The vCloud Connector Content Library is a library of published folders or catalogs of templates to which users can subscribe. These templates can be virtual machine templates from vSphere clouds or vApp templates from vCloud Director clouds or public vCloud Director-based clouds.

Any user of a vCloud Connector instance can publish a folder or catalog of templates to the Content Library and any user can subscribe to a published folder or catalog.

When a user subscribes to a folder or catalog, vCloud Connector copies the templates from the published folder to the user's subscription folder. Templates are copied in the following way.

Virtual machine templates from a published vSphere folder are copied as virtual machine templates to a subscription folder on vSphere and as vApp templates to a subscription catalog on vCloud Director.

vApp templates from a published vCloud Director catalog are copied as vApp templates to a subscription catalog on vCloud Director. If the vApp template is a single-VM vApp template, it is copied as a VM to a subscription folder on vSphere; if the vApp template is a multi-VM vApp template, it is copied as a vApp to a subscription folder on vSphere.

Subsequently, any changes in the published folder are reflected automatically in the subscription folders.

If a template is added to the published folder or catalog, it is added to the subscription folders and catalogs.

If a template is modified in the published folder or catalog, the modified template replaces the template in the subscription folders and catalogs. (The modified template is copied over with a timestamp appended to its name, then the original template is deleted and the modified template is renamed to the original name.)

If a template is deleted in the published folder or catalog, it is not deleted in the subscription folders and catalogs by default. If you want templates to be deleted, select the Remove entities if deleted at publisher option while subscribing to the published folder or catalog.

Subscription folders are automatically synchronized with published folders at the interval or time specified when the subscription is set up. You can also synchronize the folders at any time with the Sync now option.

The following terms are used in the context of a Content Library.

Published Folder: A vSphere folder or vCloud Director catalog containing templates that has been published to the Content Library. Any user can publish a folder or catalog. A Published icon (published folder icon) identifies published folders in the Browser panel.

Subscription Folder: The destination folder or catalog that you specify when you subscribe to a Published Folder. Templates from the published folder are copied to the subscription folder. A Subscribed icon (subscribed folder icon) identifies subscription folders in the Browser panel.

Polling Interval: The frequency at which your subscription folder is automatically synchronized with the published folder. You can specify either an interval in hours or a custom schedule of specific days and times for the synchronization.
