Query+RegStoredQuery+Research

= This issue is now closed. It is FAQ DocQuery-015. = =Relevance of all 13 IHE specified Registry Stored Queries to Nationwide Health Information Network=

Background
The AdhocQuery protocol includes support for stored queries. Rather than exchange actual query expressions, this transaction makes use of a collection of pre-defined, parameterized stored queries. Each stored query is identified by a Query Name and Query ID and is associated with a specified set of query parameters. The list of standard XDS queries available for this transaction as defined in Section 3.18.4.1.2.4 of ITI TF-2a and is provided below. Find Documents shall be the primary query [proposed]. Nationwide Health Information Network intends that responding Nationwide Health Information Network Gateways shall support all of the stored queries listed, however, some stored queries rely on concepts which may not be supported within an NHIO (IHE community). It is also possible that a Responding Gateway community may have policies which restrict the sharing of information related to those concepts. The concepts of concern are submission sets, folders and associations. In either case, a Responding Gateway shall respond to unsupported stored queries by returning zero results.
