This wiki page will facilitate the capturing of information related to standards and models that can be potentially reused for the purposes of Query Health. The standards referenced here will be used in addition to the Summer Concert Series Patterns and re-usable components.

Existing Standards and their potential applicability to Query Health:
The section will document the various emerging standards that could potentially be used by Query Health in combination with the Summer Concert Series Patterns. The following is an initial list of suggested items by the Technical WG; These items need to be explored and documented for the purposes of Query Health with a focus on how it applies to the Query Health Initiative. The spreadsheet below captures applicable standards, including standards for queries and the representation of query results, terminology standards, standards for the transport and security of queries, and possible clinical models.
 * IHE Emerging Standards related to population health
 * HL7 Emerging Standards related to population health
 * Transition of Care Information Models and Implementation
 * Stan Huff's Clinical Element Model (This was also factored into the Transition of Care Initiative)
 * Sharp-S NLP Work

Linked Data strategy was successfully implemented by CMS to publish the "Hospital Compare" raw data as Linked Data. Users of this data can query this Linked Data using the industry standard SPARQL queries in the form of Restful web servies and retrieve the data in various representations such as JSON, ATOM etc. For more clarity, see the presentation on this project at []
 * Linked Data approach**

This approach is a better scalable approach compared to traditional federated query approaches and also this approach will lead to the creation of "Linked Health Data Cloud", which will promote innovative ways to query this data cloud. But this is entirely a new paradigm compared to traditional techniques discussed/used so far. The steps involved in this approach are:
 * Create (or reuse existing HL7 ontologies) standard vocabulary/ontologies (RDFS or OWL representation) to represent Clinical data (to be done by QueryHealth team) and deliver these ontologies to healthcare organizations
 * Encourage the healthcare organizations to publish their Clinical Quality Data as Linked Data using these standard vocabulary/ontologies. One can use Jena (a Java based framework) transformation engine to transform clinical data to triple graphs. Later these triple graphs can be published as Linked Data by healthcare organizations
 * Once the clinical data is published as Linked Data then it can become part of the "Linked Health Data Cloud", which is an ideal platform to run the distributed SPARQL queries (also see this white paper: [])

The proposed Linked Data architecture is shown below:
