## External-component-plugin

### Init data configuration

#### Init data

Application | Component | Description
--- | --- | ---
Forum | `KSDataLocation, ForumServiceImpl` | To initialize default data of the Forum portlet.
Answers | `KSDataLocation, AnswerServiceImpl` | To initialize default data of the Answers portlet.
Polls | `KSDataLocation, PollServiceImpl` | To initialize default data of the Polls portlet.

The Init data plug-in is used to define the default data in the .xml file. It includes nodes (node of jcr).

When the component org.exoplatform.services.jcr.config.RepositoryServiceConfiguration is initialized, the component org.exoplatform.services.jcr.impl.config.RepositoryServiceConfigurationPlugin will be get and the function addConfig is called. Then, the /ks-extension/jcr/repository-configuration.xml file is loaded and the component org.exoplatform.ks.common.jcr.KSDataLocation will be initialized. Next, the setLocation function is called, setting up the workspace and repository for KS. After that, the addPlugin function will be run, generating the DataLocation (some parent nodes) for KS.

#### Configuration

##### Initialize the conf-part for loading repository-configuration.xml.

When the server starts, the jcr-configuration.xml file is initialized. The component-plugin named addConfig will be referred to org.exoplatform.services.jcr.impl.config.RepositoryServiceConfigurationPlugin to load the war:/ks-extension/jcr/repository-configuration.xml_ file.

     <component-plugin>
          <!-- The name of the plugin -->
          <name>Sample RepositoryServiceConfiguration Plugin</name>
          <!-- The name of the method to call on the RepositoryServiceConfiguration
               in order to add the RepositoryServiceConfigurations -->
          <set-method>addConfig</set-method>
          <!-- The full qualified name of the RepositoryServiceConfigurationPlugin -->
          <type>org.exoplatform.services.jcr.impl.config.RepositoryServiceConfigurationPlugin</type>
          <init-params>
            <value-param>
              <name>conf-path</name>
              <description>JCR configuration file</description>
              <value>war:/ks-extension/jcr/repository-configuration.xml</value>
            </value-param>
          </init-params>
     </component-plugin>

- In which:

Name | Set-method | Type | Description
RepositoryService ConfigurationPlugin | addConfig | org.exoplatform.services. jcr.impl.config.Repository ServiceConfigurationPlugin | To read configuration of JCR data to initialize data

- Init-params

Name | Possible value | Default value | Description
conf-path | `string` | war:/ks-extension/jcr/ repository- configuration.xml | The path to the repository-configuration.xml file

##### Initialize workspace name and repository name in storage-configuration.xml.

In details:

Once the war:/ks-extension/jcr/repository-configuration.xml_ file has been initialized, the server will load the storage-configuration.xml file, and the setLocation function in the org.exoplatform.ks.common.conf.DataLocationPlugin component will run.

      <external-component-plugins>
        <target-component>org.exoplatform.ks.common.jcr.KSDataLocation</target-component>
        <component-plugin>
          <name>ks.data.location</name>
          <set-method>setLocation</set-method>
          <type>org.exoplatform.ks.common.conf.DataLocationPlugin</type>
          <init-params>
            <value-param>
              <name>repository</name>
              <description>JCR repository for KS data</description>
              <value>repository</value>
            </value-param>
            <value-param>
              <name>workspace</name>
              <description>workspace for KS data</description>
              <value>knowledge</value>
            </value-param>
          </init-params>
        </component-plugin>
      </external-component-plugins>

In which,

Value-param | Possible value | Default value | Description
--- | --- | --- | ---
repository | `string` | `repository` | The JCR repository for KS data.
workspace | `string` | `knowledge` | The workspace for KS data.

##### Initialize data

Once the workspace name and repository name are registered, the server will load org.exoplatform.services.jcr.ext.hierarchy.NodeHierarchyCreator and the addPaths function in org.exoplatform.services.jcr.ext.hierarchy.impl.AddPathPlugin is called. Then, the data location will be built.

    <component-plugin>
      <name>addPaths</name>
      <set-method>addPlugin</set-method>
      <type>org.exoplatform.services.jcr.ext.hierarchy.impl.AddPathPlugin</type>

### Roles Configuration

#### Overview

The roles plug-in component defines roles in eXo Platform 3 Knowledge Forum. This convenient application defines access to a set of functions within the application. Currently, it only defines the person who has the administrator role. Administrators can get access to administration functions. At runtime, the application gets data from the roles plug-in to decide whether the logged user has the administrative role or not.

#### Configuration

The plug-in is configured in the roles-configuration.xml file.

When the user signs in, his or her username, group and membership will be compared with the user roles defined in the .xml file that is provided by the roles plug-in component.

In particular, at runtime of ForumService, the roles plug-in component is called. The role plug-in is configured in the roles-configuration.xml file. The plug-in component named add.role.rules.plugin will be referred to org.exoplatform.ks.common.conf.RoleRulesPlugin to create users for Forum corresponding to users who exist in the organization database. In addition, the list of users who have administration roles are also defined.

     <component-plugin>
          <name>add.role.rules.plugin</name>
          <set-method>addRolePlugin</set-method>
          <type>org.exoplatform.ks.common.conf.RoleRulesPlugin</type>
          <description>add role rules</description>
          <init-params>
            <value-param>
              <name>role</name>
              <description>name of the role</description>
              <value>ADMIN</value>
            </value-param>
            <values-param>
              <name>rules</name>
              <description>rules of the role</description>
              <value>root</value>
              <!--value>admin</value -->
              <!--value>member:/demo</value-->
              <!--value>/forums/admin</value-->
              <!--value>*:/forum/admin</value-->
              <!--value>/platform/administrators</value-->
              <!--value>manager:/platform/users</value-->
              <!--value>*:/somegroup/somesubgroup</value-->
              <!--value>manager:/somegroup/someothergroup</value-->
            </values-param>
          </init-params>
     </component-plugin>

In which:

Name | Set-method | Type | Description
--- | --- | --- | ---
add.role.rules.plugin | addRolePlugin | org.exoplatform.ks. common.conf. RoleRulesPlugin | To add role rules.

- Init-params:

Name | Possible value | Default value | Description
--- | --- | --- | ---
role | `string` | `ADMIN` | The name of role
rules | `string` | `root` | The rules of role

- When the role-configuration.xml file is executed, the administration role (with `ADMIN` value) will be checked and assigned to a matrix of users/groups/memberships defined inside "value" tags as below:

    <value>...</value>

For example:

    ...
                    <value>root</value>
                    <value>john</value>
                    <value>/platform/administrators</value>
    	        <value>member:/VIP</value>
    		<value>validator:/VIP</value>
    ...

In the example above, the default administrators of Forum include root, john, users in /platform/administrators group and users who have member/validator memberships in the VIP group.

When root, john or any users who belong to the /platform/administrators group or users who have member/validator memberships in the VIP group sign in the Forum, he or she will be identified as the default administrator of Forum.

To add or remove the default administrator of the Forum, simply edit the roles-configuration.xml file, add or remove the relevant "value" tags.

    ...
                    <values-param>
                     ...
                    <value>...</value>
                     ...
                    </values-param>
    ...

The default administrators of the Forum can only change their roles by editing in the roles-configuration.xml file.

At runtime, modifications in the roles-configuration.xml file will be read and database will be updated. Normal users of the Forum and default administration will be created correspondingly.

### ProfileProvider Configuration

#### Overview

Forum and FAQ applications are to show some information about posters. The way we retrieve that information is pluggable through the ContactProvider component.

For public internet websites, users can provide personal information, such as personal email address and location. To enable, simply override the ContactProvider component in your configuration.

#### Configuration

Configure the profile-configuration.xml file as shown below:

    <component>
    	<key>org.exoplatform.ks.common.user.ContactProvider</key>
    	<type>org.exoplatform.ks.common.user.DefaultContactProvider</type>
    </component>

#### Using ContactProvider

When you start the Tomcat, the DefaultContactProvider class will be initialized and the OrganizationService component is set within the DefaultContactProvider component.

The DefaultContactProvider class enables you to get user information via the OrganizationService component.

    public CommonContact getCommonContact(String userId) {
    	CommonContact contact = new CommonContact();
    	try {
    		User user = orgService.getUserHandler().findUserByName(userId);
    		UserProfile profile = orgService.getUserProfileHandler().findUserProfileByName(userId);
    		contact.setEmailAddress(user.getEmail());
    		contact.setFirstName(user.getFirstName());
    		contact.setLastName(user.getLastName());
    		if(profile.getUserInfoMap() != null) {
    			contact.setAvatarUrl(profile.getAttribute("user.other-info.avatar.url"));
    			contact.setBirthday(profile.getAttribute("user.bdate"));
    			contact.setCity(profile.getAttribute("user.home-info.postal.city"));
    			contact.setCountry(profile.getAttribute("user.home-info.postal.country"));
    			contact.setGender(profile.getAttribute("user.gender"));
    			contact.setJob(profile.getAttribute("user.jobtitle"));
    			contact.setMobile(profile.getAttribute("user.home-info.telecom.mobile.number"));
    			contact.setPhone(profile.getAttribute("user.business-info.telecom.telephone.number"));
    			contact.setWebSite(profile.getAttribute("user.home-info.online.uri"));
    		}
    	} catch (Exception e) {
    		log.error("Could not retrieve forum user profile for " + userId + ": " ,e);
    	}
    	return contact;
    }

- The information which is get by the user includes:

Name | Type | Description
--- | --- | ---
email | `String` | Email of user.
firstName | `String` | First name of user.
lastName | `String` | Last name of user.

- The information which is get via UserProfile includes:

Attribute | Type | Description
--- | --- | ---
user.other-info.avatar.url | `String` | The path containing the user's avatar.
user.bdate | `String` | The user's birthday
user.home-info.postal.city | `String` | The home city of user.
user.home-info.postal.country | `String` | The home country of user.
user.gender | `String` | The user's gender.
user.jobtitle | `String` | The user's job.
user.home-info.telecom. mobile.number | `String` | The home phone number of user.
user.business-info.telecom. telephone.number | `String` | The mobile number of user.
user.home-info.online.uri | `String` | The individual websites of user.

- You can get the ContactProvider as follows:

    public CommonContact getPersonalContact(String userId) throws Exception {
    	try {
    		if(userId.indexOf(Utils.DELETED) > 0) return new CommonContact();
    		ContactProvider provider = (ContactProvider) PortalContainer.getComponent(ContactProvider.class) ;
    		return provider.getCommonContact(userId);
    	}catch (Exception e) {
    		return new CommonContact();
    	}
    }

### Forum Configuration

#### BBCode Configuration

##### Overview

The BBCode plug-in component defines default BBCode data in the .xml file, including BBCode tags, for example, I, B, U, SIZE, COLOR.

When the BBCode Service runs, it will get values returned from the BBCode plug-in component to initialize default BBCode data.

##### Configuration

###### Default BBCode data

The default BBCode data is configured in the bbcodes-configuration.xml file.

In particular, at runtime of BBCode Service, the BBCode plug-in component is called. Then, the bbcodes-configuration.xml file will be executed, and the component-plugin named registerBBCodePlugin will be referred to org.exoplatform.ks.bbcode.spi.BBCodePlugin to execute some objects that will generate default data.

In which:

Field name | Value | Description
--- | --- | ---
tagName | `string` | This is the text for the BBCode, which is put between two square brackets ([ ]). For example, for the bold tag, if you type [b], the BBCode tag will be b without any square brackets ([ ]).
replacement | `string` | This is the HTML code that replaces the BBCode entered by the user. Make sure that you include '{param}' (without quotes) to insert the text between opening and closing BBCode tags, and '{option}' for the parameter within the BBCode tag. You can only use option if 'Use Option' is selected.
description | `string` | This is a piece of text to describe the BBCode tag, including HTML tags if you want.
example | `string` | This is a sample piece of BBCode to use as an example for the particular BBCode. For example, to demonstrate the usage of [b] tag, enter [b]text[/b].
isOption | `true`, `false` | To select the [tag=option] [/tag] style tag, rather than just a [tag][/tag]style tag. This function will be created if you select this option.
isActive | `true`, `false` | To activate the BBCode tag.

#### Forums Initializer

##### Overview

The Initialization plug-in component defines the default Forum data in the .xml file, including categories, forums, topics and posts.

When the Forum Service runs, it will get values which are returned from the Initialization plug-in component to initialize default data of the Forum.

##### Configuration

###### Default forum data

The default Forum data is configured in the war:webapp/WEB-INF/conf/ksdemo/ks/services-configuration.xml_ file.

In particular, at runtime of ForumService, the Initialization plug-in component will be called. Next, the services-configuration.xml file is executed. The component-plugin named addInitialDataPlugin will refer to org.exoplatform.forum.service.conf.InitializeForumPlugin to execute some objects to create default data for the Forum application.

##### Overview

The Auto-prune component is to prune inactive topics which have not been viewed, edited or received for a given period. The "prune" operation does not denote to the physical removal of topics, but sets them invisible. The function helps you not clutter busy forums from outdated information.

When the Job Scheduler runs, it will get values returned from the Auto-prune plug-in component to identify topics which have to be inactivated in the Forum application. These topics will be invisible to users.

##### Configuration

The properties of Auto-prune plug-in are configured in the war:webapp/WEB-INF/ks-extension/ks/forum/prune-configuration.xml_ file.
