What do we want?


OpenURL Framework

Problem:• How to provide context-sensitive links in a highly distributiveand heterogeneous information landscape

Solution:The OpenURL Framework:• Introduction of a new component - Institutional Linking Server (such as SFX)• OpenURL Specs – specs for interoperability between Info Resources and Linking Servers

Who is a Source ?

• Any information Resource: subscribed/non-subscribed; electronic journals; databases, catalogs, local repositories, portals

A&I

Library Portal

Course Management environment – eg Reading Lists:

The Right Thing


How do we make Sources OpenURL enabled?

• Typically, the application running the source does it

• What about “self-authored” web pages with citations (eg Reading lists)?

• Answer:

Either through added technology in the relevant application (eg Course Ware)

And/Or:

OpenURL Authoring Tools


Locating a Reference

• Through Discovery (Search) – Native Resources

• Through Discovery (Search) – Library Portal



• Known citation


The Role of the Link Server

• Provides the right links

• Tool to Save the citation and to construct the OpenURL (either directly or through a reference-management tool)

consistency across all resources!• Augmentation of missing information:

- the reference might not include an ISSN, yet the Target link (eg the Full-text repository) will most certainly require it.

- Abbreviated titles

Next Steps

• Personalization: different citation formats (MLA, APA, Chicago manual style,…)

• Push to courseware systems (API)


OpenURL

• Transportation of Metadata and Identifiers about the referent (the referenced work) and (some of) the context of the reference


OpenURL v0.1

• Transportation of Metadata and Identifiers about the referent (the referenced work) and (some of) the context of the reference

http://library.sfx.com/science?• id=doi:10.101/12345-abc &• genre=article &• aulast=Menakes & aufirst = Randy &

issn=12345678 & year = 2001 & volume = 2 & issue = 1 & spage=45 &

• pid = 76544 &• sid = OCLC:firstsearch

More stuff


OpenURL v0.1

• Focused primarily on bibliographic information (j-articles, books..)

• Fixed Metadata for by-value transportation Title=…&aulast=…&atitle=…&issn=…&year=…

&spage=…&…


OpenURL v0.1

• Limited in Scope (to Scholarly Information)• Limited in Schemes (descriptions an entity)• Limited in Context Entities ( only allowed for

Referrent; Referer; Resolver)• Limited in Encoding Options (only querystring)• Not extensible…

Van de Sompel, Herbert and Oren Beit-Arie. July/August 2001. “Generalizing the OpenURL framework beyond references to scholarly works: The Bison Futé model." D-Lib Magazine. 7(7).


Entities in OpenURL:• Referent (the referenced work)• Resolver (the OpenURL resolver/link server)• Referrer (the information source)• Requester (the user)• Referring Entity (eg citing Article)• ServiceType (what is requested)

OpenURL v1.0

Context Object

Descriptors:

• Identfiers

• By-Value Metadata

• By-Ref Metadata

• pid

Encoding:

• key/value (querystring)

• XML

• Others…

Transportation:

• HTTP GET/POST

• Others (SOAP; OAI-PMH…)

OpenURL v1.0OpenURL: A transportation mechanism of Context Objects

using HTTP GET/POST

Enables:• More information about the context more means to enable context sensitive and appropriate services

• Linking beyond the Scholarly Bibliographic Information domain:- Learning objects, Museum objects, Geo-spatial objects, video/audio,…
