The base operation about Metadata Service in sharepoint 2013

本文详细介绍了如何将元数据从SharePoint 2010站点迁移到SharePoint 2013站点，并重点阐述了元数据服务的基本操作，包括获取服务、获取组、获取术语集等关键步骤。

This blog will continue The steps of migrating metadata from SP site 2010 to SP site 2013, and the below is about The base operation about Metadata Service
