Add KML placemark test 

It would be nice to have a test just for various types of KML placemarks,
to ensure that the parser avoids regression issues (and works correctly to
begin with).

Create Google Group for support 

too many folks are using the issue system or personal email for questions
that could be helpful to all - should create a Google Group for support.

json timemap issues in ie6/7 - works fine elsewhere 

What steps will reproduce the problem?
1. go to http://history.boisestate.edu/timemap/indexMapOnly.html


What is the expected output? What do you see instead?
should see a timemap. If you go there in ie6 or 7 the two bands are off by
12 years, the graphics are messed up and you can only scroll left so far.

What version of the product are you using? On what operating system?
happens only in ie6 or ie7. ie8, safari, firefox all work fine.

Please provide any additional information below.

Add "now" and custom function options to loadMgr onLoad function 

right now the onLoad function in the init script only allows scrolling to
the first or last event - it should also allow a "now" option, which will
somehow need to fire the onScrollListeners in order to display events and
hide past/future map items. It should also support an additional(?) custom
function in addition to the scrolling action (though scrolling probably
still needs to happen either way, because it's hard to sort out otherwise -
will need to think about how to support contexts in which the custom
function might override the scrollTo setting).

move loadMgr out of TimeMap.init() 

The internal loadMgr object in TimeMap.init() should be exposed as
TimeMap.loadManager, with a start() function that would reset the count,
take a new target, and accept an options object with functions, etc. This
will allow it to be used for better on-the-fly loading.

Move control functions to a separate file 

It might be nice to keep the timemap.js file solely for presentation stuff, 
and move functions like hideDataset(), scrollTimeline(), etc. that are 
meant for post-initialization control to a separate file - that way you 
could just use the timemap.js file if you weren't doing anything fancy.

Add more MapType flexibility 

There should be simpler management for map types in timemapInit() - you 
should be able to specify the set of map types as well as the default map 
type.

BC Dates 

I'm having issues inserting dates that are before 1000AD, the timeline
doesn't appear to support it.
Is this a known issue?

Add jsUnit tests 

The library is reaching a level of complexity where unit testing would be
helpful - would be helpful to have a suite of jsUnit tests to keep things
consistent.

Move to MIT or BSD license 

Upon examination, it doesn't really seem like the GPL makes sense for a
Javascript library. I'm going to move the code to a more permissive
license, either MIT or BSD.

TimeMap.init() should accept a date string or date object for scrollTo 

From
http://groups.google.com/group/timemap-development/browse_thread/thread/77cb0e58
e7ce4a67

I would like to be able to specify a specific date to the scrollTo
option, rather than earliest or latest.  This seems like it would be
an easy change (or am I missing something?) to ifLoadedFunction to
call setCenterVisibleDate with a provided date string rather than
getEarliestDate or getLatestDate from the eventSource.

This should probably support either a date string, parsed by hybridParser,
or a date object.

Allow nested datasets 

If all library interactions with the Item worked through an API (i.e. no 
calls to item.placemark or item.event), then you could stick a Dataset into 
the items array, expose the same API with dataset-appropriate responses, 
and allow users to zoom in on a given dataset, essentially expanding the 
nested items... this might be one approach to clustering/zooming events.

Filtering issue 

What steps will reproduce the problem?

1. Extract the zip file to a folder.
2. Run the .html file
3. Choose "EAT" from Category combobox.
4. Scroll timeline to July (between 20th and 28th)
5. Events do not appear on Timeline, but they do appear correctly on Googlemap.

What is the expected output? What do you see instead?
The expected output is to see all filtered events on Timeline and on
googlemap, of course.


What version of the product are you using? On what operating system?
Timemap v1.5
Timeline v2.3.0
All browsers are affected.

Please provide any additional information below.
I tested this in FireBug. I added console.log(item.event); at
the end of  filtering function. Now in FireBug, everytime I scroll the
TimeLine, I get the list of events. I picked some event that is not
visible on the timeline. And I tried to show it manually like this:
tm.timeline.getBand(0).getEventSource()._events.getEvent
('e14').item.show(); // e14 is the id of the event that is not visible
on the timeline band 0.

I also tried tm.timeline.layout(); this caused filtering to occur
again, but still items are not visible!

The weird thing is that everytime I try this filtering, events that
disappeared in the past, disappear again (exactly the same).  Now if I
put "return true" at the top of my filtering function, everything
works 100% fine.

Offer a zip file for download 

It seems like a zip file would work better than simply downloading the main
file. This will make it easier to package in the future, too.

Highlight effects for selected markers/events 

When a marker is selected on the map, the corresponding event should be
highlighted in the timeline.

Possibly, the marker and timeline event should both be highlighted on
selection.

XMLDocString Limit in getTagValue 

What steps will reproduce the problem?
1. Create a KML with a large data field (i.e. a LineString with many
coordinates)
2. getTagValue will only return the first 4096 characters (at least in
Firefox). 

Simple change, the function (line 838) only returns
nList[0].firstChild.nodeValue

Instead you should iterate through the "nextSibling" member on
nList[0].firstChild. 

verbose code shown below:
        if (nList.length > 0) {
            temp = nList[0].firstChild.nodeValue;
            nextSib = nList[0].firstChild.nextSibling;
            while(nextSib != null) {
                console.log("Appended a value.")
                temp += nextSib.nodeValue;
                nextSib = nextSib.nextSibling;
            }
            return temp;

Allow configuration to define timeline span for hiding map markers 

Right now, map placemarks not visible on the timeline are hidden on the
map. It might be nice to allow the developer to choose either a length of
time (extending both ways from the center visible date on the timeline) or
some visible overlay on the timeline for which map placemarks should be shown.

Original issue reported on code.google.com by [email protected] on 11 Mar 2008 at 9:37

custom Marker / Icon possible ? 

1. Is it posssible to use custom markers/icons in the timeline and the map ?
2. Can I define it in the KML file ?
3. Can you provide some examples, what kind of information can be used in 
KML files (how is the synthax for polygons for example)?

Thanks for your good work !

Allow items with missing placemarks or events 

Right now all items must have both a placemark and an event (i.e. both geo
data and time data), or they will be ignored on load. The system should
allow either one or the other to be missing (and maybe both? but I'm not
sure why you'd ever want that) - placemarks with no event would be
omnipresent on the map, and events with no placemark would just show up on
the timeline (and maybe open the info window in the middle of the map?).
This will require a bit of work, as the code currently assumes that both exist.

Support strategies for opening the info window 

Rather than setting a finite number of ways the info window should open,
you should be able to specify openWindow() and closeWindow() functions in
the options object passed to loadItem. TimeMap could provide a default, and
an Ajax variation, but could open this up for other developer strategies.

Create data service architecture 

Right now, I have loader functions, parser functions, and potentially
preload and transform functions. It would be better to consolidate these
into data service classes with a predefined interface. You could then make
services to load more specific data sources, like Google spreadsheets, as
separate classes - these classes would encapsulate the preload and
transform functions that are now separate (though presumably they could
take custom pl/t functions as well).

This would simplify the dataset syntax in TimeMap.init(), which I've never
been totally happy with, to something like this:

{
  id: 'ds',
  title: 'My Dataset',
  theme: 'green'
  type: 'kml' // service class name, or optionally a service class
  options: {  // all info necessary for the service
    url: 'myfile.kml'
    // you could potentially set preload/transform functions here,
    // to override the default options; metaweb, e.g., needs transform
  }
}

This avoids the awkward "data" element, and trying to choose what goes in
"data" and what goes in the core dataset object.

Then you'd create the service and load the data:

var svcClass = TimeMap.services[ds.type];
var svc = new svcClass(ds.options);
svc.load(dataset, callback);

This setup would also make it simpler to load remote data on the fly, after
initialization, and much simpler to add new services to a service library.

Add a README file 

There ought to be a README file in the distro tarball, explaining the
differences between the files and pointing to the examples and the wiki for
more information.

KML with empty tags breaks parser in Safari 

at line 439 in timemap.js, it says

 if (nList.length > 0) {
           data["options"]["description"] = nList[0].firstChild.nodeValue;
       }

this gives an error in Safari if the file has <description></description>

Probably anything that uses this construct may need an extra check to
ensure that the tag isn't empty - perhaps move this out to a utility function?

Support icons on a per-item basis 

The most basic way to do this is to check if "icon" is set in the JSON
data, and use it instead of the theme icon if it is. This would pave the
way for setting icons in KML.

Cluster events based on latlng 

Two possible approaches:

- Look at clusterMarker

- Use a latlng hash approach (store events in a hash table based on their
latlng)

Make TimeMap.init() dataset types pluggable 

Rather than including all of the supported dataset types in the
TimeMap.init() switch statement, it should be easier to plug in new parser
types. One thought about how to do this: Store loaders in an object
attribute of TimeMapDataset, e.g.

TimeMapDataset.loaders = {
  // start with basic loader
  basic: TimeMapDataset.basicLoader
}

Each loader function would take an object parameter "options", including
data, dataset, preload and transform functions, and the LoadMgr object (or
just the ifLoaded function?). Then each file that defined a new parser
would also define the loader, adding it to the TMD.loaders object.

So instead of the switch statement, we'd just have 

loader = TimeMapDataset.loaders[data.type];
loader(options);

This would decouple the loader logic from the init function, making it
easier to add new loaders.

hybridParser returns Invalid Date, not null, for invalid date strings 

TimeMapDataset.hybridParser uses Timeline.DateTime.parseGregorianDateTime
to parse stuff that's not ISO 8601. The Timeline function should return
null if the string to parse is invalid, but it doesn't - it returns an
Invalid Date object, which I'm not even sure how to check for. 

Should fix hybridParser, add a test, and possibly submit a fix for SIMILE.

User feedback indicates that a very simple demo page (perhaps one included

Hide placemarks before the timeline is final? 

It might make sense to hide all map placemarks when they're created,
showing them only once the timeline scrolls to its onLoad position... Would
need to think about how this might affect loading sequences in which new
items are added after the initial page load.

prototype.js breaks timemap 

Reproduction:
1. Include prototype.js (from http://prototypejs.org) in any page using
TimeMap.
2. Fire it up.

Output:
Error: iterator.bind is not a function, in prototype.js

The problem is line 212 in timemap.js.  It uses the for (x in
some_iterable) method of iterating over functions in filters.chain. 
Unfortunately, since prototype works by extending base objects like, say,
Object itself), there are some extra keyed items in the array Object, like
the each method, so in addition to calling the filter methods added by
TimeMap, prototypes each function also gets called and bonks.

I've attached a very simple patch that seems to fix the problem.

Support ExtendedData in KML 

There isn't any way to add arbitrary data to a KML file - it would be nice
to support basic name/value pairs in ExtendedData elements
(http://code.google.com/apis/kml/documentation/kmlreference.html#extendeddata),
just putting them into the item's "options" object.

Polygons don't hide on first map filter 

- normally, the sequence of loading and hiding goes like this:
1. items load, creating placemarks and adding them to the map
2. once all items are loaded, the map is filtered, hiding those not visible
on the timeline

- with polygons (and probably polylines), the sequence goes like this, as
far as I can tell:
1. items load, creating polygons and adding them to the map, but drawing
them takes time
2. once all items are loaded, the map is filtered. All polygons are told to
hide(). At this point, timemap.js thinks the polygons are hidden, AND the
polygons think they're hidden, but they aren't actually visible on the map yet.
3. the polygons finish drawing are are displayed on the map. Most of them
think they're hidden, but they get drawn anyway.

The issue here is that I don't think there's any way to know when the
polygons have finished drawing. This appears to be an asynchronous
operation, but I can't see anything in the GMaps API that can tell you (by
triggering an event) when it completes. The ideal would be to wait to
filter the map until after all the polygons are drawn (a fix to
TimeMap.init()); the less-than-ideal is to catch the "drawn" event outside
of TimeMap.init() and then show all items and filter them - but this still
requires knowing when the polygons have been drawn.

Add SIMILE-style XML parser 

It would be nice if folks who started using the SIMILE Timeline XML format
could just add lat/lon to their existing data, rather than reformatting as
KML or JSON - I should add an XML parser to parse that format.

Add clear() functions to TimeMap and TimeMapDataset 

Need to add more support for dynamic add and remove of datasets/items. 
There should be clear() functions for both datasets and items that remove 
events from the timeline, placemarks from the map, and items from the 
items[] array.
