Sharepoint 2013 : Content Model and Managed Metadata - Publishing, Un-publishing, and Republishing

Publishing, Un-publishing, and Republishing

The creation of a content type for the publication in the content type hub is identical to that to create satisfied seize a collection of site of non-hub. However, when an administrator of collection of site creates satisfied seize the hub, SharePoint present of the additional options of configuration in the Content Type Settings . Once you achieved the stages in the preceding section to indicate a satisfied type hub, the following stages show to create a new content type for the publication with another collection with site with subscriber.

1. Open the Content Type Hub Site Collection.
2. Navigate to the Content Type Gallery from the Site Collections Settings page.
3. Click the Create link at the top of the page to create a new content type.
4. Give the new content type a name, description, and parent and save it.
5. I created a simple content type and inherited from the standard Item content type.
6. Navigate to the Content Type Settings page, like that in Figure 2.

7. Click the link to Manage publishing for this content type.
8. The next page shows three options: Publish, Un-publish, and Re-publish (update).
9. Choose Publish and click the OK button.

   Note  If you receive an error about an incorrect proxy at this stage, then either your site collection hub in the Managed Metadata Service is incorrect (if it is a root site collection, use the / on the end of the URL), or you need to change the URL using the following PowerShell command:Set-SPMetadataServiceApplication "Managed Metadata Service" –HubUri  http://site_collection_hub

10. From the consumer site collection, navigate to the Site Settings page.
11. In the Site Collection Administration section, click the Content Type Publishing link.
12. If you do not see your published content type in the Hubs section, check the error log by clicking the link shown.

Note  By default, the consumer timer job runs every hour and the hub timer job every 15 minutes. The consumer timer job looks after creating and updating shared content types in consumer site collections; the hub timer job notifies consumers of changes to existing shared content types or the existence of new shared content types.

To stop publishing the content type at the hub, continue with the following steps:

1. Navigate to the Content Type Gallery from the Site Settings page of the hub site collection.
2. Select the published content type to view the settings for the content type.
3. Click the Manage Publishing for This Content Type link.
4. Click the Un-publish option and then the OK button.

Note  You cannot delete a published content type. In addition, changes to a content type in the hub do not update the consumers until you republish the content type.

Once a site collection administrator publishes a content type, the timer jobs complete and the content type is available to consumers, who may use the content type as if defined locally. Site collection administrators of the consumer site collection may inherit from the content type or use the content type in the sites and lists of the site collection.

1. Navigate to the Content Type Gallery in the consumer site collection.
2. Scroll to find the Consumed content type in the gallery.
3. Click the name of the Consumed content type to view the Settings page.
4. Click the Advanced Settings link.
5. By default, the Consumed content type is read-only; to allow changes to the Consumed content type, change the read-only setting.

The Error Log

When either the content type syndication consumer or publisher timer job encounters an error, it reports an error in the syndication error log—a list available under the Site Administration section of the Site Collection Site Settings page. Administrators may also access the error log from the link on the Manage Publishing for This Content Type page.

Assuming the administrator did not disable the setting to report syndication errors in the Managed Metadata Service, SharePoint tries to be as verbose as possible in the syndication log. Table 1 depicts the columns in the error log.

Table 1. Columns in the Content Type Syndication Error Log

Column Name	Description
Title	Error title
Taxonomy Service Store ID	GUID of the term store in the Managed Metadata Service
Taxonomy Service Name	Name of the Managed Metadata Service
Content Type Subscriber Site	Link to the consumer site with syndication error
Syndication Item	Content type that failed to synchronize
Syndication Failure Stage	Stage at which the syndication failed
Syndication Failure Message	Specific details about the error
Syndication Failure Time	Timestamp that the error occurred

Sometimes the error log may report no errors and after successful execution of syndication timer jobs, the consumer site collection has no content types from the hub. The following list identifies a few reasons for this that I have encountered during my research:

• The document ID feature is enabled on either hub or consumer but not on the other—this feature must be enabled or disabled on both.
• The Managed Metadata Service proxy is not configured to consume content type publications—enable it from the properties of the Managed Metadata Service.
• I came across one instance in which the consumer failed with an error in the log about unknown site ID. This occurred when I checked the option to consume content types in the properties of the Managed Metadata Service proxy, post creation of the consumer site collection. I remedied the issue by re-creating the site collection, once the Consumer Web Application MMS proxy allowed the content type consuming option.
