How does the web work

Data Format

HTML

Addressing

URL

How does the Web work?

(currently)

Transport

HTTP

3 simple protocols:

Data FormatsHTML (HyperText Markup Language) provides the data format for native documents

AddressingURLs (Uniform Resource Locator) provides an addressing mechanism for web resources

TransportHTTP (HyperText Transfer Protocol) defines transfer of resources between client and server

How does the Web work?

The Netsofthome page

1 User clicks on link to the address (URL)http://www.netsoft.com/hello.html

2 Browser converts link to HTTP command (METHOD):

Connect to computer at www.netsoft.com

GET /hello.html

3 Remote computer sends file

Welcome to

Netsoft

<HTML>

<TITLE>Welcome</TITLE>..

<P>Welcome to <B>Netsoft</B>

Web server

Web Browser

4 Local computer displays HTML file

Linking what s required
Linking – what’s required?

  • User - ‘easy’

  • Library - accurate

  • Publishers - secure

  • Intermediary - standard

Linking mechanisms
Linking Mechanisms

URL-based include:

  • explicit filename

    http://www.ariadne.ac.uk/issue24/intro.html

  • derived filename, e.g. ISSN, SICI

    http://www.jstor.ac.uk/journals/10624783.html

  • script, e.g.

    http://www.esajournals.org/esaonline/?request=get-abstract&issn=00129658&volume=077&issue=08&page=2302

Linking mechanisms1
Linking Mechanisms

  • The Digital Object Identifier (DOI):

  • A unique identifier assigned to a digital object.

  • A way of accessing an object (e.g. a full text article) without having to know its URL - the DOI identifies the object itself, not the place where it is stored.

  • Persistent - as long as the object exists, so does the DOI.

Getting Technical - Linking

UKSG SRM


DOI: Dumb Old Identifier

“Dumb” number - doesn’t relate to the object, couldn’t be guessed - like a phone number.

10.1000/123456789

Prefix - given to the rights owner e.g. the publisher

Suffix - any unique alphanumeric string

e.g. 10.1074/jbc.M004545200

Pat Harris, Executive Director of NISO:

"One message we hear is that the new business model will be enabled by information technology with standards at the core. This is where NISO fits in. …over five hundred years ago Guttenberg fundamentally changed communication and learning.

Today NISO's challenge is to create those standards that will enable the modern day Gothenburg Moment. Could it be the OpenURL?"

Openurl format base url query
OpenURL format ::=Base URL?Query

Base-URL = web address of the link resolver i.e. the address to which the OpenURL is being sent

http://LinkFinderPlus.library.edu?genre=article&issn=1234-5678&volume=12&issue=3&spage=1&epage=8

&date=1998&aulast=Smith&aufirst=Paul

Query = the metadata that the link resolver uses to identify and link to appropriate targets

Use of openurl technology in ac uk
Use of OpenURL Technology(in ‘ac.uk’)

  • Maximise use of (appropriate) e-resources

    • to increase use of (their) e-journals

    • provide links from bibliographic resources

  • Help with e-journal management – please!

  • All sources possible, targets limited to major ‘bundled’ deals – ‘slowly & accurately’

  • Launch ‘quickly but quietly’

    See ‘Talking Shop’ reports at http://www.mimas.ac.uk/metadata/ITAM/sfx.html

    Also, comparison of SFX, SIRSI, LinkFinder+ and 1Cate in:

    “Context-sensitive Linking: It’s a Small World After All”, Collins & Ferguson, Serials

    Review, Volume 28, Issue 4, Winter 2002, Pages 267-282.

The open archives initiative
The Open Archives Initiative

  • 1999 Universal Preprint Service (UPS)

    • Multi-disciplinary collection of technical reports, conference papers, articles, e-print servers, etc.

    • Services provided on “harvested metadata”

  • Data Providers / Service Providers

  • Sharing versus searching

  • OAI is only about metadata – not full text

  • OAI is neutral about nature of metadata and the resources described

UKSG SRM


Oai metadata harvesting framework
OAI Metadata Harvesting Framework

  • Simple mechanism for sharing metadata records

  • Records shared over the web (ie HTTP as XML)

  • ‘Client’ can ask metadata server for

    • all records

    • all records modified in last ‘n’ days

    • info about sets, formats, etc.

  • Specific application: self-archiving via e-print servers in/for all institutions

UKSG SRM


  • Consistent, Credible & Compatible Usage Statistics

  • Code of Practice for:

    • Data elements to be measured

    • Definitions of these data elements

    • Output report formats/delivery/frequency/granularity

    • Methods for measurement and use

  • AAP, ALPSP, ARL, ASA, EDItEUR, JISC, NCLIS, NISO, PA, STM, UKSG
