aDORe repository
aDORe: a modular, standards-based Digital Object Repository
- http://african.lanl.gov/aDORe/projects/adoreArchive/index.html - project web site, including software download
- http://arxiv.org/abs/cs.DL/0502028 - (an early Google hit for aDORe) - a detailed document about aDORe architecture, but rather heavy going. This seems to be a bit disconnected from other information on the web site.
- http://comjnl.oxfordjournals.org/cgi/rapidpdf/bxh114v1.pdf - - aDORe: A Modular, Standards-Based Digital Object Repository - link needs Computer Journal subscription.
The paper cited above describes aDORe as a digital repository system that supports complex metadata (MPEG-21 framework) and multiple datastreams for a digital object. Digital objects are represented by MPEG-21 Digital Item Declaration (DID) XML wrappers, via which metadata and constituent datastreams can be accessed. This seems to relate very closely to the Pathways project model (which is not surprising, considering the people and institutions involved).
The web site itself gives less obvious import to MPEG-21 specifically, but describes a more generic architecture based on XMLTape wrappers and ARCfile constituent streams. A key idea seems to be that XMLtapes are used to represent (or wrap) digital object, but are also exposed as autonomous OAI-PMH repositories. From our point of view, for accessing images within articles, this is a powerful idea.
The other key technology seems to be the use of an OpenURL resolver to access constituent data streams (this theme also re-appears in the Pathway and ORE projects).
Related papers (there seem to be a vast array of overlapping papers about this work, so it's difficult to select a reasonably representative distillation:
- http://african.lanl.gov/aDORe/projects/adoreArchive/docs/20060216_adore.ppt, aDORe Archive: File-based storage of Digital Objects and constituent datastreams - this powerpoint presentation gives a useful high-level overview of concepts.
- http://public.lanl.gov/herbertv/presentations/ECDL2005/aDORe_XMLtape-ARCfile.ppt, File-based storage of Digital Objects and constituent datastreams: XMLTapes and Internet Archive ARC files (Presentation) - this powerpoint presentation usefully links the XMLtapoe concept with the use of MPEG-21 DIDL (essentially, the XMLtape wraps the DIDL). It also clarifies that aDORe is file-based, rather than built using a database.
- http://library.lanl.gov/cgi-bin/getfile?LA-UR-05-6633.pdf, Representing Digital Assets Using MPEG-21 Digital Item Declaration - seems to be a relatively recent paper fromn LANL about using MPEG-21 DID to represent digital assets, with some history of related MPEG standards.
