Interoperability Repository System for the Internet-of-Things

The Internet-of-Things is a dynamic global network infrastructure where physical and virtual things communicate and share information amongst themselves. Plug-and-Interoperate is an approach that allows heterogeneous things to plug (into data) and seamlessly exchange information within the environment. To allow that, Plug-and-Interoperate needs to have the comprehension about the existing interoperability information. For this, the interoperability information needs to be duly organized. However, and in the Internet-of-Things, this presents major challenges. First, it is difficult to index all interoperability information due to the things heterogeneity (many and different languages and formats) and due to the dynamics of the system (disparate things entering/leaving the environment at all times). Also, that the environment can be used with much different purposes, which hinders the way on how the interoperability information should be organized. So, an architecture of an Interoperability Repository System is presented, in order to organize all interoperability information in this kind of environments. The solution handles heterogeneous interoperability information and allows users to add a User Space to the repository in order to customize it to specific needs. It also provides a notification mechanism in order to notify users of new or updated interoperability information.
