Programmatically Add the Site Collections to Have Read Only Access to the Local Site Collection Taxonomy Group in SharePoint 2013.

In this article you will see how to add the site collections to have read only access to the local site collection taxonomy group in SharePoint 2013 using the server object model.

Introduction

I have a site collection http://c4968397007/ in which I have created a taxonomy group. Navigate to the site collection http://c4968397007/. Click on "Settings", then click on "Site Settings".

Click on "Term store management" available under the Site Administration section. You will see the local site collection taxonomy group in the Taxonomy Term Store.



In SharePoint 2013, local term sets can be exposed to other site collections. This is one of the improvements in SharePoint 2013.
