DRS Audio Streaming Delivery Service Upgrade

OIS will upgrade the hardware for the DRS Streaming Delivery Service (SDS) during the last week of May (5/26-5/29). SDS will continue to function normally throughout the upgrade. No action is needed on the part of DRS depositors or SDS users.

As part of the upgrade, the format of the URLs referencing SDS will change.

• Currently
  
• http://dylan.harvard.edu:8080/sds/servlet/sds?id=393563  – old style
  will change to the URLs of a form
• After the upgrade
  
• http://sds.lib.harvard.edu/sds/audio/393563                       – new style
  

After the upgrade old style URLs will be automatically redirected to new style URLs:

• http://dylan.harvard.edu:8080/sds/servlet/sds?id=393563 ==> redirected to http://sds.lib.harvard.edu/sds/audio/393563
  

URNs (used in discovery systems such as HOLLIS, OASIS, etc.) will be automatically updated to reflect the change:

• Currently
  
• http://nrs.harvard.edu/urn-3:fhcl.loeb:sa2 resolves to http://dylan.harvard.edu:8080/sds/servlet/sds?id=393563
• After the upgrade
• http://nrs.harvard.edu/urn-3:fhcl.loeb:sa2 will resolve to http://sds.lib.harvard.edu/sds/audio/393563

DRS depositors: URNs created by the DRS Loader after the upgrade will automatically resolve to new URLs.

Thank you,
Vitaly
