Extensibility and integration layers

Prev Next

The Grassfish platform is deliberately designed so that the core remains stable and customer-specific logic is added via extension points.

UDC

The Universal Data Importer (UDC) is used to interpret and distribute data within the system. It enables the import of data from external sources, such as a product database or weather forecast information. The data sources are managed centrally in the content management system (CMS), and the imported data is embedded in spots.

UDC is a plugin-based framework for data imports and system integrations:

  • Flexible data sources: UDC supports connections to REST APIs, SOAP services, and file-based sources (CSV, JSON, XML, etc.).

  • Mapping and transformation: Incoming data can be mapped and transformed to match the internal data model.

  • Extensible via plugins: New integrations are added as UDC plugins, no changes to the core application are required.

Reporting Gateway

The Reporting Gateway provides a modular, plugin-driven architecture for reporting and analysis.

  • Plugin-based reports: Reports, exports, and specialized analytics are implemented as individual plugins.

  • Customizable without core changes: Customer-specific reporting requirements can be fulfilled without modifying the core platform or affecting system stability.

Spots and dynamic content

Spots (HTML-based content blocks) can dynamically load external data at runtime.

  • Runtime data loading: Content can fetch data via HTTP(S) during playback.

  • Flexible authentication: API keys, tokens, OAuth2, and other authentication methods can be configured per location or deployment.

  • Dynamic content: Enables data-driven, context-aware content without requiring changes to the core CMS.

Player add-ons and standalone services

The player supports extensibility through add-ons and optional standalone services.

  • Player add-ons: Additional functions or protocols (e.g., sensors, hardware integrations) can be implemented as modular add-ons.

  • Standalone cluster services: For complex or mission-critical integrations, dedicated web services can run within the cluster, acting as adapters or proxy services.
