GPLv3 is quite limiting for a JS library. The source file[1] also has no license in the header, just a copyright.

You're looking at the minimized file. In source/js/timeline.js it says:

I posted an issue on github, recommending they include a license file in the main directory and switch to LGPL. Personally, I'm a fan of MIT/BSD, but if they prefer the GPL style, then the LGPL makes sense if they want the library to be used.

Could you explain why?

I've never been able to find a conclusive answer on GPL applied to Javascript

Your blog adds no content, please post direct links. Thanks.

This is gorgeous.

Thank you for making it open source.

Reminds me a lot of Simile Timeline (by MIT: http://www.simile-widgets.org/timeline/) but this looks so much better!

Thank you.

Building something simalaar to this was the only good idea I'd been harboring forna while now, but it will be interesting to see the feedback. I couldn't figure out how flexible to make it or what features to support, or if it should accept a file-based data structure for those not wanting to program an api. I guess I don't really know the audience.

Beautiful! I love the collapse/expand feature too.

One problem I have with the UI is that I feel the left/right arrows should ONLY be for going to different horizontal locations on the timeline, but they scroll through vertical locations as well if they are all at the same time. This was unexpected. Perhaps up/down arrows for the vertical navigation?

Looks good from the pics but on my iPhone it makes the website impossible to use. Scrolling and pinch to zoom doesn't work.

The site with the examples, timeline.verite.co, lists iPhone compatibility as an issue.

Very neat. There are no examples for parsing times instead of just dates that I can see (but it appears VMM.Util.parseDate supports it). Something like a timeline for server monitoring data would be a good use of this. Also, I would hope for a little more commercially friendly license for a library like this instead of the GPL.

Exactly what I was thinking. Can't wait to plug this into our custom Opsview (nagios) pages :D

Beautiful! Is anyone else slightly annoyed by the front-loaded easing when you click the arrows? (I have no idea if that is the right term, but I mean to say the fact that it starts slowly, then speeds up. I'd prefer the other way around).

Very cool.

I want to create a journal/blogging app which uses this as its main user interface.

Vertical scrolling option? (or at least scroll wheel support?)

Doesn't work very well on ChromeOS. Also, why is there no HTML "file format"?

Wonderful! I can't wait to have some free time to play with this!

Try the zoom buttons to experience the slickness. Very cool!

beats the heck out of facebook timeline!

Very neat!
