In short, we wrote formal specification of Modern JSON Schema, with specific attention to unevaluated* keywords and to dynamic references, and we discovered many unexpected things, not last the fact that dynamic references, in their 2020-12 incarnation, make validation a PSPACE-complete problem, which was frankly unexpected (and may even be exploited for DoS attacks). Our formalization of dynamic references derives from discussions that I had in this group, and our understanding of annotation-dependent evaluation derives from following your discussions and experimenting with the tools that you realized, hence we owe a lot to the members of this group. The paper is available on<span> </span><a href="https://arxiv.org/abs/2307.10034?context=cs.DB" style="color:rgb(18,100,163);text-decoration:none!important;font-size:0.8125rem" target="_blank">https://arxiv.org/abs/2307.10034?context=cs.DB</a>, and we would really appreciate any kind of feedback. We would be delighted to answer any question or to present it again to the group - we presented some preliminary results a couple of years ago. The paper touches many points that I would like to discuss with you, if you believe that there is interest about our methods. In any case, thanks again for all your efforts in the JSON Schema project.</div></td></tr></tbody></table></td></tr></tbody></table></td></tr></tbody></table></div><div dir="auto"><br><table style="font-family:Lato,"Helvetica Neue",Helvetica,Arial,sans-serif;border-collapse:collapse;width:344px;color:rgb(67,66,69);font-size:17px;font-style:normal;font-variant-caps:normal;font-weight:400;letter-spacing:normal;text-align:start;text-transform:none;white-space:normal;word-spacing:1px;text-decoration:none"><tbody><tr><td style="font-family:Lato,"Helvetica Neue",Helvetica,Arial,sans-serif;font-size:17px;line-height:24px;vertical-align:top;padding-bottom:10px"><table style="font-family:Lato,"Helvetica Neue",Helvetica,Arial,sans-serif;border-collapse:collapse;width:342px;padding:0px;font-size:16px"><tbody><tr><td style="font-family:Lato,"Helvetica Neue",Helvetica,Arial,sans-serif;font-size:17px;line-height:24px;vertical-align:top;padding:0px 10px 0px 0px;width:36px"><img alt="" height="36" width="36" src="https://avatars.slack-edge.com/2022-03-15/3268296946832_9f8a2c0b4cfe58927768_72.jpg" style="border:medium;max-width:100%;margin-top:3px;display:block;border-radius:4px;width:36px;height:36px;min-width:36px"></td><td style="font-family:Lato,"Helvetica Neue",Helvetica,Arial,sans-serif;font-size:17px;line-height:24px;vertical-align:top;padding:0px 0px 20px"><table style="font-family:Lato,"Helvetica Neue",Helvetica,Arial,sans-serif;border-collapse:collapse;width:296px"><tbody><tr><td style="font-family:Lato,"Helvetica Neue",Helvetica,Arial,sans-serif;line-height:24px;vertical-align:top;padding:0px"><br></td></tr></tbody></table></td></tr></tbody></table></td></tr></tbody></table></div></div>
