the modeling of the functional dependencies between objects and the functions of
objects and also use of metadata. These should include representation of the quality
of individual information pieces (metadata at the levels of objects, attributes),
lineage, acquisition methods, accuracy, age, and propagation of quality data for
aggregations and other types of computations (L

).
While the changing of standardized technologies is a complex process based on
a broad consensus and compromises, updates of the Building Documentation
System data model are implemented in a simpler and faster way. Regarding the
development of the Building Passport, besides updating data due to renovations and
other adjustments, updates are also made to acquisition data from buildings under
construction (new buildings of the Faculty of Informatics or the Faculty of Arts). It
is being planned to create 3D geometry in LoD 2 for each building owned or used
by Masaryk University.
Even greater use of data maintained for operating activities, property records,
and facility management is assumed (e.g. there are requirements for determining
the number of windows for cleaning). This includes the area of space management
for maintaining, updating and displaying data relating to the use of Masaryk
university
s space, where a building or part thereof is used by external entities.
Finally, there should be greater integration with the Information System of
Masaryk University (IS MU) and with other existing spatial data (indoor spherical
images, thermal images of facades) to provide data from the Building Passport for
study purposes and research activities. In this area, an advanced application for
navigation will be implemented. This navigation will not simply search for the
shortest route, but should also take account of the user
'
s context. Thus, for example,
if the building has an access control system, navigation will be addressed with
regard to whether the user has access rights to the room. Navigation can also be
adapted to the needs of disabled users

Conclusions
This article presents the issues relating to the re-use of a Building Information
Model (BIM) in the form of 3D models and visualizations. One of the main
motivations for this re-use is the value of data acquisition needed to establish
a BIM. Re-use of a BIM in the form of 3D models and visualizations opens
the door to various fields of study, such as architecture, engineering, or spatial
planning. We may also perceive these models as a foundation stone for a 3D
cadastre supporting decision making processes within and beyond public
administration. 3D models and visualizations based on spatial data from
BIM are also closely connected to existing standardization activities. The
implementation specification of the Open Geospatial Consortium (OGC)
called CityGML enables the handling of BIM spatial data. Feedback on
CityGML was given to the OGC to support progress in the standardization
of CityGML. The authors of this paper have recommended correcting
