The Problem

• Methods to properly

analyze and model

occupants behavior.

• DNAS (Driver-Need-

Action-System)

Framework.

• The obXML schema

to represent

occupants behaviors

and systems

The Problem

• However obXML is not an

ontology: Not semantic

nor ontological format !

• Other drawbacks:

• Lack of integration with

other building related

domains.

Conclusions and Future Works

21

• The conceptualization of an ontology do not follow

hard coded rules.

• Reutilization of ontologies is costly, both in

understand the original model and adapting it to our

conceptualization.

Conclusions


Conclusions and Future Works

22

• Use of test verification techniques Unit tests.

• Evaluation of real use cases from pilot sites. Relate

occupancy profiles with space materials or geometric

information?

• Modulatization of the ontology, dividing it by levels of

complexity, like the OPM ontology.

• Explore the construction of RML mappings to

transform obXML data into RDF triples automatically.

• Review of additional aligments with other ontologies.

Future Works
