Remove a Site Collection's Read Only Access From Local Site Collection Taxonomy Group in SharePoint 2013

In this article you will see how to remove a site collection from having 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" under the Site Administration section. You will be able to 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. Please refer to http://www.c-sharpcorner.com/UploadFile/anavijai/cross-site-collection-term-set-access-in-sharepoint-2013/  to learn more about cross site collection term set access in SharePoint 2013. In my last article I explaind 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. (In this article I have added two site collections to have read only access to the local site collection taxonomy group.).
