Documentation of GPS and other permanent geodetic sites is increasingly
made available through several media and needs to be available for 
different purposes. As a result, the same information is often available
at different sources. This creates considerable maintenance problems
in keeping all sources up-to-date, thus leading to inconsistencies and   
out-dated information. NMA is developing a structure for a site documentation
with only one primary source of information. This primary source
consists of ASCII files and picture files as master files. From
them, derived information such as log files and web documentation
are created by programs. Whenever information in the primary source 
is changed, semi-automated routines up-date all derived documentation 
as well as all secondary internal and external sources such as 
the IGS data centre.
