Apollo Transcripts: XML Data Format
By Eric Hartwell - last updated

For my Apollo 17 project I decided to use a generic
and extensible XML format for the timeline data instead of hard-coding the HTML. The
easily be applied using an XSLT style sheet.
The fundamentals of a transcript map directly to XML:
- who who="ID"
- what <quote>, <photo> etc.
- where src="source"
- when <event met="hhh:mm:ss">
Note: For the Apollo 17 transcript, NASA didn't timestamp each quote
independently as they did for all the others. This means there can be
several <quote> elements for each <event>.
||A significant occurrence or happening, usually time-related
||Mission Elapsed Time hhh:mm:ss
||Something spoken or written
||NASA photo ID
The simplest way to create and XML schema is to generate it directly from the
Here's a sample of the XML from my
Apollo 17 Flight Journal timeline:
have a liftoff. We have a liftoff and it's lighting up the area, its just
like daylight here at Kennedy Space Center as the Saturn V is moving off the
pad. It has now cleared the tower.</quote>
First Stage S-IC</h3>
The clock has started. We have you. (Laughter) Clear the tower. Roger;
tower. Yaw's complete. We're into roll, Bob.</quote>
- It was dark and we didn't see anything until S-IC ignition.</quote>
S-IC ignition - The lights started going out at 7 seconds, and somewhere
around 3 seconds they were completely out. You could feel the ignition. You
could feel the engines come up to speed. Just prior to lift-off and during
the first few seconds of lift- off when we were near the pad, both the CMP
and I could see the reflection of the engine ignition out the left-hand
window and the hatch window in the BPC. We could not see the fire but could
see a red glow through the windows reflecting apparently off the surface.
Ignition was like a big old freight train sort of starting to rumble and
shake and rattle and as she lifted off. We got a good tower clear.</quote>
really wasn't watching the lights because I guess I didn't expect the thing
to shake quite as much as it did. To me, I felt like I was really vibrating.
I wanted to find out what was making me vibrate. I wasn't expecting that
much vibration when the S-IC lit off. At lift-off, again, once it got
vibrating, I didn't feel the yaw. I was watching the needle on the thing but
didn't feel the yaw, though.</quote>
flight - During the actual powered flight of the S-IC you could not see
anything at all. You couldn't see out the cockpit, as we had the lights up
Geno. Looking great. Thrust good on all five engines.</quote>
babe. It's looking good here; roll is complete. We are pitching.</quote>
babe. Let's check the angles.</quote>
is Mission Control. Gene Cernan reporting the launch vehicle maneuvering to
the proper attitude, everything looking good at this point.</quote>
seconds. We're going up. Man, oh, man!</quote>
seconds, and 17 is GO.</quote>
17, you're GO.</quote>
stage looks good. Altitude 1.1 miles. Booster says we look good. We are now
at 2.5 miles.</quote>
