  1. STM Innovations Meeting December 7th, 2001

  2. Parameter Passing • Target to implement by April 2002 • Parameter sub-group of TWG • More difficult than originally thought – tied in with other IDF developments • Parameter white paper out for review – will be distributed to members in January 2002 • A parameter is when extra information is sent along with the DOI

  3. Current Parameter Use • URLs can have parameters attached • Some CrossRef publishers use parameters with bilateral linking arrangements • Example of link into ScienceDirect from OJPS • http://www.sciencedirect.com/science?_ob=GatewayURL&_urlVersion=1&_method=citationSearch&_origin=OJPS&_volkey=03048853%23214%237&returnURL=http://link.aip.org/link/%3fAPL/79/2946/1&_version=1&md5=bd1d96ce200e1768571af1b33e0248da

  4. Basic DOI Resolution http://dx.doi.org/10.1006/jmbi.1997.1400 Web Browser http://www.idealibrary.com/links/doi/10.1006/jmbi.1997.1400 DOI Directory

  5. Parameter Pass Through http://dx.doi.org/10.1006/jmbi.1997.1400?“parameter” Web Browser http://www.idealibrary.com/links/doi/10.1006/jmbi.1997.1400?“parameter” DOI Directory

  6. Parameters • Common set of parameters (10 parameters) • Where the link is from, return URL, DOI of the originating article, encrypted key • Central DOI proxy (dx.doi.org) will only pass parameters to those publishers that are “parameter enabled” • Publisher can add parameters to all their DOIs (don’t need to know the publisher) • “Parameter enabled” publishers will need to recognize the common set of parameters

  7. Benefits of Parameters • Identify originating publisher/system • Identify originating article DOI • Identify title of originating journal (or book) • Customize response pages w/return link to originating article • Special trading rules

  8. Multiple resolution • Currently One DOI = One URL • Multiple Resolution is a single DOI associated with many possible actions • multiple URLs for dispersed mirror sites • pointer to a metadata record • different versions (“get html” or “get pdf”) • author bio • rights information….and more

  9. Multiple Resolution • DOI Services - complex • Common infrastructure for all RAs • DOIs registered by different RAs should act the same • How to figure out what options are available for a DOI? • Multiple resolution information must be expressed in standard XML format • Publisher registering DOI will deposit multiple resolution data – what about 3rd parties in supply chain

  10. Multiple Resolution for Journals

  11. CrossSearch • What: Cross-publisher, full-text search (search results link to publishers using DOIs) • Why? CrossRef was set up for reference linking • CrossRef is collaboration that creates infrastructure enabling members to add value to their services and to improve access to full text content for scholars • CrossSearch will allow members to add value to their services and will provide scholars a broad, cross-disciplinary search with quick access to full text

  12. CrossSearch • Scholars are already using Google and other services to search • Government initiatives: PubMed Central and PubScience • OAi (Open Archives) – distributed searching of e-print archives is already underway

  13. Technical Architecture • Distributed search (sending out queries and consolidating results) – won’t work • Crawling: content indexed by spider (cf Google) • Content Collection: full text content collected for indexing • Hybrid approach may be the best • Search would be offered on publisher site – query sent to central index – results returned (in XML) for presentation within publisher’s site

  14. XML Full Text XML Full Text XML Full Text Collection Service CrossSearch Index 1) Incoming Query 2) Search Results w/DOIs Publisher B Publisher A 3) User Clicks DOI CrossSearch

  15. CrossSearch Principles • Enabling infrastructure for members – focus would not be a destination site • Optional participation • Reciprocal terms – to use CrossSearch, member’s content must be indexed for others to search

  16. Business Model • Development and hosting to be outsourced • Free to end users? • Costs and fees: • Development costs • Number of items indexed • Conversion costs for content collection • Hardware costs • Royalty based on # of searches
