MODEL BASED
Topics to address in the ‚Enterprise‘ space
Framework level related topics
 Life Cycle Management
The control of the complete lifecycle of devices and their respective
services is key
 Device profiling
 Service profiling
 Business Process Modeling ‘Interpretation’
Modeling new business processes needs to result in ‘deployable’
bundles
 Programming model
 Meta Language
 Semantics

Topics to address in the ‚Enterprise‘ space
Framework level related topics
 Supportability, Supportability, Supportability
The remote support of business applications at customer side is one of
the key successors in the enterprise space.
 Remote management, Remote debugging, Remote monitoring, etc.
 Extensibility
SAP applications are customized and extended in almost 100% of all
cases
 Patches, Extensions, Updates, Versioning
 Network connection awareness (general topic)
Many useful functions are only possible if you know more details about
the current state of the connection to the network.
 Network connection state awareness
 Network connection bandwidth awareness
 Connected and offline support

Topics to address in the ‚Enterprise‘ space
Application level related topics
 Data synchronization & data persistence
Enterprise applications often require the availability of data even if the
client is not connected to the network. Those data must retrieved, locally
stored & changes must be synchronized with the backend later on.
 Internationalization
There is no application at SAP which is not available in many languages.
 Connectivity
Beside remote connections to management systems there is a huge
demand to access also remote functionality.
 WebServices, XML-RPC, etc.
 Security
 Security
 Certification of services

Topics to address in the ‚Enterprise‘ space
Application level related topics - other ideas
 User context awareness
Context based services are a perfect example for the adoption of the
dynamic nature of an OSGi-Runtime.
 Where am I? – Location, Who am I? – Identity, etc.
 Integration of user interface technologies
There should be clear way, how an arbitrary UI-Technology could be
integrated into an OSGi-Runtime (without making UI part of OSGi).
 Native UI, Non-Native UI
 Pixel based UI, Vector based UI
