1. Ray Denenberg Ralph LeVan Workshop 20 March 25, 2006; Washington Metasearch - the NISO Initiative

2. Metasearch

3. …. Also known as parallel search federated search broadcast search cross-database search

4. NISO: Definition, Problem, Challenge NISO Definition “search and retrieval spanning multiple databases, sources, platforms, protocols, and vendors at one time.” the Problem..... Current systems require users to know how to select, access and search specific databases. and the corresponding Challenge..... To create an environment that helps users find what they are seeking while minimizing what they need to know

5. NISO: “Why Bother?” Because most patrons do not care where information is or who packaged it. Because Google cannot do it all.

6. NISO Metasearch Initiative: Goals metasearch service providers offer more effective and responsive services content providers deliver enhanced content protect their intellectual property libraries deliver services that distinguish them from Google and other free web services.

7. Client Meta-searcher Database Metasearch Topological Entities

8. Client Meta-searcher Database Database Database Metasearch Topological Model

9. Recall Goals: metasearch service providers to offer more effective and responsive services content providers to deliver enhanced content and protect their intellectual property libraries to deliver services that distinguish them from Google and other free web services.

10. Entities Topological Client Metasearcher Database NISO Defined: Library Metasearch Provider Content Provider

11. Client Meta-searcher Database Service provider Content provider Library offer more effective and responsive services deliver enhanced content; protect intellectual property deliver “distinguished” services

12. Client Meta-searcher Database Database Database Protocol Protocol Protocol Model

15. NISO Metasearch Initiative

16. Metasearch Initiative Committee Charge identifying/developing standards/ best practices to improve interoperability between metasearch engines, and content providers identifying a simple search/retrieve protocol to help database providers more effectively interoperate with metasearching applications.

17. Metasearch Initiative Committee Charge - Boiling it Down interoperability between metasearch engines and content providers. protocol Identifying one - for interoperability between metasearch engines and content providers.

18. Task Groups TG 1: Access Management TG2: Collection Description TG 3: Search/Retrieve

20. Potential Authentication Technologies. Proprietary APIs NCIP. SIP2. LDAP Shibboleth Kerberos Athens (UK). PAPI Tequila Non-authenticated identification IP recognition Proxy Servers Referring URL Embedded data in URL Vendor provided Javascript Cookies Shouting

21. TG1 Recommendations Now IP authentication Username / Password Potential for the future Shibboleth

22. TG2: Collection Description Service Description: used by applications to determine how to access remote services. Collection Description: used by humans or applications to select collections from those made available by a metasearch service.
