In other words, when x3d browsers and tools support import and export of json, then authors can do special stuff to aid them in the complex job of authoring. For instance the current gltf was designed by people that understand generation and maintenance of a complex scene graph and so if x3d supports gltf json then x3d author can use those data structures relatively easily in an environment that can actually validate the scene content prior to execution. So, that is where ordinary json fits in with x3d. Just another general purpose tool very useful for handling various sorts of data involved in authoring and delivering realtime interactive 3D viz using WWW. </p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>So, if I choose to define sets of data that I want to use and call by some name and it fits a json standard form, then I ought to be able to do so freely. For example, If I have an HAnim skin field, I want to be able to store that in my json file then the user code gets lots more simple because in place of the list of points, I just have a reference to the json file. However, I do not wish to encode an entire scene graph using json. So, for general validation of json content, I think two levels: First if the author has not provided a schema then it is only necessary to check for valid data json structures. Second, if the author provides a schema then look at names, data structures, and types. </p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>And, json files can include both authortime and runtime stuffs, at more or less the author’s choice. So the important item is not to limit the long-term potential of a feature like json for some relatively simple stuff while not unnecessarily promoting it use as a specialized syntax to describe and validate the entire scene graph. </p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>Thanks, and Best, </p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>Joe</p></div></div><div><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'> </p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'> </p><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><b>From: </b><a href="mailto:yottzumm@gmail.com" target="_blank">John Carlson</a><br><b>Sent: </b>Tuesday, January 24, 2023 12:36 AM<br><b>To: </b><a href="mailto:brutzman@nps.edu" target="_blank">Brutzman, Donald (Don) (CIV)</a>; <a href="mailto:gpugroup@gmail.com" target="_blank">GPU Group</a>; <a href="mailto:joedwil@earthlink.net" target="_blank">Joe D Williams</a>; <a href="mailto:michalis.kambi@gmail.com" target="_blank">Michalis Kamburelis</a>; <a href="mailto:myeongwonlee@gmail.com" target="_blank">Myeong Won Lee</a><br><b>Cc: </b><a href="mailto:x3d-public@web3d.org" target="_blank">X3D Public Mailing List (x3d-public@web3d.org)</a><br><b>Subject: </b>Re: [x3d-public] X3D Working Group agenda 20 JAN 2023: comment reviewfor C, C++, C# draft specifications</p></div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'> </p><div><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>Don, I’m hoping you can add “JSON for SAI—X3DJSONLS.*” to the schedule for the 27th. I need to figure out if there’s a niche for JSON in browsers with SAI and no DOM. In particular, optional scene validation with SAI generated from X3DUOM would be a great addition if not already provided when JSON is loaded into the scene with SAI. One thing i faced with C++ was I wasn’t aware of any SAI implementations; is now a good time to ask?
