Then based on the [FHIR RESTful API](http://hl7.org/fhir/search.html), queries are performed to access FHIR resources representing the new Classes or which include the new Data Elements. These resources are then validated against their profile definitions using the [FHIR Validator](http://hl7.org/fhir/validation.html)\n\n*Note:*\n\n1.  *All the variables are collection variables as listed in the Collection folder*\n2.  *the \"patient_id\" variable is assigned after the patient is fetched*\n3.  *the \"base_url\" variable is assigned from the environment if that is empty or undefined it defaults to the HAPI R4 reference server*\n4.  *the \"validator_url\" variable is assigned to Grahame's R4 reference and used to validated the first resource in the search bundle with the $validate operation.*\n5.  *Currently, we do not have a reference implementation that validate all the latest US Core Profiles*\n6.  *Currently. we do not have a reference implementation that supports all the custom search parameters*","schema":"https://schema.getpostman.com/json/collection/v2.0.0/collection.json","isPublicCollection":true,"owner":"1447203","team":111560,"collectionId":"aac9cfd5-9bcf-4ec6-854d-6ed8bcf0add7","publishedId":"UVXgLxNG","public":true,"publicUrl":"https://documenter-api.postman.tech/view/1447203/UVXgLxNG","privateUrl":"https://go.postman.co/documentation/1447203-aac9cfd5-9bcf-4ec6-854d-6ed8bcf0add7","customColor":{"top-bar":"FFFFFF","right-sidebar":"303030","highlight":"EF5B25"},"documentationLayout":"classic-double-column","customisation":null,"version":"8.10.1","publishDate":"2022-01-13T05:04:59.000Z","activeVersionTag":"latest","documentationTheme":"light","metaTags":{},"logos":{}},"statusCode":200},"environments":[],"user":{"authenticated":false,"permissions":{"publish":false}},"run":{"button":{"js":"https://run.pstmn.io/button.js","css":"https://run.pstmn.io/button.css"}},"web":"https://www.getpostman.com/","team":{"logo":"https://res.cloudinary.com/postman/image/upload/t_team_logo_pubdoc/v1/team/af171b781f8e2482f88a15f0b161035637eafc3538f56b60e161bbc73ec58702","favicon":"https://res.cloudinary.com/postman/image/upload/v1608316986/team/qze8hhh2wcfqf0cqkzfw.ico"},"isEnvFetchError":false,"languages":"[{\"key\":\"csharp\",\"label\":\"C#\",\"variant\":\"HttpClient\"},{\"key\":\"csharp\",\"label\":\"C#\",\"variant\":\"RestSharp\"},{\"key\":\"curl\",\"label\":\"cURL\",\"variant\":\"cURL\"},{\"key\":\"dart\",\"label\":\"Dart\",\"variant\":\"http\"},{\"key\":\"go\",\"label\":\"Go\",\"variant\":\"Native\"},{\"key\":\"http\",\"label\":\"HTTP\",\"variant\":\"HTTP\"},{\"key\":\"java\",\"label\":\"Java\",\"variant\":\"OkHttp\"},{\"key\":\"java\",\"label\":\"Java\",\"variant\":\"Unirest\"},{\"key\":\"javascript\",\"label\":\"JavaScript\",\"variant\":\"Fetch\"},{\"key\":\"javascript\",\"label\":\"JavaScript\",\"variant\":\"jQuery\"},{\"key\":\"javascript\",\"label\":\"JavaScript\",\"variant\":\"XHR\"},{\"key\":\"c\",\"label\":\"C\",\"variant\":\"libcurl\"},{\"key\":\"nodejs\",\"label\":\"NodeJs\",\"variant\":\"Axios\"},{\"key\":\"nodejs\",\"label\":\"NodeJs\",\"variant\":\"Native\"},{\"key\":\"nodejs\",\"label\":\"NodeJs\",\"variant\":\"Request\"},{\"key\":\"nodejs\",\"label\":\"NodeJs\",\"variant\":\"Unirest\"},{\"key\":\"objective-c\",\"label\":\"Objective-C\",\"variant\":\"NSURLSession\"},{\"key\":\"ocaml\",\"label\":\"OCaml\",\"variant\":\"Cohttp\"},{\"key\":\"php\",\"label\":\"PHP\",\"variant\":\"cURL\"},{\"key\":\"php\",\"label\":\"PHP\",\"variant\":\"Guzzle\"},{\"key\":\"php\",\"label\":\"PHP\",\"variant\":\"HTTP_Request2\"},{\"key\":\"php\",\"label\":\"PHP\",\"variant\":\"pecl_http\"},{\"key\":\"powershell\",\"label\":\"PowerShell\",\"variant\":\"RestMethod\"},{\"key\":\"python\",\"label\":\"Python\",\"variant\":\"http.client\"},{\"key\":\"python\",\"label\":\"Python\",\"variant\":\"Requests\"},{\"key\":\"r\",\"label\":\"R\",\"variant\":\"httr\"},{\"key\":\"r\",\"label\":\"R\",\"variant\":\"RCurl\"},{\"key\":\"ruby\",\"label\":\"Ruby\",\"variant\":\"Net::HTTP\"},{\"key\":\"shell\",\"label\":\"Shell\",\"variant\":\"Httpie\"},{\"key\":\"shell\",\"label\":\"Shell\",\"variant\":\"wget\"},{\"key\":\"swift\",\"label\":\"Swift\",\"variant\":\"URLSession\"}]","languageSettings":[{"key":"csharp","label":"C#","variant":"HttpClient"},{"key":"csharp","label":"C#","variant":"RestSharp"},{"key":"curl","label":"cURL","variant":"cURL"},{"key":"dart","label":"Dart","variant":"http"},{"key":"go","label":"Go","variant":"Native"},{"key":"http","label":"HTTP","variant":"HTTP"},{"key":"java","label":"Java","variant":"OkHttp"},{"key":"java","label":"Java","variant":"Unirest"},{"key":"javascript","label":"JavaScript","variant":"Fetch"},{"key":"javascript","label":"JavaScript","variant":"jQuery"},{"key":"javascript","label":"JavaScript","variant":"XHR"},{"key":"c","label":"C","variant":"libcurl"},{"key":"nodejs","label":"NodeJs","variant":"Axios"},{"key":"nodejs","label":"NodeJs","variant":"Native"},{"key":"nodejs","label":"NodeJs","variant":"Request"},{"key":"nodejs","label":"NodeJs","variant":"Unirest"},{"key":"objective-c","label":"Objective-C","variant":"NSURLSession"},{"key":"ocaml","label":"OCaml","variant":"Cohttp"},{"key":"php","label":"PHP","variant":"cURL"},{"key":"php","label":"PHP","variant":"Guzzle"},{"key":"php","label":"PHP","variant":"HTTP_Request2"},{"key":"php","label":"PHP","variant":"pecl_http"},{"key":"powershell","label":"PowerShell","variant":"RestMethod"},{"key":"python","label":"Python","variant":"http.client"},{"key":"python","label":"Python","variant":"Requests"},{"key":"r","label":"R","variant":"httr"},{"key":"r","label":"R","variant":"RCurl"},{"key":"ruby","label":"Ruby","variant":"Net::HTTP"},{"key":"shell","label":"Shell","variant":"Httpie"},{"key":"shell","label":"Shell","variant":"wget"},{"key":"swift","label":"Swift","variant":"URLSession"}],"languageOptions":[{"label":"C#
