 Exchange raw data (bits, frames, packets, messages).
 Well understood and standardized.
 Agnostic.
 Exchange information (data in context).
 Metadata ontology to interpret meaning .
 Standardization attempts (OMG, IPSO, OCF, etc.)
too narrow for cross-industry.
 Domain expertise required.
 Exchange structured data (states, events, streams).
 Standard formats (XML, JSON, etc.).
 Core connectivity standards (DDS, OPC-UA, etc.).
 Cross-industry via standardized gateways.

What is the data type of sensor point?
What is the unit of measure?
What is measured?
When? And where is sensor „zn3-wwfl4“?
Cross-industry semantic interoperability,
Embedded Computing Design June 29, 2017
Device data inconsistent, non-standard naming conventions, limited descriptors!

Normalization?

Cross-industry semantic interoperability,
Embedded Computing Design June 29, 2017
× Standardizing point identifiers
impossible.
× Too much metadata.
× Not extensible. Not changeable.
 Decouple point identifiers from
metadata by association.
 Use domain expertise to build
knowledge base.
 Consistent metadata terminology.
 Use metadata model for mapping.
Normalization? – Metadata Abstraction!
