General

• XML to describe components of a digital object
• Administrative and technical metadata most
  extensively defined parts
• Descriptive metadata often handled by pointing to
  external schemas (MODS, EAD, MARC, MOAII)
• Structural map most important part of METS
  document defines structure of digital objects
  and their internal relationships

Technologies used to store/retrieve METS documents

• Relational databases used
• XSLT for display
• Open source technologies

METS in DSpace

• Admin and technical metadata in DSpace conforms
  to METS
• Descriptive metadata in Dublin Core
• Can add METS documents as attachments to a
  DSpace submission

9
METS in Fedora

• Fedora intended to be a repository, not a digital
  library
• File pointers, managed content, and internal
  metadata data streams incoporated by Fedora
  architecture
• METS used as SIP and DIP

Summary of Technologies Used for METS Storage and
Display

• Relational databases
• Most developers are using databases willing to
  share database structures
• Requires extensive understanding of database
  structures
• XSLT for display (several exist for sharing)
• Requires server-based transformation
• XML files used for transmission
