A struct property is a specific content field, where you can manage structured data. It is mostly used for some settings of CoreMedia Blueprint.

You can use it, for example, to change the moderation type of a page (see Section 3.3.15, “Configuring Elastic Social”).

Figure 4.60. Struct editor in a Settings content item

You can enter numbers (Integer (4)), text (String, (3)), Boolean values displayed as check boxes (Boolean (2)), links to other CoreMedia content items (Link (5)), dates (Date (1)), passwords, API keys and other secret data (Secret (8)), structured data (Struct (6)), markup and binary content into a struct property.

Note

Creating Secret properties is only possible if a properly configured encryption service is present. If the option is missing, contact your system administrator, who can find information on this topic in the configuration properties part of Chapter 4, Encryption Service Setup in Deployment Manual.

For all types, you can create two different items:

Icon	Name
	Remove item
	Cut item
	Copy
	Paste
	Duplicate
	Move up
	Move down
	Add item
	Add item List property
	Open linked item in tab
	Encrypt string property value

Editing Struct entries

You can change the name of an entry, the value and for a Link the link type. In addition, you can remove items from a list property or from a Struct.

Changing the name

In order to change the name, double-click the Name field and enter the new name. If the new name already exists in the Struct, then it will not be changed.

Changing the value

In order to edit a string or integer value, click the Value field and start typing. For a Boolean value toggle the status by clicking the checkbox.

For a Link value, also click the Value field. The Library opens from where you can drag items onto the drop field. If the Link already contains a linked content, then it will be replaced by the new one. Use the Remove item icon to remove an entry from the Link.

For a Secret value, click the Value field. A dialog opens where you can enter the secret value to be encrypted. Even while entering, charactes are obscured to protect them from observers. Some browsers (e.g. Microsoft Edge) allow to toggle to plain text to check your input. After confirming the dialog, the secret value is encrypted, stored, and from then on displayed as several bullets (•••••••••••••). When hovering over the obscured value with the mouse, you can see that a Secret is actually binary data with a certain media type, so it can be downloaded like any other binary property.

Note

When you click on a Secret's Value field, even if the Secret property already contains a value, the input field in the dialog starts empty, because once encryted, a Secret cannot be decrypted again in Studio. Thus, make sure that any newly generated password is memorized or copied to a safe place before encrypting it, since you will not be able to see it again in plain text, at least not in Studio.

Converting a string to a Secret

If a password or other secret data has already been added as a plain text string property, it can conveniently been encrypted as a Secret property by selecting it and clicking the Encrypt string property value button. The type of the property changes from String to Secret and the value is obscured.

Note

Converting a string to a Secret is only possible if a properly configured encryption service is present. If the option is missing, contact your system administrator, who can find information on this topic in the configuration properties part of Chapter 4, Encryption Service Setup in Deployment Manual.

Changing the link type

The link type of a Link or LinkList defines which content types you can drag into the property. When you create a new Link, you can enter all content items and folders into the property. In order to change the type, click on the dropdown list and select a content type.

If the Link already contains a link which does not fit to the new type, then the link will be removed.

Figure 4.61. Select content type for Link

Cut, Copy and Paste

In order to copy, cut and paste entries, select an entry and use the corresponding icons from the context menu or the toolbar.

When you paste entries, mind the following rules:

Rearrange, duplicate or delete entries

In order to remove, rearrange or duplicate entries select the entry and use the icons of the toolbar or open the context menu with a right-click and select the required option.

With the Remove item icon you remove a property from the Struct editor or a link from a Link. With the Move up and Move down icon you can move items up and down. The Duplicate icon duplicates a complete property and adds it below the one that was duplicated. The Duplicate menu item is especially useful when you want to reuse a Struct property.

Creating new entries

You can add new entries behind an existing entry or inside an existing Struct. Select the entry to which or after which you want to add a new property and select the required type from the split button. A new entry is created below the selected entry if it was not a Struct or otherwise inside the Struct.

Example: Select a Struct and choose String from the split button. This will create a String at the first position inside the Struct.

Creating new list entries

The different list property types are equally handled except for link properties. In order to add entries to a List select the List and click the Add item to List icon. This will create an entry of the required type at the first position of the List. If you want to add entries behind a specific list element, select the element and click again the Add item to List icon. List items have no name but are numbered.

A newly created LinkList looks like a Link (except for the text in the drop area), but you can drag more than one content item to the drop area. So, in order to create entries in a LinkList drag one or more content items from the Library onto the drop field of the LinkList.

Copying complete Struct entry

If you want to copy the content of a Struct property (or any other property), select the Struct property and choose Duplicate from the context menu. This will add a copy below the selected Struct property.

Encrypting Struct string property values

Struct string properties can be encrypted to secure values and hide them from the human eye. In order to encrypt Struct string property values, an encryption service needs to be configured correctly. For configuring an encryption service for this feature, consult the configuration properties setup in Chapter 4, Encryption Service Setup in Deployment Manual.

Upon correct configuration, the encrypt value button in the Struct editor toolbar will be enabled for string properties. Click the button to encrypt the selected string value. Encrypting a string value will change the property type from String to Secret. Encrypted strings are displayed as ******. Once encrypted, the string values are not readable by humans anymore. Services in the background on the other hand, are able to decrypt and use the string values as before. This feature enhances the security of connection secrets, for example. It is appropriate for encrypting Content Hub or Feedback Hub connection configuration secrets.

To change an encrypted value, simply edit the Secret property value and enter the new unencrypted value.
