To optimize themes on your website, use the theme optimization module framework. The framework separates feature-specific logic and capabilities from the theme code.
  - 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.
  - 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.

    You can configure an authoring portlet to use a launch page of your own design instead of the default user interface.
  - 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.
    - Creating a custom button class
      You can create custom button classes that dynamically add custom actions to the authoring interface. Custom buttons are used to integrate third-party tools into the authoring interface without using a custom element. For example, you can use a custom button that adds automatic profiling of a content item or that adds or changes elements on the item forms.
    - How to create a rendering plug-in class
      A rendering plug-in is a reusable class that you create to run a task at render time. It can be referenced within web content by using a plug-in tag. For example, you might write a plug-in that uses attributes from the current user's profile to determine whether the body of the plug-in tag is rendered or not. A rendering plug-in class requires you to reference a set of web content API methods.
    - How to create a custom workflow action class
      You can create custom workflow action classes to add custom workflow actions to a workflow.
    - Creating a Text Provider class
      A text provider is used to provide localized text that can be used within web content item forms. For example, a text provider can be used to localize the field labels or help text within an authoring template so that each user sees the labels or help text in their own language.
    - Creating a Text Provider Factory class
      A text provider factory is used to provide multiple text providers that can be used within web content item forms. Text provider can be used to localize the field labels or help text within an authoring template so that each user sees the labels or help text in their own language. A text provider factory can make multiple such text providers available.
    - Creating a file upload validation class
      A file upload validation plug-in is started anytime a file is uploaded into Web Content Manager. This includes uploading files into file resource, image and stylesheet elements, and images that are uploaded into rich text or HTML elements. The plug-in is called within the "validation" processing that is used by Web Content Manager when uploading files.
    - Creating an item validation plug-in class
      An item validation plug-in is used to validate a TemplatedDocument prior to it being committed to the repository. It is invoked as part of the standard item validation step. For example, saves occurring in the authoring interface, public API or REST API.
    - Creating a subscriber class
      A subscriber plug-in is used to run extra functions on the subscriber that can be used to determine if the subscriber is ready for syndication when a syndication event is started.
    - Creating a syndicator class
      A syndicator plug-in is used to run extra functions on the syndicator when a syndication event is started.
    - Creating a context processor class
      When configured, a context processor plug-in is started by the web content viewer portlet before rendering and allows the current context, such as the item to display, to be modified.
    - Creating an operation check class
      The OperationCheckPlugin plugin is used to control whether an operation within the system should continue or whether it should be stopped. The extension is called prior to committing a Web Content Manager operation to evaluate whether the operation should be allowed to continue. The plug-in can return an error message to be shown to the user.
    - Creating a content page resolution filter class
      A content page resolution filter is used to customize the behavior of the content page resolution filter chain. This method is used to tailor the response to a web content request in several ways, including overriding the content item that is displayed or the portal page that is used to display a content item in the web content viewer.
    - Creating a content URL generation filter class
      A content URL generation filter is used to customize the URLs that are generated by a web content viewer. By creating a plug-in that implements a content URL generation filter, you can tailor the URLs to content items.
    - Deploying custom plug-in applications
      You must deploy your custom plug-in applications on your server before they can be used in your web content system.
  - 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.
