It is described as one of the foundational technologies of REX, the staged next-generation project for RE ENGINE. Benchmarks shown deserialize JSON up to about 2.84 times faster than .NET's System.Text.Json, with results varying by data shape, environment, and CPU.","whyItMatters":"Capcom is giving away the data layer that large-scale RE ENGINE titles depend on, which lowers the odds that the tooling it needs is gated behind its own closed pipeline.","webCardHtml":"\u003cp\u003eThe release ran alongside the opening lecture of Capcom\u0026#39;s CAPCOM Open Conference RE:2026, which set out the outlook and future of REX, the staged upgrade of the company\u0026#39;s in-house engine. RE:Dox is a token-based structured data engine for .NET, and the published repository includes sample code for player data: converting a level 42 Leon with a handgun and a green herb into JSON, then reading it back to rename the character Claire and add a knife to the inventory. Capcom puts the library under Apache-2.0, which permits commercial use and modification under the license\u0026#39;s conditions.\u003c/p\u003e","blueskyPost":"RE:Dox is the piece of REX that does not need RE ENGINE to be useful. A JSON deserializer shipping under Apache-2.0 can land in projects that have nothing to do with Capcom's engine.","twitterPost":"RE:Dox ships under Apache-2.0, so the REX foundation Capcom just opened can be used by teams with no connection to RE ENGINE.","threadsPost":"RE:Dox does not require RE ENGINE to be useful.
