FIRS has a collection of specifications which define the following service elements: Namespace Rules, Schema Definitions, Query-Processing Rules.
The original WHOIS service was intended to be a centralized repository of ARPANET resources and users. Eventually, many Whois resources sprung-up all over the world, only providing information about particular network resources under the control of a specific organization.
There was not a strict set of data-typing or formatting requirements. This resulted in different implementations providing different kinds of information. There were also problems with privacy and security.
Thus, FIRS was bourn out of a need for specifications that cumulatively define a structured and distributed information service, including an extensible framework and resource-specific definitions.
