No Managed Metadata columns in Power Query

When using Power Query to retrieve data from an O365 SharePoint list, you run into trouble when that list data contains columns connected to the Term Store (managed metadata).

These columns are not retrieved by Power Query, not using the "SharePoint List" connection and also not using the "oData" connection.









So, the managed metadata column "organisatie eenheid" is in this list:















But not in the Power Query result sets (oData):
Or in the "From SharePoint List" resultset:





I've notified Microsoft of this issue here, let's wait and see if there are any workarounds or fixes !
Will keep you posted...

Update 24 June 2014:

Ben Martens from Microsoft searched around and asked the product team about this issue and unfortunately the conclusion is that right now, it's not possible to get MMD data extracted from SharePoint.
Both the ListData.mvc as OData connections won't bring back these columns from your SharePoint lists.
Sorry for you ...
Let's hope these services get modified by the SharePoint team and start exposing this data, there are many scenarios where people really want to work with the Managed Metadata ! (why use it if it's not supported !?!). Thanks Ben for this update !
