Historical Review

The current thinking about a next-generation architecture (what came to be known as DSpace+2.0) was articulated in Rob Tansley's presentation to the user group meeting in March 2004. In it he identified three 'areas for improvement', which were 'modularity', 'internationalization' and 'preservation'. Very roughly, each of these triggered a redesign proposal of the current architectural stack. From the 'top' of the stack:

...

• versioning support: See VersioningProposal – old discussion
• revisions in the identifier system – see e.g. this old persistent identifier discussion
• more flexible metadata options (often mentioned in connection with METS)
• support for relationships between bitstreams: see BitstreamRelationships
• more robust content format support
• alignment with the JSR170 data model
• revisiting how aggregation is modeled (currently done via Communities and Collections). May dovetail with JSR 170 approach
