Lars Trieloff is a product manager for Day's digital asset management (DAM) system. He discusses how DAM is built on Day's Communiqué platform using Sling, OSGi, and the CRX repository. DAM provides features like rich media handling, extensibility through OSGi bundles, and integration with existing Communiqué applications. Developers can customize DAM by creating new OSGi bundles or using the scripting API.

13. Value Proposition
Unique Repository for Digital Assets
means
reduced cost of ownership for assets
increased value for assets as these are
easily searchable and retrievable
Built-in media processing capabilities
Unlimited Extensibility without
Restarts

15. DAM 4.5?
 Technically, DAM is based on Communiqué 5
platform
 Sling, OSGi, Widget Framework
 But it still integrates with Communiqué 4
 and is made available before CQ5 launch

• Applicable range: getInputMimeTypes(),
getOutputMimeTypes(), canConvert()
• The actual conversion: convert()
• operates at byte or InputStream level

26. Two ways of coding DAM
Take the Volvo or the Vespa
All the power, performance and security of But sometimes all you need is a
Java, static typing, workflows and OSGi quick script around the block...
