EIP-AHA: Towards Platform interoperability – part I & II
Participants: Antonio Kung, TRIALOG; Danny Lousberg, Technicolor; Keith Baker, Philips; Omar Elloumi, Alcatel-
Lucent; Peter Wintlev-Jensen, European Commission; Reiner Wichert, Fraunhofer AAL; Rob Ekkel, Philips; Saied
Tazari, Fraunhofer IGD
As the EIP-AHA and the Technical Working Group of the IEC System Committee AAL are working towards
interoperability between open platforms and their components, this session seeks to provide participants with insights
based on the viewpoint from the user perspective as well as from the technical bottom up approach.
SUMMARY
The first session focused on requirements. Presentations were made by
 Philips (Keith Baker) on the needs for an unified IoT to project services to the home, based on unified IP.
 the European Commission (Peter Wintlev) on the need to have IoT based Open Service platforms and to
develop matching interoperability profiles, necessitating further initiatives on specifications, standards,
certification. Peter Wintlev also highlighted (1) the upcoming H2020 calls that emphasize the usage of existing
open platforms as well as (2) the cross-community approach in IoT-1 to IoT-3 calls towards global standards.
 Fraunhofer IGD (Reiner Wichert) on the IEC System Committee AAL (IEC SyC AAL), in particular WG2 on
architecture and interoperability which will in particular focus on semantic communication solutions and inter-
platforms interoperability.
The second session focuses on platforms. Presentations were made by
 The chair (Antonio Kung) on the common layer model view (application layer, service layer, network layer) and
need to federate platforms
 Technicolor (Danny Lousberg) who presented the Allseen alliance (a Linux Foundation collaborative
project for open source IoT software) and the Alljoyn platform
 Alcatel-Lucent (Omar Melloumi) on the OneM2M archtiecture and the support of cross platform exchange
 Philips (Rob Ekker) on the CRYSTAL on Seamless Life-Cycle Collaboration for
Safety-Critical Systems Engineering (focusing on interoperability between system development tooling)
 Eurescom (Anastasius Gavras) on the FIWARE platform and its domain specific instance for eHealth (FI-
STAR) including the concepts of generic and domain specific enablers
 Fraunhofer IGD (Saied Tazari) introduced universAAL, the open platform promoted within the AAL and EIP-
AHA communities, highlighting its status, its support for semantic interoperability and its connection to the
general IoT scene.
Discussions took place with the audience on various aspects such as scalability, liability, improving quality of service,
and privacy. It was agreed that the vision of many applications on top of billions of devices could not happen with one
single platform. It necessitates a set of cooperating platforms. Two interoperability needs where discussed:
 semantic interoperability between 2 applications. Three barriers were mentioned, (1) convincing business
rationale, (2) training on the practice of semantic interoperability and (3) consensus building on interoperability
specifications
 platform interoperability between applications and platforms (allowing applications to use features from
different platforms). The barrier of interplatform interoperability was mentioned.
Participant agreed on the interest to continue discussions in order to progress on the issues of platform interoperability.
Platform interoperability could be addressed in a more targeted way in a joint undertaking in the context of IoT-3, using
also first experiences from the large-scale pilots of the IoT-1 call
