED for Jackson 3) Module for generating JSON Schema (v3) definitions from POJOs
Role in this project:Back-end Developer
Back-end DeveloperContributions:13 commits, 3 PRs, 6 comments in 1 day
Contributions summary:George primarily focused on improving the `fasterxml/jackson-module-jsonschema` repository, which is a module for generating JSON Schema definitions. Their contributions included deserialization implementations for various schema elements, such as `JsonValueFormat`, `ArraySchema`, and `ReferenceSchema`. The user also addressed issues related to serialization, including ensuring the correct format for the `JsonValueFormat` and fixing problems with the order of elements in `Set` during read/write cycles. These changes demonstrate a strong understanding of the internal workings of the JSON Schema generation process and the Jackson library.
