I don't have a lot of context on OData, but from what I can tell from a quick look at the site, it seems a closer comparison would be the JSON:API spec https://jsonapi.org/. Graphiti took a great deal of influence from that spec, and was originally much more directly coupled to it. Now it's the default serialization format, but not the only one. It would probably be possible to "speak OData" as well if that was a big need.
