\chapter{The QUIPU Pilot DIT}
Table~\ref{pilot:root} show the number of registered QUIPU DSAs at the top two
levels in the DIT as of 
%%%\today.
February~$5^{\underline{th}}$~1991.
The number of entries is an estimation of the number of entries held by 
the DSAs in those countires.  As not all DSA were contactable when the figures
were calculated, this is almost certainly an underestimate.
As the table shows, the QUIPU pilot is now active in 13 countries,
with 177 DSAs, holding data about 370 organisations.
Bearing in mind these figures only take account of DSAs at the top two 
levels of the DIT, and several DSAs are known to be represented lower down
in the tree, we can estimate that there are about 200 DSAs in all holding
close to 400~000 entries.

As an example of the typical spread of data, Table~\ref{pilot:gb} shows the 
organisations participating in the United Kingdom pilot.  The size figure
is only an estimate, and based on the information held by the relative DSAs.
