Metadata is "data [information] that provides information about other data“
Semantic metadata, i.e metadata that is defined using shared conceptualisations (ontologies)

OPC UA Information Modeling

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!
