      A process where a researcher or organization plans and then executes a series of steps
       intended to increase the field of healthcare-related knowledge.  This includes studies
       of safety, efficacy, comparative effectiveness and other information about medications,
       devices, therapies and other interventional and investigative techniques.  A ResearchStudy
       involves the gathering of information about human or animal subjects.
      
      
      
      
      
        
        
        
        
        
        
      
      
        
        
        
        
        
        
      
      
        
        
        If a resource is contained in another resource, it SHALL NOT have a meta.versionId or
         a meta.lastUpdated

      The logical id of the resource, as used in the URL for the resource. Once assigned, this
       value never changes.
      The only time that a resource does not have an id is when it is being submitted to the
       server using a create operation.
      
      
      
        
        
        
      
      
        
      
      
    
    
      
      

             of the resource and that modifies the understanding of the element that contains
             it and/or the understanding of the containing element's descendants. Usually modifier
             elements provide negation or qualification. To make the use of extensions safe
             and managable, there is a strict set of governance applied to the definition and
             use of extensions. Though any implementer is allowed to define an extension, there
             is a set of requirements that SHALL be met as part of the definition of the extension.
             Applications processing a resource are required to check for modifier extensions.
Modifier extensions SHALL NOT change the meaning of any elements on Resource or
             DomainResource (including cannot change the meaning of modifierExtension itself).">modifierExtension</a>

      Language is provided to support indexing and accessibility (typically, services such as
       text to speech use the language tag). The html language tag in the narrative applies 
       to the narrative. The language tag on the resource may be used to specify the language
       of other presentations generated from the data in the resource  Not all the content has
       to be in the base language. The Resource.language should not be assumed to apply to the
       narrative automatically. If a language is specified, it should it also be specified on
       the div element in the html (see rules in HTML5 for information about the relationship
       between xml:lang and the html lang attribute).
      
      
      
        
        
        
      
      
        
      
      
        
          
            
          
        
        
          
        
        
          
        
        
        
        
          
        
      
    
    
      
      
      A human-readable narrative that contains a summary of the resource, and may be used to
       represent the content of the resource to a human. The narrative need not encode all the
       structured data, but is required to contain sufficient detail to make it &quot;clinically
       safe&quot; for a human to just read the narrative. Resource definitions may define what
       content should be represented in the narrative to ensure clinical safety.
      Contained resources do not have narrative. Resources that are not contained SHOULD have
       a narrative. In some cases, a resource may only have text with little or no additional
       discrete data (as long as all minOccurs=1 elements are satisfied).  This may be necessary
       for data from legacy systems where information is captured as a &quot;text blob&quot;
       or where text is additionally entered raw or narrated and encoded in formation is added
       later.
      
      
      
      
      
      
      
        
        
        
      
      
        
      
      
      
        
        
      
    
    
      
      
      These resources do not have an independent existence apart from the resource that contains
       them - they cannot be identified independently, and nor can they have their own independent
       transaction scope.
      This should never be done when the content can be identified properly, as once identification
       is lost, it is extremely difficult (and context dependent) to restore it again.
