Architecture highlights: · Every DOI (application and administrative) has one or more associated application profiles. · All DOI handles are interlinked within the DOI handle application. · The DOI handle application is a self-contained implementation within the Handle system and is independent of other handle applications and intentions (eg handle type semantics). · XAD - An eXtensible API for DOI is required. A preliminary is given. Hope this might be of some interest and not too abstruse. There's a picture inside and lots of "actionable" (virtual) DOIs. What more can I say? RDF-compliant, even :-) Disclaimers: This is still an early draft and some of the language may be a little uneven regarding DOI vs Digital Object, and Application vs Application Profile. Also I've used a DOI genre now as shorthand for a DOI content type (Journal Article, say) - this may still be misleading although seems (to me) to be useful as the new concept of Application Profile has a better tie-in with application-specific metadata. I've not distinguished too well the difference between services for acquiring kernel and application metadata in the CrossRef application - we're still working on that. I've tried also to stike some kind of balance between specificity and genericity in the DOI handle types although there's lots of scope for improvement. Be glad to get any feedback.
