I've only just had a chance to catch up on this thread. I'm not
offended in the least by Turbomarc (anything round-trippable should
serve just as well as an internal representation of MARC, right?), but I
am a little puzzled--what are the 'special cases' alluded to in the blog
post? When would there ever be a non-alphanumeric attribute value in
MARCXML? Is this a non-MARC21 thing?

That trade-off ought to offend both camps, though I happen to think it's quite
clever.

I think you'd have a very hard time demonstrating any speed advantage to MARC
over MARCXML. XML parsers have been speed optimized out the wazoo; If there
exists a MARC parser that has ever been speed-optimized without serious
compromise, I'm sure someone on this list will have a good story about it.

Dear Nate,
There is a trade-off: do you want very fast processing of data -> go for binary
data. do you want to share your data globally easily in many (not per se library
related) environments -> go for XML/RDF.
Open your data and do both :-)

Hi all,
I've just spent the last couple of weeks delving into and decoding a
binary file format. This, in turn, got me thinking about MARCXML.
In a nutshell, it looks like it's supposed to contain the exact same
data as a normal MARC record, except in XML form. As in, it should be
round-trippable.
What's the advantage to this? I can see using a human-readable format
for poorly-documented file formats -- they're relatively easy to read
and understand. But MARC is well, well-documented, with more than one
free implementation in cursory searching. And once you know a binary
file's format, it's no harder to parse than XML, and the data's
smaller and processing faster.
So... why the XML?
Curious,
-Nate
