Presentation Overview

• OpenURL Linking Architecture

• Metadata

• Identifiers

• Limitations of DOIs in OpenURL

• Appropriate Copy

OpenURL

• National Information Standards Organization

(NISO)

• Standardizes:

– Data used to identify or describe an object – Syntax used to package the data

Origin  Resolver  Targets

OpenURL from ORIGIN to RESOLVER

• http://cat.cisti.nrc.ca:4550/resserv?issn=

0302-9743&volume=2301

RESOLVER generates links to TARGETS

• FULL TEXT:

http://springerlink.metapress.com/openurl.asp? genre=issue&issn=0302-9743&volume=2301

• SEARCH:

Metadata

• Metadata

– Many bits of data needed to identify an object

– Information about information – Descriptive

Identifiers

• Identifiers

– Code uniquely identifying an object – Ex.: Digital Object Identifier (DOI):

11

RP Article via DOI Handle System

Limitations of DOIs in OpenURL

• Origin sends identifier only (no metadata)

• Few targets recognize DOI

• Not enough information for providing

appropriate copy

13

Appropriate Copy

• Offer a relevant resource to the user

– Who is requesting?

– What are we licensed to offer to that user?

• Example: Article Request

– NRC: Full Text of Licensed Article

Origin: WebOPAC

Origin: WebOPAC

17

Solution

• Use identifier resolution system

– CrossRef reference database

DOI  CrossRef  Metadata

– With metadata, resolver can check against local holdings and offer appropriate copy

Linking Architecture

License & holdings information

User authentication & recognition
