Sharepoint 2013 : Managed Metadata in SharePoint Sites (part 1)

Terms within a Managed Metadata Service Term Store surface  in a collection of site via the special types of column of site. Assuming the administrator a site of SharePoint associated with the store of term contained in the Managed Metadata Service, the satisfied owners can add the new columns of meta-data to the lists, the satisfied types, and the Site Column Gallery. Table 1 details the different Managed Metadata site column types.

Note  New to SharePoint 2013 is the ability to drive site navigation from term store metadata within a publishing site collection.

Table 1. Managed Metadata Column Types

Managed Metadata Column Type	Description
Managed Metadata	Provides a column mapping to a term set in the site-associated term store; depending on the configuration of the term set, this type will depict whether users see all available term sets when selecting a term, have the ability to submit feedback to the term set owner, or are able to add new terms. Use the Managed Metadata column type when you wish to provide users with a choice of tags from a given term set in the term store.
Enterprise Keywords	A special column type added to a list when users enable Enterprise Keywords in the Enterprise Keywords and Metadata Settings section of the List Settings page. Terms entered by users in Enterprise Keywords columns appear under the System/Keywords node in the term store. Use the Enterprise Keywords column type when you want to allow users to tag with their own tag values.

After your browser posts back to display available properties for the selected column type, scroll to the section on Term Set Settings, as shown in Figure 1.

Figure 1. Term Set Settings in the Create New Site Column page

The Term Set Settings section includes the option to bind the new Managed Metadata column to a particular term set in the term store. In Figure 1, I created a simple group called Food and a term set called Fruits.

If the term set has an open policy, users can add new terms to the set from the column user interface. If the administrator specified the feedback e-mail address, then users also have the option to suggest terms via a feedback e-mail, which appears at the top of term selection dialogs.

Owners of a site column can choose to create a customized term set rather than use an existing term set in the term store, which then creates a term set in the Managed Metadata Service Term Store.

Note  If SharePoint displays an error message that there is no default term store associated with the site, ensure that you check the check box for default term store, as in Figure 2 earlier.

The Enterprise Keywords column type is a special SharePoint column type. The following steps demonstrate how to enable Enterprise Keywords on a list:

1. From a list page, click the List/Library tab on the ribbon.
2. Click the List/Library Settings icon.
3. Click the Enterprise Keywords and Metadata Settings link.
4. Enable the Enterprise Keywords option.
5. Return to the List/Library Settings page; you should see a new Enterprise Keywords column added to the list columns definition (Figure 2).

Note  You cannot create a new site column of Enterprise Keyword type. They apply only at the list/library level.

In the next section, you will see how both Enterprise Keywords and Managed Metadata columns appear to end users in the SharePoint site user interface.
