The Sitecore Content Serialization (SCS) system serializes content items in and out of a Sitecore instance using YAML files1. When deploying to XM Cloud, the XM Cloud deploy process uses serialized item batches through REST APIs at the XM Cloud CM to speed up serialization2. This way, you can serialize large amounts of content items without affecting the performance of the Content Management (CM) instance2.

Sitecore Content Serialization in XM Cloud

According to the Sitecore XM Cloud Documentation for Developers1, a data source item is a content item that provides the content for a component. A data source item can have fields, such as text, image, or link, that can be edited by the content author in the XM Cloud Pages editor. To create a new component that displays content from a data source item, you need to follow these steps2:

Create or reuse a SXA Module, which is a folder that contains the renderings, data templates, and media items for your components.

Insert a new rendering item in the SXA Module, which defines the metadata and parameters for your component. You can also clone an existing rendering item that uses a data source item and modify it as needed.

Use the JSS CLI to scaffold out a new React component in your Next.js application, which defines the layout, style, and logic for your component. You can also copy and paste an existing React component that uses a data source item and modify it as needed.

Register the React component in the Components builder and add it to the Components library.

In the XM Cloud Pages editor, drag and drop the component to the page and select or create a data source item for the component. You can also edit the data source item's fields in the Properties panel.

According to the Sitecore XM Cloud Documentation for Developers1, a placeholder is a named location on a page where components can be inserted. A placeholder can have one or more components assigned to it, and the content author can add, remove, or reorder the components in the XM Cloud Pages editor. To create a placeholder for a page, you need to follow these steps2:

In the Content Editor, create or select a rendering item that defines the metadata and parameters for your component.

In the rendering item, in the Data section, in the Layout field, enter the HTML markup for your component. Include a placeholder tag with a unique name, such as <sc-placeholder key='my-placeholder' />.

In the Content Editor, create or select a placeholder settings item that defines the allowed components for your placeholder. You can also clone an existing placeholder settings item and modify it as needed.

In the placeholder settings item, in the Data section, in the Key field, enter the same name as the placeholder tag, such as my-placeholder.

In the placeholder settings item, in the Data section, in the Allowed Controls field, select the components that you want to allow in the placeholder. You can also use the Edit button to open the Allowed Controls dialog box and select the components from a tree view.

Register the component and the placeholder settings in the Components builder and add them to the Components library.

In the XM Cloud Pages editor, drag and drop the component to the page and use the placeholder to insert other components as needed.

According to the Sitecore XM Cloud Documentation for Developers1, the Security Editor is a tool that allows you to assign access rights to your security accounts, such as users and roles. You can grant or deny the following access rights to individual items in the content tree2:

Write -- grants or denies the right to edit the item and its fields.

Read -- grants or denies the right to view the item and its fields.

Inheritance -- grants or denies the right to inherit the access rights from the parent item.

The other access rights, such as Debug, Access, Rename, Create, Delete, and Administer, are not available in the Security Editor, but can be assigned using other tools, such as the Access Viewer or the User Manager13.

The default scope for a serialization in Sitecore Content Serialization (SCS) includes all the content items under the specified path and all their descendants1. You can configure what and how content items are included and excluded from serialization in a module file such as Project.module.json1. You can also use rules to configure the serialization of content item trees with different scopes1.
