Bug 3835: Design and implement OAI-PMH compliant harvest subsystem
Add support for request parameter "metadataPrefix=eml". This returns EML 2.1.0 records in an OAI-PMH format. EML 2.0.0 and 2.0.1 documents are first transformed to EML 2.1.0 using the eml201to210.xsl stylesheet that is packaged with the EML Utilities.

            Both 100 and 200 are referenced ids of pysical/distribtuion or software/implementation/distribution.


  		




  
  395
  
    
            Since we moved the access part to distribution element. If multiple access rules are present 


  		




  
  396
  
    
            which reference the same distribution node, they are combined in th order they appear in 


  		




  
  397
  
    
            additionalMetadata sections. A conflict can occur here if  "order" attributes dont match. Fail


  		




  
  398
  
    
            with an erroro message.


  		




  
  399
  
    
            


  		




  
  400
  
    
            Since both are referenced id (and no conflict), we don't need to keep the info. 


  		




  
  401
  
    
           So the output is blank - remvoing the additionalMetadata tree.

            300 is the referenced ids of pysical/distribtuion or software/implementation/distribution.

            But 400 is not. So output will be:
