Internet of Things (IoT)

katya: Will discuss what we're doing. Started project 2.5 years ago, continuing until the end of this year.
... Some of our approaches are more generally applicable than only IOT.
... Multiple platforms, using different stnadards.
... Semantics of data differ. Problems accessing them and exchanging data.
... Two use cases: Transport and logistics; and eHealth/mHealth
... We approach interoperability at all levels.
... On data and semantics layer, we have a component: Inter-platform semantic mediator (IPSM)
... Transforms RDF graphs. Based on translation channels -- pub/sub paradigm
... Preliminary "lifting" step are done by producer and consumer.
... We align to/from central ontology.
... We assume central ontology to be used. Generic Ont of IOT Platforms, used for central ont in IOT domain.
... Has basic concepts limited to general IOT concepts.
... Estension of Generic Ont for IOT platform (GOIoTPex) for each domain, such as healthcare.
... Central ont was designed to be extended.
... Core concepts include User, Service, Platform, Device, Location, Unit, Observation
... Inter-Platform Semantic Mediator is not restricted to IOT.
... It's a universal RDF translator / graph rewriter.
... Configurable with alignment files. Main use case is for translating small messages.

eric: Can we see the mapping files?

katya: Yes, in a moment.

(katya is back)

katya: we only translate when needed

(skipping to example)

pawel: Alignment API, file is in XML.
... Level 2 is mapping of complex expressions, which we do.
... source and target RDF patterns show what you want your graph to match, and its
... rewritten into the other.
... Patterns are similar to RDF but they have variables.

katya: considering FHIR ont for use.

pawel: you provide Config files / alignment files only for translations you actually need.
... For example, a module for eHealth domain.
... BodyCloud is from one of our partners, a medical platform. It sends observations, using mobile device as intermediary.
... E.G., CTX is an owl individual, a BodyClouid object. Describes an observation about blood pressure.
... WE have generic observation in central ont, but not BP.
... We rewrite RDF graphs configured by alignment files, that expand the model in which the same info is expressed.

katya: In alignment format, it is quite expressive.

<scribe> ACTION: Katya to send slides

<trackbot> Sorry, but no Tracker is associated with this channel.
