1. Introduction
This document defines a method to query a reputation data service for
information about an entity, using the HyperText Transfer Protocol
(HTTP) as the transport mechanism and JSON as the payload meta-
format.
The mechanism is a two-stage query:
1. A client retrieves a template from a server that describes the
construction of a Universal Resource Identifier (URI) that will
be the actual query;
2. The client then uses the constructed URI to request the
reputation data from the server.
2. Terminology and Definitions
This section defines terms used in the rest of the document.

document are to be interpreted as described in [KEYWORDS].

2.2. Other Definitions
Other terms of importance in this document are defined in [RFC7070]
and [RFC7071].
3. Description
3.1. Overview
The components to the question being asked are the following:
o The subject of the query;
o The name of the host, or the IP address, at which the reputation
service is available;
o The name of the reputation application, i.e., the context within
which the subject is being evaluated;
o Optionally, names of the specific reputation assertions or
attributes that are being requested.
There is no discovery protocol for finding reputation services.
These are typically subscription services, negotiated between
operators through some out-of-band method.
Assertions are discussed in [RFC7071].
