DSpace and Persistent IDs

DSpace and Persistent IDs

• Researchers require a stable point of reference
  for their works
• DSpace uses the CNRI Handle System for creating
  identifiers
• DSpace uses Handles primarily as a means of
  assigning globally unique identifiers to objects.
  
• Each site running DSpace needs to obtain a unique
  Handle 'prefix' from CNRI
• Handles are assigned to communities, collections,
  and items

DSpace and Persistent IDs

• The Handle system features a global resolution
  infrastructure
• One can enter a Handle into any service (e.g. Web
  page) that can resolve Handles, and be directed
  to the object (in the case of DSpace a
  community, collection or item
• The DSpace site runs a 'Handle server' that can
  accept and resolve incoming resolution requests.
• DSpace uses the CNRI Handle infrastructure only
  at the 'site' level
• It is the responsibility of the DSpace site to
  maintain the association between a full Handle
  and the community, collection or item in question

DSpace and Persistent IDs

• Bitstreams in DSpace also have a persistent
  identifier
• Each bitstream has a sequence ID, unique within
  an item
• This sequence ID is used to create a persistent
  ID
