A drive is like a shortcut in the content repository, a quick access to some places for users. You can restrict the visibility of this drive to a group/user and apply a specific view depending on the content you have in this area.

For shorter, a drive is the combination of :

org.exoplatform.services.cms.drives.DriveData
name String Name of the drive, must be unique inside WCM
repository String Content Repository where to find the root path
workspace String Workspace in the Content Repository
homePath String

root path in the Content Repository.

 _${userId}_ 

can be used to use the userId at runtime in the path.

permissions String Visibility of the drive based on eXo Rights
example *:/platform/users
icon String url to the icon
views String List of views you want to use
example simple-view,admin-view
viewPreferences Boolean "User Preference" icon will be visible if true
viewNonDocument Boolean Non document types will be visible in the user view if true
viewSideBar Boolean Show/Hide the left bar (with navigation and filters)
showHiddenNode Boolean Hidden nodes will be visible if true
allowCreateFolders Boolean List of nodetype we can create as folders
example nt:folder,nt:unstructured
allowNodeTypesOnTree String Allows you to filter nodetypes in the navigation tree. Default value is "*" to show all content types
example *
exo:taxonomy

We use the following structure for drives configuration

The file that contains the structure above will be configured in configuration.xml file as the following:

Taxonomies are used to sort documents in order to ease searches when browsing documents online. The main idea behind that concept is to provide a multi dimensional set of paths to find a document. The best example is when you browse Yahoo news. In many cases, you can get your content by using different category paths. Therefore, after creating a document somewhere in the repository, it is possible to categorize it by adding several taxonomy references. By browsing the taxonomy tree, it will be possible to find the referencing article and display them as if they were children of the taxonomy nodes. As you can imagine, taxonomies are stored in the JCR itself and we are using the JCR Reference functionality to provide that advanced ECM feature.

Managing the tree of taxonomies is very simple, you can copy/cut nodes and paste them. Of course you can add and remove taxonomies from the tree. Once a taxonomy has been added, any user who has access to the "Manage Categories" icon from his/her view can then browse the taxonomy tree and refer one of its nodes from the created documents.

Every node has a type. A node's type The names, types and other attributes of its child items. Node types can be used to define complex storage objects consisting of multiple sub nodes and properties, possibly many layers deep.

org.exoplatform.services.jcr.core.nodetype.ExtendedNodeTypeManager
name String Name of the Node type, this field is required
isMixin boolean mixin type&nbsp;
hasOrderableChildNodes boolean Orderable childnodes
primaryItemName String Primary item name
suppertype String Name of supper type
propertyDefinition Object Define properties of node type

The node definition should be placed in a special XML file (see DTD below) and declared in the service's configuration file to eXo component plugin mechanism, described as follows:

This is a Nodetype definition file format:

A view can include many object parameters. Parameters are used to create default views, templates and actions of Manage view service. View allow administrators to customize many sort of views that can impact to users in exploring workspace. Each object-param have a type that is a class representing all properties of a view.

org.exoplatform.services.cms.views.ViewConfig

Name Type Description
name String view name, must be unique inside WCM
permissions String Visibility of the view based on eXo Rights
example *:/platform/administrators
template String Specify path to the template location
tabList java.util.ArrayList include a set of view names.

org.exoplatform.services.cms.views.ViewConfig$Tab

Name Type Description
tabName String tab name that is not uniquely
button String These have to specify a set of view component names
example viewNodeType; viewPermissions; viewProperties; showJCRStructure

org.exoplatform.services.cms.views.TemplateConfig

Name Type Description
type String Specify to a name that is truly a class representing all properties of a view.
name String These have to specify a set of view component names
warPath String Specify to a template location for viewing
example /ecm-explorer/SystemView.gtmpl

A template is an definition of presentation while displaying the saved information

Template service is responsibility for select the right template corresponding to the saved content.

Configuration name Data type Default Value Description
autoCreateInNewRepository Boolean true Allow the application automatically import predefined templated at start up of template service
storedLocation String war:/conf/dms-extension/dms/artifacts/templates Location of stored templates
repository String repository Location of stored templates
object-param Structure Configuration for each instance.
Configuration name Data type Default Value Description
name String template.configuration The name of this configuration
description String configuration for the localtion of templates to inject in jcr Description of template instance
object-type Structure Details configuration for each instance type

Object type define all available template file, using the "collection type" configuration

type: name of each object type, it means the type of template, the further configurations for this type are define by the some specify fileds.

Field name Data type Description
nodetypeName String The name of template that is saved as a node in system
documentTemplate Boolean Determine if the node type is a document type
label String Visual displaying of the title for this node

There are 3 further information related to presentation of each template, that is referencedView: Determine how to display to view. referencedDialog: Determine how to display a diaglog to input information. referencedSkin: Determine the style sheet for displaying.

Each type include some definition as an object type="org.exoplatform.services.cms.templates.impl.TemplateConfig$Template"with the fields as the properties.

Field name Data type Desciption
templateFile String The location of the file store for the template's presentation
roles String Determine who can access this object (View/Dialog/CSS)

This bellow example is configuration for the nt:file template, any other template will be put in the same level with this template start from the line <object type="org.exoplatform.services.cms.templates.impl.TemplateConfig$NodeType"> as the another NodeType.
