You may want to start from their current development rather than starting from scratch. It looks like their license is the MIT license, which is very permissive.
If you do create a writer, I’d ask you to both keep us informed and request a writer id. https://github.com/apache/orc/blob/d082718a0bf8d703c96f3bf39ea02307498d1800/proto/orc_proto.proto#L211 <https://github.com/apache/orc/blob/d082718a0bf8d703c96f3bf39ea02307498d1800/proto/orc_proto.proto#L211> The writer ids are useful in case we need to work around bugs in a particular implementation.
