Mapping code system OIDs to URIs

codesystem-map.js

/**
 * The mapping of code system codes in OID form (numbers) to URLs. FHIR wants all
 * code systems to be given as a URL (or at least a URI/URN). This is the algorithm
 * for determining it (https://www.hl7.org/fhir/terminologies.html#system):
 * 1) If the code system is found in https://www.hl7.org/fhir/terminologies-systems.html use
 *    the URL provided there.
 * 2) If the publisher of the code system has defined a specific URL to use with FHIR, use that.
 * 3) If the code system can be found in http://registry.fhir.org/NamingSystem and its status is
 *    active, use that.
 * 4) If an OID is registered at http://hl7.org/oid use the form 'urn:oid:[oid]' where [oid] is
 *    the original OID.
 * 5) If all else fails, come up with your own unique URL
 *
 * NOTE: the URLs do not need to be working web links, i.e. putting the link in your browser does not need to take you to a working homepage. But it can.
