XML schema file, we also defined corresponding attributes with the attributes of
the Storey class.
Through generating and validating the XML schema file, we proposed a
method to implement our data model such as XML schema file and the way to
construct indoor data based on our data model.
As the second step of validation, we created a sample XML document to verify
the expressiveness of our model based on the XML schema. 4-storeys building in
University of Seoul, Korea is a study area for the sample document. Figure

the photo image of the target building.

is a part of a XML sample document. We can describe a storey which
is a set of
interiorRoom
element such as Fig.

.
Finally, we developed a viewer to visualize the XML sample document to vali-
date the expressiveness and correctness of our model which is implemented such
as XML schema. The developed viewer has functions to open and visualize the
sample document and can select each floor to show up.
Figure

is illustrated that opened the XML sample document on the viewer.
As shown in the Figs.
13
and
15
, the XML sample document can represent the
study area almost similar to the reality. Therefore, the CityGML Indoor ADE can
fully represent geometries of indoor space. It means the CityGML Indoor ADE is
an alternative method to represent indoor space and we can construct indoor data
based on the XML schema file.
4.2 Facility Management Using CityGML Indoor ADE
As mentioned as before, the need for indoor space and facility management is
growing and indoor facilities can be used for several application services such
