How to upload a document from a SharePoint Provider Hosted Addin to a Document Library on the Remote Host and complete required Managed Metadata fields

Hi,

Say I have a document library in a DEV02 site collection in SharePoint 2013.

The library (MyLibrary) has a required Managed Metadata column set on one of the fields (columns). 

I develop a provider-hosted SharePoint Addin to that site collection.

I want to provide within my addin the ability for  a user to upload a document into that MyLibrary document library.

If that were being done directly from the MyLibrary document library from within SharePoint then one would be prompted to choose one or more Managed Metadata terms.

But how can I present to the user within my addin those self-same managed metadata terms before he uploads the document?

Thanks

Maz
