Magnolia stores data in a Java Content Repository. The repository is a hierarchical object database that is particularly well-suited for storing content. In a content management system you need to be able to store text, documents, images and other binary objects along with their metadata. The data is structured as a tree of nodes. Each node can have one or more types. The type defines what kind of properties the node has, the number and type of its child nodes, and its behavior. See Jackrabbit Node Types for more information and Node Type Visualization for a diagram of the node type hierarchy.
In Magnolia we define custom node types that define Magnolia's custom content model. The JCR in turn enforces the constraints of that model at the repository level. If you need to reference JCR node types in your code, Jackrabbit's JcrConstants is useful. We provide constants also for Magnolia's custom node types but also convenience methods. For example, to update the last modification date of a node, use the NodeTypes.LastModified.update(node) convenience method. Magnolia node types are registered by the
$webResourceManager.requireResource("info.magnolia.sys.confluence.artifact-info-plugin:javadoc-resource-macro-resources")
NodeTypes
Java class.
Prefixes
Node type | Prefix | Notes |
|---|
JCR primary node type | nt:
|
|
Mixin node type | mix:
|
|
Magnolia node type | mgnl:
| The mgnl prefix does not tell you whether the node is a primary node or a mixin. To find out which type a mgnl node is, check the
magnolia-types.xml
file. |
Node type hierarchy
. For example, mgnl:page extends mgnl:versionable. This means that page is an object you can version. In contrast, mgnl:area and mgnl:component are not versionable – they are subnodes that must be activated together with the parent page. However, all three node types (page, area, component) are renderable which means you can render a component on its own without its parent page. See the
magnolia-types.xml
file for a full view of the Magnolia node type hierarchy.
Primary node types
Every node has a primary node type assigned to it upon creation. The primary node type defines node structure such as allowed and required child nodes and properties. Primary types reflect the business that is represented in the repository. Magnolia's primary node types define content management nodes such as pages, areas, components and resources.
JCR primary node types
Notation | Description |
|---|
nt:base
| The base type of all primary node types. |
nt:unstructured
| Unstructured node type that allows any properties and child nodes. |
nt:hierarchyNode
| Abstract base type for nodes in a structured node hierarchy. |
nt:file
| JCR representation of a file. |
nt:frozenNode
| This node type is used in the versioning system. |

These types are required for the basic features of Magnolia to function: configuration, page-editing and rendering as well as activation from author to public (which relies on versioning).
Notation | Description |
|---|
mgnl:area
| Area |
mgnl:component
| Component |
mgnl:content
| Activatable and versionable content objects such as pages. |
mgnl:contentNode
| Activatable but not versionable content objects which can be rendered independently. For example, blocks or objects below page level such as such as area or component. |
mgnl:folder
| Folder |
mgnl:group
| Group |
mgnl:metaData
| Metadata |
mgnl:nodeData
| Property |
mgnl:page
| Page |
mgnl:reserve
| Reserved for system use. |
mgnl:resource
| Resource |
mgnl:role | Role |
mgnl:user
| User |
Mixin node types
Mixin node types specify additional properties or characteristics to the node. A node can have a primary type and several mixin types at the same time. JCR mixins add repository-level functionality such as versioning and locking. Magnolia mixins add content management capabilities such as activating and rendering.
JCR mixin node types
Notation | Description |
|---|
mix:referenceable
| Mixin type for referenceable nodes. Provides an auto-created jcr:uuid property that gives the node a unique, referenceable identifier. |
mix:versionable | Mixin type for versionable nodes. |
mix:lockable | Enables locking capabilities for a node. |
Magnolia mixin node types
Notation | Properties | Description |
|---|
mgnl:deleted
| mgnl:deleted (DATE)
mgnl:deletedBy (STRING)
| Date the node was deleted, the user who deleted it and the deletion comment. |
mgnl:lastModified | mgnl:lastModified (DATE)
mgnl:lastModifiedBy (STRING)
| Date the node was last modified and the user who modified it. |
mgnl:activatable | mgnl:lastActivated (DATE)
mgnl:lastActivatedBy (STRING)
mgnl:activationStatus (STRING)
mgnl:lastActivatedVersion (STRING)
| Date the node was activated, the user who activated it, its current activation status and the version in which the node was activated.
Note that on the public instance, lastActionDate always contains the date of the previous activation, not the current one. This is because the lastActionDate is updated only after the content is sent to the public instance. |
mgnl:created | mgnl:created (DATE)
mgnl:createdBy (STRING)
| Date the node was created and the user who created it. |
mgnl:renderable | mgnl:template (STRING) | Associates a template with the node for rendering. |
mgnl:versionable | mgnl:comment (STRING) | Allows the user to leave a comment on the version. |
Same name siblings are not allowed
The Magnolia node type definition
magnolia-types.xml
does not allow same name siblings. . Typically same name siblings is not an issue because Magnolia enforces the constraint automatically during normal usage. However, if prior to Magnolia 5.2 you imported an XML file that was created outside of Magnolia or was edited by hand, it is possible that the XML import created a same name sibling.
Use the siblings.groovy script to find same name siblings in your repository. The example below searches for identically named areas (returnItemType is mgnl:area) in the website workspace under the /travel/about page. See Groovy module for instructions on how to execute Groovy scripts.

def siblings(workspace,path,returnItemType) {
query = "/jcr:root" + path + "//* order by @name"; //i.e. path=/travel/about
try {
NodeIterator nodes = QueryUtil.search(workspace,query,Query.XPATH,returnItemType);
Session session = MgnlContext.getJCRSession(workspace);
def siblings = [];
while (nodes.hasNext()) {
Node node = nodes.nextNode();
nodePath = node.getPath();
if (StringUtils.contains(nodePath,"[")) {
println "found same name sibling of '${node.getName()}' at ${nodePath}";
siblings.add(node);
}
}
siblings.each {
nodePath = node.getPath();
newName = Path.getUniqueLabel(session,nodePath,node.getName());
NodeUtil.renameNode(node,newName);
println "${nodePath} was renamed to ${newName}";
}
session.save();
} catch (Exception e) {
println e;
}
}
//example
siblings("website", "/travel/about", "mgnl:area");
:
workspace: Any Magnolia workspace.path: A valid path in the workspace. / will search for everything under the workspace root.returnItemType: A valid JCR node type. The query goes through all node types but the results are filtered to the node type you specify. Use nt:base as a "wildcard".
Module-specific node types
The following sections list node types that are provided by individual Magnolia modules. You can define several node types per module if you so require. Almost all the node types added inherit from mgnl:contentNode or mgnl:content.

Notation | Description |
|---|
mgnl:category | An object containing a category. Inherits from mgnl:content . |
Content Editor module
Defined in
content-editor-nodetypes.xml
.
Notation | Description |
|---|
mgnl:block | Content editor block objects containing text, image or similar content. Inherits from mgnl:contentNode and are activatable but not versionable. |
mgnl:composition | Compositions are activatable and versionable as a whole and contain ordered subnodes of type mgnl:block. |
