How does the Web (currently) work? 3 simple protocols: Data Format HTML Addressing URL Transport HTTP Data Formats HTML (Hyper. Text Markup Language) provides the data format for native documents Addressing URLs (Uniform Resource Locator) provides an addressing mechanism for web resources Transport HTTP (Hyper. Text Transfer Protocol) defines transfer of resources between client and server Getting Technical - Linking UKSG SRM 3

How does the Web work? The Netsoft home 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 Welcome to Netsoft Web Browser 3 Remote computer sends file <HTML> <TITLE>Welcome</TITLE>. . <P>Welcome to <B>Netsoft </B> Web server 4 Local computer displays HTML file Getting Technical - Linking UKSG SRM 4

Linking Mechanisms The Digital Object Identifier (DOI): • is a unique “dumb number” assigned to an entity • remains persistent for the life of the digital object • is comprised of a prefix and a suffix separated by a forward slash One or more prefix per content producer The suffix can be any type of identifier The suffix can be assigned to entities of any size or granularity or any file type Getting Technical - Linking UKSG SRM 9

Linking Mechanisms The DOI is analogous to the Universal Product Code (UPC) bar code But… the DOI is not equivalent to a Universal Resource Locator (URL) A URL points to the location (to an instance) of content. Whereas a DOI permanently names that CONTENT and facilitates retrieving multiple instances of it, or of other associated information Getting Technical - Linking 10 UKSG SRM

Open. URL 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 Open. URL? " Getting Technical - Linking 12 UKSG SRM

Use of SFX in ‘ac. uk’ • Maximise use of (appropriate) e-resources 1. to increase use of (their) e-journals 2. 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’ Getting Technical - Linking 17 UKSG SRM

The Open Archives Initiative • 1999 Universal Preprint Service (UPS) • Multi-disciplinary DL of technical reports, 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 Getting Technical - Linking 18 UKSG SRM

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 modified in last ‘n’ days – info about sets, formats, etc. • Specific application: self-archiving via e-print servers in/for all institutions Getting Technical - Linking 19 UKSG SRM
