to other types of information systems are missing (town, region, 
republic, tourist industry etc.). 
The results of the analysis of presentation of sites abroad 
brought some interesting information about current trends, see 
chart 2. These trends have the same background. It is — to 
facilitate understanding of the significance of cultural heritage 
to visitors. Complex 3D models of real sites were not included 
in this particular selection. Interactivity was mainly used in 
connection with classical form of data (text, photo). 
2.3 Proposal of conception of spatial IS of historical site 
The proposal of a conception of IS is based on three areas of its 
utilisation. These areas also determine subsystems of IS. 
A complex information system including spatial data should 
comprise subsystems oriented on these areas — site 
management, site research, site presentation. 
Subsystems use the same data set for various purposes. Chart 3 
describes the volume of data for each subsystem.

Chart 3. Subsystems of IS of historical site 
The results of the analytical part of research were the basis for 
definition of principal features of an information system of a 
historical site and its subsystems: 
¢ Subsystem — site management (SM) 
- is intended for management of site, to support decision 
making process 
- user is administration of site 
- system enables - update and editing of data; making 
outputs with use of various types of data; simple spatial 
analysis etc. 
¢ Subsystem — site research (SR) 
- is intended for research of site and its funds 
- users are historians, conservationists, restorers, and 
students 
- system enables — work with other associated systems; 
basic analysis of examined data — e.g. modelling; feedback 
— discussions, publications etc. 
¢ Subsystem — site presentation (SP) 
- is intended for presentation of site 
- user is potential visitor of site 
- System enables — work with virtual reality and 
interaction; work with other associated systems; complete 
service for visitors etc. 
Each subsystem was further specified in three levels, as is 
described in chart 4.

User — a future user has a prime impact on the content and form 
of IS. Users of IS of a historical site are given by area of interest 
(see subsystems). It is naturally possible that they can use other 
subsystems (not only one). 
Data — subsystems have the same set of original data. The 
requirements of subsystems are different and therefore the 
volume and form of accessible data varies, see chart 3. 
Functionality — demands on functionality of the whole IS are 
given by the previous two levels — user and data. Even though 
the subsystems have the same set of basic functions, each 
subsystem also needs a specialised function.

2.3.1 Basic conditions for realisation: Apart from the 
content of IS, fundamental conditions of successful realisation 
and use of IS were defined. These are: 
- utilisation of network technologies, 
- low budget for installation, 
- low cost of hardware and software, 
- simple handling, 
- lucidity, 
- update of data. 
A detailed proposal of technical solution went beyond the topic 
of this stage of the project. One of possible approaches related 
to this theme is e.g. a concept of a distributed system. Data does 
not have to be stored in one central powerful server, but on 
more servers. Utilisation of this concept could be demonstrated 
in conditions of public cultural heritage care (in CZ) on a 
typical relation administration of site «> founder or 
administration of site < network (or fund) administrator. Chart 
5 illustrates this concept.

2.4 “Live Theatre” project 
À concrete project of IS was designed at the end of this stage. 
The main goal was — detailed documentation and elaboration of
