I want to start the managed metadata service. But when I browse Sharepoint Central Administration->Application Management->Manage Services on the Server , I don't find any Managed Metadata Service in the Service list. Moreover if I try to add a Managed Metadata Service from the Application Management->Manage Service Application after clicking on New I get a drop-down to create only a BDCS not a MMS. I am new to SharePoint 2010. Please suggest what could be the related issue.
SharePoint Foundation 2010 does not include the managed metadata service. You'll have to use SharePoint Server (Standard or Enterprise)
