Registration agencies: DOI deployment doi> doi> NUMBERING Any form of identifier DESCRIPTION <indecs> framework: DOI can describe any form of intellectual property, at any level of granularity ACTION Handle resolution allows a DOI to link to any and multiple pieces of current data POLICIES DOI adds value To do this incurs costs: • Number registration – validation, maintenance, metadata, guidance • Infrastructure – resolution service, scaling, development • Governance – rules, further development DOI deployment; principles • DOI free at point of use • Costs of assignment paid by assigner • Allow different business models – allow anyone to do what they want • Distributed system – agencies DOI deployment; principles • IDF to provide governance layer only – using a federation of registration agencies • IDF sets out minimum criteria for registration agencies: – rules of the road: not journey maps – technical; information management; $ • Does not prescribe details of individual businesses • Comparable models work well: – EAN/UPC; Visa; ISBN etc. DOI deployment: advantages • Variety of potential business models – currently $1000 per prefix one off – one size does not fit all; need more flexibility • Variety of naming authority models – currently one per registrant – move to appropriate level; e.g. journals – allow subdivision (10.1000.2/123) • RA’s will probably offer applications – number registration alone not a “business”?

Questions as to acceptability • Separate database – easy but raises issues of access • Pointer entry (data type) in DOI record – best guarantee of commonality; likely to be introduced Issues (4): Which metadata? (semantics) • DOI approach based on <indecs> work – practical implementation ONIX etc • “DOI Genre” for each i.p. type – functionally (arbitrarily) defined • Incorporates a common DOI kernel: – – – – DOI; DOI genre; Identifier (legacy); Title Type (work, manifestation, etc) Origination (original, derivative, replica, etc) Primary agent and agent role • Further articulation and guidelines DOI Genre 1 Compulsory kernel metadata for any DOI Compulsory metadata for this Genre All metadata in well-formed structure Issues (5): Mis-use • Seen already: – duplication of prefix; DOIs not entered into directory; citing of early DOIs • Who will determine rules? – May be different guidelines for different areas • and who will police them? • Some checks can be built into system – e.g. attempted duplication Issues (6): Explaining • “missionary work” – identifiers: precision about what is identified (ISO TC46?) – functional granularity; well-formed metadata, etc. • who will pay for this? • what can we learn from other efforts? – e.g. ISBN • Best explained by examples: applications • Encouraging signs of take off – e.g. E Books Issues (7): Building on incomplete foundations • DOI only now going from “zero genre” to compulsory Genre metadata – pioneering difficulties • Resolution technology not ubiquitous – plug-ins and proxies are work arounds • Who “owns” <indecs> compliance? • Guidelines are incomplete/evolving Issues (8): quality control • Who defines Genres and mappings, ensures conformance? – e.g. DOI-X, Crossref (journal articles) – IDF “testing service” at cost? • Who ensures quality control of content? • Who is the authority for each element? • What are the business model implications? Issues (9): Business models • DOI Registration Agencies – based on similar models – e.g. UPC/EAN bar codes, ISBN • Relationships between: – agencies and IDF – agencies and customers – agencies and agencies IDF / Operating Federation RA RA C C RA C Issues (10): relation to existing schemes? • Many ISO entities have metadata records – ISBN, ISSN, etc - widely used • May not be consistent with each other • May not be consistent with indecs mapping • May not be available for DOI registration on ideal “do it once” basis – commercial considerations of those agencies • Can metadata be shared? Issues (11): management of standards • DOI and indecs based on open standards • Who directs evolution? – governance structure, maintenance agency (NISO standard) – likely not to be of commercial value alone • Who will invest the resources necessary to make improvements and prevent stagnation? – IDF set up as collaborative forum – Long term funding and sustainability? – Funding through use (like bar codes) Registration Agencies • Basis for Deployment outlined (end of 1999) – cost recovery • RA Working Group: initially 3 members/RAs Terms document - now available Letter of Intent - now available • CrossRef first RA to sign up • 10-15 other RA candidates discussing with IDF • RAs will be part of the Foundation – governance and close collaboration IDF in relation to Registration Agencies • does not own or direct – RAs are independent businesses, members of the Foundation, part of agreed operating federation • does not compete with existing agencies – (e.g. ISBN): we mandate declaration of ISBN etc. • does not determine business models – needs to be done by the sector • does not enforce one single metadata standard – just principles • neither “privatises” nor “liberates” data – only a minimal kernel (like book title) • provides community focus and consensus
