<p>Read 'em and weep, or just send back a response rebutting.</p>
<p>Enjoying the lively banter about standards. Is this what you
guys spend time doing?</p>
<p>Remember, people are spending their lives on this stuff. No
need to jerk them around excessively. Getting close to right
was literally a struggle, and we're not quite there yet for JSON
parsing with X3DJSONLD.java (or whatever it's called now). I
was aching over pretty much everything in XML, which is why *I*
prefer JSON (despite not having comments). It is an ECMA
standard. It has a large body of people who know and love or
hate it.</p>
<p>Suggestion, we at least do XML -> JSON -> XML in 2 wildly
different ways.<br>
</p>
<p>What should the new standard be?</p>
<p>In 5) I do not see why we have ""'s and also \"
very confusing. Oh, I get it, quotes within SFStrings.<br>
</p>
<p>So maybe I am just the foil to discuss this. I have yet to
find a detail in V4 that wasn't in V3.3</p>
<p>Drop a little data file in the archives, and poof, it explodes.</p>
<p>I'm hearing a suggestion that I go through the standard using a
fine tooth comb, because we are generating it from X3DUOM?</p>
<p>There is room for building prototypes before specifications.
Just look at how X3DUOM was created. I know it's not your
favorite way of dealing with things.</p></div></div><div><div><p><br>

<p>Please read the above and tell me what I'm doing wrong. This

X3DV4.<br>
</p>
<p>The above also indicates that ' is not a good encoding
for single-quote characters, although it's OK XML.</p>
<p><br>
</p>
<p>I'm not really sure where else to look for X3D Canonical Form,
clicked the first link on Google, dang, that's 3.3. Okay, I see
version="4.0" X3DV4 in the audio X3D files. But X3DV4 doesn't
cover XML encoding that I know of? I will look through the
drafts. Okay, I see:</p>

(I did try to read this).<br>
</p>
<p>Or:</p>
<p><a href="https://raw.githubusercontent.com/Web3DConsortium/X3D/master/ISO-IEC19776/ISO-IEC19776-3/ISO-IEC19776-3v4.0/ISO-IEC19776-3v4.0-WD1/Part03/concepts.html#X3DCanonicalForm" target="_blank">https://raw.githubusercontent.com/Web3DConsortium/X3D/master/ISO-IEC19776/ISO-IEC19776-3/ISO-IEC19776-3v4.0/ISO-IEC19776-3v4.0-WD1/Part03/concepts.html#X3DCanonicalForm</a>
(not found).</p>
<p>I don't see any way to show this except by downloading from the
github site. I have already seen the HTML--looks like
gobbledegook, as that's what's shown on github. Is there
another way to view github that will show the rendered file?<br>
</p>
<p>Looking here:</p>
<p><a href="https://www.web3d.org/specifications/" target="_blank">https://www.web3d.org/specifications/</a></p>
<p>I do see the 3.3 XML encoding standard referenced as first link
above.</p>
<p><br>
I don't really want to spend time downloading the standard yet.
Is there someplace you can privately share the rendered X3DV4
Canonical Form on the web for me as a member of web3d
consortium? Seems like creating a member accessible version
would be very handy for collaboration, and then there would be
no disagreements (which version do you have, etc.).</p>
<p>This might be a good place on the <a href="http://web3d.org" target="_blank">web3d.org</a> website to put
member documents? It's under "Documents" on the main <a href="http://web3d.org" target="_blank">web3d.org</a>
site. <a href="https://www.web3d.org/about/documents" target="_blank">https://www.web3d.org/about/documents</a></p>
<p><br>
</p>
<p>I'm not sure I can share the X3D 4.0 XML encoding standard on
the mailing list? Should I contact you directly once I've
viewed the 4.0 version? So far, I've just viewed it on github.
Yes, I realize I am not up on all the encoding standards at this
time, mostly I am focused on getting JSON/JavaScript working.
My second priority is HAnim. XML is way down the list of my
priorities.<br>
</p>
<p>I'm a bit nervous having proprietary info on my computer right
now. A virus scan did not go perfectly (100 false positives),
so I'm a bit nervous. What I'll do is download the snapshot,
render and send a picture to Don directly, then delete my
version.<br>
</p>
<p>Thanks!</p>

Or better yet, refresh your version control later. I just

Efi's latest. Am using those differences to add & test some
new diagnostics. <br>

p.s. John you likely want to adjust your text output to match
X3D Canonical Form in order to avoid diffs when comparing
equivalent node definitions. <br>
