- Administering
  Use the administration tools that are provided with the HCL Digital Experience to do various day-to-day administration tasks.
- 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 Digital Experience.
        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.
        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.
        Examine capabilities
        Use the Capabilities section to explore capabilities that are defined as part of modules.
        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 | HCL Digital Experience
        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 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 Portal 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.
