Finally, a View can be any output representation
of information, such as a diagram or it may contain
multiple views, such as a map with several
information visualization layers.
Layers on the right shaded as green represent
stakeholder specific development, maintenance and
evolution related aspects of the system with
examples of supporting tools. For instance, ontology
evolution is supported with version control using
GitHub with wiki as a means for documenting the
rationales for changes in ontology. In order to ease
version control, ontology source is developed using
textual Turtle format.
The proposed framework utilizes two of the
main strengths of linked data technologies. First is
that the evolution of ontologies used by models can
be opened to collaborative work among developers.
Second is that the models themselves can be
extended and tailored for the specific needs of
systems and user views by choice of external
vocabularies and ontologies.
4 CONCLUSIONS
This paper has provided the detailed technical
description of a model based approach aiming at
achieving Situation Awareness and support for
decision making in a dynamic medical emergency
response context. The effective exploitation of
domain models, architectural tactics, linked open
data technology and domain specific vocabularies
aim at the interoperability, better acceptance and
evolution of the developed system. The use of Web
standards and a common data model makes it
possible to implement applications that operate over
the complete integrated data space. The focus of our
future work is put on further prototyping of the
proposed SA framework. The developed decision
support services are based on the mathematical
modelling of optimization problems for timely
allocation of resources and on semantically
supported domain knowledge modelling, as well as
on the machine-learning-based prediction of
emergency incident expected victims and
subsequently demand for resources.
