Aha, I think we're getting closer!
I poked around in the file
./exhibit/src/webapp/extensions/time/time-extension.js
as you suggested, and it looks like there is a change you have to
make. It turns out in that file, it loads timeline stuff from
simile's server, and even further, I forgot that there's a whole
timeline project you'll have to check out. :-)
So, go ahead and check out from svn:
http://simile.mit.edu/repository/timeline/trunk
into a local directory somewhere.
Next, you'll have to change the time-extension.js file mentioned
above, to point to that directory, instead of simile's server. If
you look in the file you'll see:
var scriptURLs = [ "http://static.simile.mit.edu/timeline/api-2.0/
timeline-api.js" ];
Try changing that URL to a "file:// " URL to the timeline-api.js file
that you just checked out.
So I changed it to:
var scriptURLs = [ "file:///Users/gabrieldurazo/Classwork/urop/
timeline/src/webapp/api/timeline-api.js" ];
and now it works for me. Last time when I tried it I just used the
Firebug Firefox extension to look at the external calls it was
making, and didn't think to actually check it with my wifi disabled.
When I disabled the wifi, my local Timeline stopped working. But
after checking out the project and making that change, now it does
work locally, so I have high hopes.
Let us know if this does it for you!

For those following my efforts, I changed the subject line of this
thread to better reflect its content. I am trying to run Exhibit
with Timeline extensions completely offline on a laptop for a
demonstration.
To this point, David Huynh and Gabriel Durazo have offered very
helpful suggestions. You can see Gabriel's instructions (which are
essentially a superset of David's) below, which I have effected on
my machine. I'm here to report on the results of my attempts with
these new instructions. Hopefully when we get to the end of this,
I can wikify all this on the SIMILE wiki.
The short version is that these instructions make Exhibit work, but
not the Timeline extension aspect of it. When I try and load a
page that has a timeline in it, I get the error (from Internet
Explorer...maybe I should try Firefox): "Caught exception:
undefined. 'Timeline' is undefined." I'll recap exactly what I've
done and outline what I plan to try.
This assumes of course that you've already downloaded the full
source of Exhibit 2.0 from the Subversion repository. I have, and
stored it in a directory called "exhibit" that sits in the same
directory as the web page I am trying to create. For example...
Desktop/-|
|- index.html
|- exhibit/
|- lib/
|- src/
|- tools/
|- etc...
So according to both David and Gabriel, step one is to change the
line in exhibit/src/webapp/api/exhibit-api.js:
// change this line from false to true
var useLocalResource = falsetrue;
I did that. Next, Gabriel says there are spots where a C-like a ?
b : c expression contains a web reference ( http://127.0.0.1:8888)
that assumes you're running a local web server on port 8888. This
has to be changed to a local file URL. Gabriel, on a PC, a
reference to the C:\ drive has the slightly peculiar notation
file:///C:/ . On my machine, since everything is in the exhibit
folder in the same directory as my web file, I would make a change
like this...
var url = useLocalResources ?
// " http://127.0.0.1:8888/exhibit/extensions/time/time-
extension.js" :
" file:///C:/Documents%20and%20Settings/miller113/Desktop/
exhibit/src/ajax/api/simile-ajax-api.js " :
" http://static.simile.mit.edu/ajax/api-2.0/simile-ajax-
api.js ";
and as Gabriel points out I need to make the same sort of change in
the reference to the timeline extension in the same file...
if (includeTimeline) {
scriptURLs.push(useLocalResources ?
// " http://127.0.0.1:8888/exhibit/extensions/time/
time-extension.js" :
" file:///C:/Documents%20and%20Settings/miller113/
Desktop/exhibit/src/webapp/extensions/time/time-extension.js " :
" http://static.simile.mit.edu/exhibit/
extensions-2.0/time/time-extension.js ");
}
Now if I embed this in the head of my web page one assumes it will
work...
<script src="./src/webapp/api/exhibit-api.js?
views=timeline&bundle=false" type="text/javascript"></script>
...and the answer is, yes, Exhibit correctly displays the various
facets like the view facets and text search facet. But as soon as
I include a timeline facet, I get the " 'Timeline' is undefined "
error. So I have a couple of theories I'm about to explore.
* Perhaps the ./exhibit/src/webapp/extensions/time/time-
extension.js file has similar a ? b : c fixes needed?
* Can I have a web page with a timeline facet without having
Timeline's source tree stored locally as well? Maybe not.
In any case, I'll continue to work this and hopefully I'll have an
answer shortly. Gabriel and David, if something stands out among
the things I've observed, please let me know.

Hi Ed,
I'm pretty sure this is possible because I'm pretty sure I've done
it before. I know it definitely doesn't work with Safari (I did it
on a Mac), but I seem to remember having some success with Firefox.

Okay, actually I just tried it out and it worked for me, at least
on my Mac with Firefox. Here's what I did:
In the HTML, instead of loading the script from simile's servers,
you can load it from a local file, with something like this:
<script src="../../../api/exhibit-api.js?
views=timeline&bundle=false" type="text/javascript"></script>
Now, you'll have to change the exhibit-api.js file a bit:
One of the first lines you'll see is:
var useLocalResource = false;
Unsurprisingly, you'll change this to "true".
Now, you'll have to go through the file and change a couple places
where that variable is used, since by default it expects you to be
running a server on your own computer, so it tries to find stuff
at 127.0.0.1. So scroll towards the end of the file (or search
for "useLocalResource") and you'll see this:
if (includeTimeline) {
scriptURLs.push(useLocalResources ?
" http://127.0.0.1:8888/exhibit/extensions/time/time-
extension.js" :
" http://static.simile.mit.edu/exhibit/extensions-2.0/time/
time-extension.js ");
}
That little ? after the useLocalResources is basically a condensed
"if" statement. If useLocalResources is true, then do the thing
before the colon, otherwise do the thing after the colon. So now
go ahead and comment out the 127.0.0.1 line, and put in the
address on your local drive. Since my time extension folder is on
my local drive here:
/Users/gabrieldurazo/Classwork/urop/exhibit/src/webapp/extensions/
time/time-extension.js
I changed it to:
if (includeTimeline) {
scriptURLs.push(useLocalResources ?
// " http://127.0.0.1:8888/exhibit/extensions/time/time-
extension.js" :
" file:///Users/gabrieldurazo/Classwork/urop/exhibit/src/
webapp/extensions/time/time-extension.js " :
" http://static.simile.mit.edu/exhibit/extensions-2.0/time/
time-extension.js ");
}
I'm not exactly sure what it would be on Windows -- maybe
something like file://C:/...... You may have to play around with
it a bit. Actually, after some Google searching, I see this may be
somewhat of a stumbling block. Make sure you can at least just
open an ordinary text file locally with file:// before you try
messing with the javascript files.
You can change the Map one this way, too, though I don't know how
useful the map will be without an internet connection.
You have to do this type of change to the third useLocalResources,
in order to load the simile-ajax stuff. e.g:
var url = useLocalResources ?
// " http://127.0.0.1:8888/ajax/api/simile-ajax-api.js"; :
" file:///Users/gabrieldurazo/Classwork/urop/exhibit/src/ajax/
api/simile-ajax-api.js " :
" http://static.simile.mit.edu/ajax/api-2.0/simile-ajax-api.js ";

I hope this helps. I did this with Exhibit 2.0 since I don't have
1.0 on my computer. You can just get the whole deal with an svn
checkout.
svn checkout http://simile.mit.edu/repository/exhibit/branches/
2.0/ exhibit
I think some of this may be able to be avoided by just loading the
Timeline extensions directly from the HTML in a script tag along
the lines of:
<script src="../../extensions/time/time-extension.js"></script>
but I'm not sure. Maybe David or someone can chime in with a more
straightforward way of doing this.
Cheers,
Gabe

Uh, it's a little more complicated than just that. I looked at the
instructions to run Exhibit offline in the wiki. For starters, it's
for version 1.0. Secondly, I need it to run with the Timeline
facet,
which the instructions don't address.
1 - Is this even possible?
2 - Is it as simple as a bunch of find/replace operations?
3 - Are there even more web linkages that I haven't anticipated that
will have to be found and fixed?
