Topics to address in the ‚Enterprise‘ space

  • Framework level related topics

  • Life Cycle ManagementThe 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, SupportabilityThe 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.

  • ExtensibilitySAP 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 persistenceEnterprise 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.

  • InternationalizationThere is no application at SAP which is not available in many languages.

  • ConnectivityBeside 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 technologiesThere 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

  • Steps for deploying a service

  • Development ToolsDesign Time → Application Model

  • System MonitorDeliver status of system landscape

  • Service MapperMap service requirements to current status of system landscape. Where should which service be deployed?

  • Service InjectorInject services into a subset of wireless nodes according to mapper‘s decision

  • Start the service
