3.3 - Installing an Infostructure on an HTTP Server

Having run WebLinker on an infostructure, we are left with:

an infostructure with updated physical references to external infostructures
a logical to physical Fragment-Id mapping table.

With these, we can now install the structure onto the server. We use a script that will do the dynamic logical to physical conversion. Only one script is needed for all the infostructures stored on a server. The only thing that needs to be added to the server configuration file is one line giving an Exec rule.

Suppose we wish to set it up on www.cern.ch in the directory /www/info, where /www is the root of the WWW Server (See Figure 3). Then we must add a rule to the Daemon configuration file; example is for CERN HTTPD [6]:

Exec    /lrn/*                 /www/lrn/nph-decode/*

where nph-decode is the decode script. Then, using our FARMING infostructure as an example, copy the internal mappings table to

/www/lrn/FARMING.

Now all references to the infostructure, e.g.

http://www.cern.ch/lrn/FARMING#Pigs

will result in the correct HTML document being returned.
