Evidence claims

[sourced_fact] 'Open Source API and interchange format for editorial timeline information'; covers order and length of cuts and references to external media, not the media itself. · locator: repository description and README source
[sourced_fact] Core in C++ with official Python binding; adapters for Final Cut Pro XML, AAF, CMX 3600 EDL; native .otio/.otioz/.otiod. · locator: README source
