The general content of this document is specified under the Service Development Framework (SDF) process under the auspices of the Healthcare Services Specification Project (HSSP). Readers of this document should keep in mind that the SFM provides a Service interface specification, not a specification of a Service implementation. (A more detailed contextual discussion of this point is given in the Overview section of this document.) The distinction between a service interface specification and a service implementation is a critical point of distinction in context of Service Oriented Architecture (SOA) methodologies and implementations. In particular, a single service interface specification can - an often does - have more than one associated service implementation, i.e., there are different, semantically consistent ways of implementing all or part of the functionality specified in the SFM and therefore to support the behavior described in this SFM/specification.

The Clinical Research Filtered Query (CRFQ) service is one of several 'business-level' services which are anticipated to utilize other HSSP 'infrastructure' and 'process' services (e.g. RLUS, DSS, Consent, Anonymization, etc.) in business-process-driven orchestrations designed to achieve critical business goals in an automated/semi-automated fashion.

Readers may want to target to review of this document based on their perspective of the CRFQ service. The document provides a high-level guide for readers based on their association with:

• the Regulated Clinical Research Information Management Technical Committee or other organizations, groups, or committees consisting primarily of Subject Matter Experts (SMEs);
• architecture- or design-level groups such as HL7SOA or HSSP; and/or
• responders to the OMG RFP that will be issued once the CRFQ becomes an ANSI Draft Standard for Trial Use (DSTU) through the HL7-supervised ANSI balloting process, as well as other institutions or organizations that may be interested in building initial implementation of the CRFQ service independent of the OMG RFP process.
