Access Managed Metadata Navigation via JavaScript API?

Question

I'm trying to figure out how to access the navigation termset that I've created in SharePoint 2013 via the Javascript Api, so that I can use it in a SharePoint hosted app.

I'm not sure which library I need to include to access the termset bits and I'm not sure what all is available.  Does anyone know how to do this?

Not sure about the JavaScript API. Hope the below links can help you in some direction

It's CSOM but not javascript :(.

For accessing the Managed Navigation term set using JavaScript, the libraries to use are SP.Publishing.debug.js and SP.Taxonomy.debug.js.  You can find them in the folder Web Server Extensions\15\TEMPLATE\LAYOUTS.  These are Client OM libraries.  The class definitions and overall usage are very similar to the C# examples linked above, but there are some differences.  I would suggest to start with the general documentation for using Client OM with JavaScript:

"Differences Between Managed and JavaScript Object Models"

If your navigation operations are read-only (i.e. rendering a navigation menu rather than editing it), you could also consider using the REST service.  It is documented here:

Hope this helps!

Did you ever find a way to get the terms from the managed metadata? I have got the site column (which has a term set associated), but I cannot get the terms for the site column.
