1 STM Innovations Meeting December 7 th, 2001

2 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 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 n=1&_method=citationSearch&_origin=OJPS&_volkey= % 23214%237&returnURL=http://link.aip.org/link/%3fAPL/79/2946/1& _version=1&md5=bd1d96ce200e af1b33e0248da

4 4 Web Browser DOI Directory Basic DOI Resolution

5 5 Web Browser DOI Directory Parameter Pass Through

6 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 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 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 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 3 rd parties in supply chain

10 10 Multiple Resolution for Journals

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

15 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 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
