October 2001

1. Unique Names

Keyword: Hooker’s Street Rods

• Names as unique identifiers: includes numbers and codes• Printable names (the business card problem)• Direct navigation as important application

Keywords (Keywords ( 삼성삼성 ))Internationalized Domain NamesInternationalized Domain Names

(www.(www. 삼성삼성 .co.kr).co.kr) Domain Name SystemDomain Name System(www.samsung.co.kr)(www.samsung.co.kr)

IP Addressing SystemIP Addressing System (231.133.53.23) (231.133.53.23)

2. Above DNS

• New names require a new naming layer (layered approach)• A Keyword hides a URI (resource physical address)

3. In all languages

6. With multiple interoperable namespaces

• Differentiated• context (language, country, service type…)• syntax (e.g. numbers, idn.idn, codes, prefixes…)

• Interoperable• One standard resolution protocol (CNRP++)• One standard registration protocol (PROVREG)

• Ubiquitous• Cross-platform client libraries implementing the protocols

7. Layered resolution (bridging the past & the future syntaxes)

• ALL syntaxes means that this is the last resolution layer• Express & Recognize a namespace specific syntax (past: DNS, IDN, present: Keyword, enum, IDN.IDN, future: Natural language interface (voice), programmable Web (operator + resource identifier = human command)• Resolution patterns requirements (determination, delegation, cascade, aggregation)

• We need to understand the difference between Names & Modifiers: page pepe le pue, Hilton in Palo Alto
