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
2
Current Parameter Use
• URLs can have parameters attached
– Some CrossRef publishers use parameters with
bilateral linking arrangements
– Example of link into ScienceDirect from OJPS

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

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
7
Multiple resolution
• Currently One DOI = One URL
• Multiple Resolution is a single DOI
associated with many possible actions
–

–

–
8
multiple URLs for dispersed mirror sites
pointer to a metadata record
different versions (“get html” or “get pdf”)
author bio
rights information….and more
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

Multiple Resolution for Journals

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
11
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
12
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

3) User Clicks DOI
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
15
Business Model
• Development and hosting to be outsourced
• Free to end users?
• Costs and fees:
