The overall structure of the CINDI system is shown in Figure 1.
The user interface for the CINDI system consists of three graphical interfaces: the SH index registration system, the search system, and the annotation systems.
These values are stored in the CINDI database and are associated with all SHs registered using this pair of values.
In the event a resource provider has a basic idea of a term in the subject hierarchy that she or he wants to use as a resource, the term could be entered in the search slot of the GUI and use the synonym substring feature to query CINDI for a controlled term.
The index entries registered by a provider of a resource in CINDI are stored in SHDDB.
The database on different subjects in the CINDI system is to be maintained at different sites of the communication network (as illustrated in Figure 1).
The REGISTER push button allows providers to register the current semantic header into the CINDI database.
The CINDI system offers a wide range of search criteria to allow precisely targeted resource retrieval.
The second counter indicates the number of accesses made via CINDI to the actual resource corresponding to a semantic header.
The distribution of the rules in CINDI improved performance since only a small number of rules had to be developed in such an environment.
With the newer tools, such as XML and Java, we have undertaken porting CINDI to the Web.
