What Do Publishers Need to

Do?1.Sign up at http://www.crossref.org/06members/citedby_linking_signup.html

2.Deposit reference lists for each document at CrossRef

3.Query CrossRef (using the document DOI) for a list of all DOIs citing a document.

Depositing References

•No special permission is required to make deposits

•Two methods:

a)XML

b)Simple Text Query (STQ)

a) XML Reference Deposit

Deposit as many citations as the article has,

but the list replaces whateverwas deposited before

Can include just a DOI

Not yet supported, but send it if it’s all

you have

Used to line-up a return match with a specific

query item

a) XML – Reference Deposit<?xml version="1.0" encoding="UTF-8" ?> <doi_citations_batch version="1.0.1" xmlns="http://www.crossref.org/doi_citations_schema/3.0.3" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.crossref.org/doi_resources_schema/3.0.3 http://www.crossref.org/schema/deposit/crossref3.0.3.xsd"> <head> <doi_batch_id>123456</doi_batch_id> <depositor> … </depositor> </head> <body> <doi_citations> <doi>10.5555/small_md_0001</doi> <citation_list> <citation key="ref1"> <journal_title>Current Opinion in Oncology</journal_title> <author>Chauncey</author> <volume>13</volume> <first_page>21</first_page> <cYear>2001</cYear> </citation> <citation key="ref2"> <doi>10.5555/small_md_0001</doi> </citation> <citation key="ref3"> … </citation> </citation_list>

The DOI of the ‘citing’ article

A ‘cited’ tagged reference

The DOI of a ‘cited’ reference

a) XML – Reference Deposit Results<?xml version="1.0" encoding="UTF-8"?><doi_batch_diagnostic status="completed" sp="CR4"> <submission_id>334701547</submission_id> <batch_id>04260730</batch_id> <record_diagnostic status="Success"> <doi>10.5555/small_md_0001</doi> <msg>Successfully updated</msg> <citations_diagnostic> <citation key="ref1" status="resolved_reference"> 10.1016/0197-4580(90)90059-9 </citation> <citation key="ref2" status="resolved_reference">10.5555/small_md_0001</citation> <citation key="ref3" status="stored_query"></citation> </citations_diagnostic> </record_diagnostic> <batch_data> <record_count>1</record_count> <success_count>1</success_count> <warning_count>0</warning_count> <failure_count>0</failure_count> </batch_data></doi_batch_diagnostic>

The DOI of the ‘citing’ article

b) Simple Text Query (STQ)

http://www.crossref.org/SimpleTextQuery/

b) STQ Reference Deposit

b) STQ Reference Deposits

• The STQ form submits reference

deposits to the CR system

• You receive an e-mail with

deposit results

b) STQ Reference Deposits

• The deposit will contain all the references

STQ can extract

• Parsed references that do not find a DOI

submitted as a stored metadata query

• References that do find a DOI submitted

as a DOI

b) STQ Reference Deposits

• Each deposit will overwrite previous

deposits

• Make each request a complete list of all

references

• Delete a reference by re-submitting

deposit without the reference

The DOI of the article containing this reference

b) STQ Reference Deposit

Paste in references

Get DOIs

Submit “Forward Link”

2. Querying for Cited-by Links

•A CrossRef user account must have permission to submit Cited-by Linking queries

•The CrossRef user can only retrieve Cited-by links to articles “owned” by that user’s prefix

<?xml version = "1.0" encoding="UTF-8"?><query_batch version="2.0" xmlns = "http://www.crossref.org/qschema/2.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.crossref.org/qschema/2.0 http://www.crossref.org/qschema/crossref_query_input2.0.xsd"> <head> <email_address>ckoscher@crossref.org</email_address> <doi_batch_id>fl_001</doi_batch_id> </head> <body> <fl_query alert="false"> <doi>10.1103/PhysRev.100.935</doi> </fl_query> </body></query_batch>

set alert="true" if we want to receive future emails when someone else cites this article

This is the DOI of the article that is 'cited’; We must be the owner to retrieve

any cited-by links

XML – Cited-by Query

XML --Cited-by Query

Results

• The article being cited

• # of times the citing item is itself cited
