Sharing contextual information in a machine-understandable way.

Semantics provide context to raw data

Metadata is "data [information] that provides information about other data“

Semantic metadata, i.e metadata that is defined using shared conceptualisations (ontologies)

e.G GS1 Standard

Semantic metadata

Without meaning, a time-consuming manual normalization effort is needed

OPC UA as framework

Address Space = set of objects that the OPCUA server makes available to clients

data available in a structured way, things become self describing

no normalization

OPC UA Companion specifications

16/10/2018 8

OPC is the “HOW”

Companion specifications are the “WHAT”

describe the product and itsfeatures (terms and content)

by all manufacturers in thesame way

companion specifications have to be described bymanufacturers => workinggroups by application

Challenges

CNC controllers, monitoring system are most of the time not OPC UA compliant

The semantics of the existing standards don’tfulfill all our use cases : specific information modelling

Installed OPC UA servers don’t provide the option to adapt information models in them

Conclusion

16/10/2018 16

OPC UA offers the framework to exchange well-defined information

Today OPC UA represents a huge step towards Intelligent machines…

Information modelling is a challenge, but it is an efficient way to make the data actionable

It is time to take full use of it!
