  - Roadmaps to deploy your system
    Review the roadmaps to understand the common deployment, configuration, migration, and integration patterns.
  - Roadmaps to create your website
    Review the roadmaps to understand how to create your website.
  - Online Help
    This Online Help is made available in the HCL Digital Experience Help Center for quick references on how to install, configure, maintain, and use HCL Digital Experience.
  - Installing
    HCL Digital Experience provides flexible deployment options that range from proof-of-concept where you can examine and test functionality to a highly available and scalable production environment. Review the planning information to learn more about hardware and software requirements, high availability, scalability, supported topologies, and much more. Select your operating system and then select the installation pattern that most reflects your business needs.
  - Configuring
    Run the following tasks after you install and deploy HCL Digital Experience. They address tasks that are typically run one time and have a global effect. Some configuration changes are made more frequently or do not have a global effect. These tasks are addressed in the Administering section.
  - Backup and restore
    Backup and recovery of data files and databases is an essential operation for any business system, particularly for data and applications that run in production environments. Create and follow a plan for backing up and recovering data on all tiers of your HCL Digital Experience deployment. IBM Installation Manager must also be included in backup and recovery planning. If you back up the HCL Portal file structure and then install a fix pack, your HCL Digital Experience and IBM Installation Manager become out of sync after you restore the HCL Portal file system. This condition is not recoverable.
  - Migrating
    Successful migration requires significant planning and preparation, understanding the tools that are involved, and careful execution of the appropriate steps in the order provided.
  - Integrating
    Integrate HCL Digital Experience with software such as HCL Sametime to enable your users to collaborate more easily. You can also use the unified task list portlet to integrate HCL with your backend business process software, such as IBM Process Server.
  - Administering
    Use the administration tools that are provided with the portal to do various day-to-day administration tasks. There are two methods for editing portal setup: using the administration portlets or the XML configuration interface. The administration portlets are a convenient way to make real-time updates to the portal's configuration. While the XML configuration interface is suited to more advanced administration, including batch processing of updates.
  - Securing
    Security tasks include setting up property extension databases and custom user repositories, configuring and activating SSL, and configuring authentication. In addition, tasks such as activating Federal Information Processing Standards (FIPS) and NIST SP800-131a security modules and configuring external security managers such as Security Access Manager might be required to secure your portal environment.
  - Monitoring
    HCL Portal includes tools and features to help you monitor the portal site.
  - Setting up a website
    Setting up a website includes, creating pages, adding navigation, setting up search, and adding content to the site. Themes are used to customize the portal's look-and-feel. Out-of-the-box templates and the site wizard can help you set up your portal site faster. You can add wikis and blogs to your site and let users tag and rate content on your site.
  - Staging to production
    During portal solution development, the solution is initially developed, tested, and refined on one server or a limited number of servers. The solution is deployed later on live systems, referred to as the production environment. The process of moving the solution from the development environment to the production environment is called staging.
  - Developing
    This section includes developer documentation on extending applications and development assets for HCL Portal and HCL Web Content Manager.
    - Changing to a developer mode environment
      Install HCL Digital Experience and then immediately change to a developer mode environment. Use this environment when you develop applications, themes, portals, and portlets. Startup performance is improved within a developer mode environment.
    - Dojo and HCL Digital Experience
      HCL Digital Experience contains an instance of the Dojo Toolkit, a JavaScript library that is based on the Dojo Toolkit. When you develop components that use Dojo, you must be aware of how the portal uses Dojo, and the tips and restrictions when you use Dojo.
    - Extending HCL Portal class path
    - Developing themes and skins
      You can create themes using modules to contribute to separate areas of pages to provide flexibility, enhance the user experience, and maximize performance. To optimize themes on your website, use the theme optimization module framework. The framework separates feature-specific logic and capabilities from the theme code.
      - Roadmap: Creating and customizing themes
        Theme creation and customization are easy when you use the Theme Manager and download your static theme files by using a WebDAV client. This roadmap provides an overview of the theme creation and customization process. Links to detailed instructions for each step are provided in the roadmap.
      - Getting started with Themes
        Before you begin to develop themes, learn about the resources and the tools you can leverage to create and customize them.
      - The module framework
        The module framework allows extensions to contribute to different areas of a page to provide flexibility, enhance the user experience, and maximize performance.
        Basic artifacts and their relation
        The theme modularization framework foresees the following major artifacts and relations to one another.
        Contribution types
        Modules can contribute different types of data to the extension points within the page.
        Deferred and non-deferred modules
        The module framework allows a profile to specify whether to defer a particular module. By default, a module is loaded when the initial page loads, but modules that are specified as deferred modules are loaded after the page loads.
        Resource Aggregator overview
        When the page renders, the Resource Aggregator processes all of the modules coming from the profile.
        Module dependencies in portlets
        When a portlet requires existing client-side capabilities, such as Dojo, loaded on the page, it can define a set of portlet preferences that declare the capabilities it requires.
        Change the auto-loading of portlet capabilities
        You can determine whether portlets automatically load their dependent capabilities for a theme.
        Response rendering for themes
        To decrease the response time of your portal, a template parser resolves which modules are needed and collects all of the modules that are enabled by the current profile. Parts of the content are parsed and displayed as soon as possible.
        Writing modules
        You can define global or theme-specific contributions that contain a theme module, which applies to different scopes through theme profiles. A module defines its contributions by using a plugin.xml or JSON file.
        Theme Optimization Analyzer
        Use the Theme Optimization Analyzer to view, but not edit, all parts of the theme optimization framework inside of HCL Portal. With the portlet, you can easily see which pages have specific profiles that are set or inherited. You can also see which profiles are available and belong to which theme.
        Examine page profiles
        Use Examine Page Profile Information to explore the whole page hierarchy of the system and display information about the set themes and profiles per page. It also differentiates between inherited and explicitly set themes and profiles, and locates errors such as unknown profiles that might be set. It is a great tool to find errors in your deployment.
        Examine modules
        Use the modules sections to explore the modules of a specific profile or all of the modules available with the system, theme, or both.
        Examine contributions
        Use the Contributions section to explore contributions defined as part of modules. You can view the various types of contributions and sub-contributions that are provided and the Reference Identifiers that are provided as part of the sub-contributions within a tree.
        Examine capabilities
        Use the Capabilities section to explore capabilities that are defined as part of modules. You can view the various names and versions in one list, with the modules that exposed them shown.
        Validation reports
        Use the validation portlet to verify that your theme contains no errors. The validation report analyzes your theme and theme components for known issues and reports the number of errors, warnings, and informational messages. It also includes a detailed explanation about how to fix the errors that occur.

        Utilities
        If you need help with a theme issue, you can export your system data. Support personnel can then import and view your data as a simulated system to troubleshoot problems.
        Troubleshooting modular themes
        You can debug your modules to improve performance.
        Specify profiles
        You can specify the profiles that you want to use two different ways depending on whether you are an administrator or a user. Profiles help define which modules are used to render a page.
        Modules that are provided with the modularized theme
        HCL Digital Experience provides a set of ready-to-use modules.
        Modules that add features to a theme
        Theme modules contribute resources, such as JavaScript, CSS and HTML, to a theme or page. The following modules come with the modularized theme and specifically contribute a feature rather than working in the background. The modules can be added to a theme by listing them in the theme's default profile, or to a single page or set of pages.
        Adding or removing a module from a profile
        To add or remove a module, update the profile that is used to render a page for the theme.
        ConfigEngine tasks for creating a new profile based on a template and an existing profile in the system
        You can extend the theme module framework with a new ConfigEngine task.
      - Understanding the Simple Theme
        With the Simple Theme, you can create, copy, and customize themes in minutes with just a few clicks and far fewer files than the Portal 8.5 theme.
      - Understanding the Portal Version 8.5 modularized theme
        Modern websites and browsers enable incredible new capabilities that can greatly enhance your user's web experiences. However, these capabilities are not without cost in terms of large page sizes and more processing in the browser when each page is rendered. These capabilities are worth it when you need them, but removing them for an entire site or including them only on pages that take advantage of these capabilities provides for more flexibility.
      - Customizing the theme
        The module framework allows themes to be customized in order to provide flexibility, enhance the user experience, and maximize performance.
      - Developing themes for a production portal
        Use the theme artifacts to package a theme for staging to production.
      - Device classes
        Device classes are used in HCL Digital Experience as an abstraction for common properties for the device of a client. For instance, tablet computers can be grouped into a device class tablets, since they share a form factor and possibly other traits such as touch interface, or additional hardware sensors.
      - Responsive Web Design
        Responsive Web Design provides content parity between mobile devices and desktop channels, which enhances user experience and brand consistency. Seamless changes in screen size, from small to large, are now possible while the order of the content is maintained. Content maintenance is simplified by having one site that is represented by one set of assets.
    - URL generation in HCL Portal
      Generating Portal URLs correctly is one of the most important tasks in programming an HCL Portal based application. There are several programming tools and techniques available for generating HCL Portal URLs in custom code. The following section introduces the programming tools available and discusses when it is most appropriate to use each of the tools.
    - Model SPI overview
      Models provide information that is needed by HCL Digital Experience to perform tasks such as content aggregation or building navigation to browse the aggregated content. The information that is aggregated is represented through models that can be accessed programmatically by using the Model SPI (read-only). The information of a model is usually persistent (stored in a database) but can also be transient (computed and stored only in memory). Models can be represented by using a tree structure (nodes have a parent-child relationship), a list structure, or a selection structure (a selected element in a tree structure).
    - Controller SPI
      You can use the Controller SPI for portal administration. It allows you to modify portal resources. It enhances the read-only portal Model SPI by adding writable aspects.
    - User and group management
      The Portal User Management Architecture (PUMA) System programming interface (SPI) provides interfaces for accessing the profiles of a portal User or Group.
    - Portal Access Control interfaces
      Portal Access Control provides interfaces for retrieving and modifying and access control information of portal resources, such as portlets or pages.

    - How to create a custom HTML editor integration
      You can use custom HTML editors in all HTML fields of the authoring interface or specific HTML elements that are defined in an authoring template. Custom HTML fields are used to integrate third-party editors into the authoring interface.
    - How to use remote actions
      Remote actions are used to trigger actions from the HCL Web Content Manager application.
    - How to create custom plug-ins
      A custom plug-in is a reusable Java class that you create to run a task. You can create custom plug-ins such as custom workflow actions, plug-ins to run when a page is rendered, plug-ins to store multi-locale text strings and plug-ins to run when a file is uploaded.
    - Digital Data Connector (DDC) for HCL Portal
      You can use the Digital Data Connector (DDC) for HCL Portal framework to integrate data from external data sources on your portal pages by using HCL Web Content Manager presentation components. External data means that the data does not need to be stored directly in HCL Web Content Manager. For example, you can use DDC to render social data that you have on your HCL Connections server or on other social platforms in the context of your portal pages. Other possible data sources include news feeds, task lists, product catalog information, to name just a few.
    - Determining the current web content context
      To determine the current web content context of a portal page or Web Content Viewer portlet, you can use the WCM Page Context Service. This service provides the ID of the currently rendered item of a page or portlet.
    - REST service for Web Content Manager
