1. 1 IDF Annual Members Meeting June 23, 2004 IDF – Annual Members Meeting Implementation Update

2. 2 IDF Annual Members Meeting June 23, 2004 Key benefits of the CrossRef system As a business infrastructure for linking No bilateral linking agreements needed – an agreement with CrossRef is a linking agreement with all CrossRef publishers Publishers maintain their own business models while enhancing value and functionality of their content Collaborative foundation for developments in information access As a technology service A search engine to find DOIs based on an articles metadata (title / author / volume / issue / page / year) Operates an OpenURL 1.0 resolver As a technology provider Standards and industry coordination Linking expertise

3. 3 IDF Annual Members Meeting June 23, 2004 CrossRef Indicators 307 participating publishers 290 libraries and consortia 33 agents and affiliates 11.2 million items, 9,500 journals 6 million DOI resolutions/month >2.5 million DOIs retrieved per month ~300,000 records updated per month 650,000 book and proceedings DOIs

4. 4 IDF Annual Members Meeting June 23, 2004 CrossRef DOIs being clicked

5. 5 IDF Annual Members Meeting June 23, 2004 What's New at CrossRef Forward linking is now operational Provides cited-by links CrossRef search pilot with Google is ongoing Expanded content Gray literature: working papers, dissertations, reports, patents More granular: images, tables, figures, datasets Increased usage reports DOI clicks by prefix, title and article Improved infrastructure : local secondary handle

6. 6 IDF Annual Members Meeting June 23, 2004 Multiple Resolution Built on commonly available technology Server side includes (servlets that build HTML on the fly) Dynamic HTML (menu operation) DOI API (application profiles and services) Targeted at helping solve the appropriate copy problem A publisher hosts their journal in two locations Technology is the easy part, governance is harder Control over the menu structure and content Access to the DOI (who gets to add what?) Management of the many targets

7. 7 IDF Annual Members Meeting June 23, 2004 Architecture – Two approaches Metadata storage DOI CrossRef On the fly Batch pre-display DOI Registration Page loaded in a browser 1 Server side include called to populate MR info 2 Servlet gets DOI AP context info 3 Menu rendered on page 4 CrossRef alerts host of of new MR data for a DOI 1 Host retrieves MR info 2 Page rendered with menu info built in 3

8. 8 IDF Annual Members Meeting June 23, 2004 Use of the DOI API One application profile, with several services 10.ap/profile_cr_mr_menu 10.service/cr_mr_svc_default-form-primary 10.service/cr_mr_svc_alt-form-primary 10.service/cr_mr_svc_related-links-primary 10.service/cr_mr_svc_related-works-primary … A working On the fly prototype is ready Uses API version 2.1 Feedback given to CNRI on two items Use to demo/pilot appropriate copy solution with real publisher data

9. 9 IDF Annual Members Meeting June 23, 2004 Use of DOI Services Service contexts hold segments of menu data Menu organization is controlled by policy
