<p>Read 'em and weep, or just send back a response

<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>

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

etc. be are allow between SFStrings in an MFString in
XML, but I don't know about HAnim or X3DV4.<br>

<p>The above also indicates that ' is not a
good encoding for single-quote characters, although
it's OK XML.</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>

<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" moz-do-not-send="true">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"
moz-do-not-send="true">web3d.org</a> website to put
member documents? It's under "Documents" on the main
<a href="http://web3d.org" target="_blank"
moz-do-not-send="true">web3d.org</a> site. <a
href="https://www.web3d.org/about/documents"
target="_blank" moz-do-not-send="true">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 started adjusting these copies, found a lot of
differences with Efi's latest. Am using those
differences to add & test some new diagnostics. <br>
<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>
