(I'm a member of the PartiQL team.) The language spec source will be open-sourced, as well, early next week (week of Aug 5). As I said above, to @ahl: Overall, we look forward to a community effort and participants that are interested in making significant investments to achieve the project's goals. We invite diverse opinions and viewpoints. As PartiQL grows towards a diverse community, we expect to add maintainers (for code and spec) that have non-Amazon affiliations and explore more formalized methods of governance.
