How will developers create modules of their own? What kind of third-party support will Adobe offer?
Because Adobe Lightroom is being built using an entirely new open modular architecture, third-party vendors will be able to develop modules that plug directly into the Lightroom workflow, and work as first-class citizens with the Adobe-built modules. This will enable developers to deliver valuable enhancements and custom workflows for specialized digital photography requirements. After the final product is released, an SDK for Lightroom will be made available.
