An important assumption underlying the Web and many other hypermedia |
10 |
|
systems is that an identifier, if it is to be resolvable, must |
11 |
|
include information about where to find the resource it identifies. |
12 |
|
Berners-Lee [ref NameMyth] argues that identifying documents |
13 |
|
by unique, completely random identifiers may be desirable, |
14 |
|
as unlike for a URL, there is little reason for a random identifier |
15 |
|
ever to be changed, but that it is not possible to resolve such names |
16 |
|
on a global scale. However, recent development in peer-to-peer systems |
17 |
|
has made scalable indexing systems possible, rendering this assumption |
18 |
|
obsolete. This, we believe, is the most important result of |
19 |
|
peer-to-peer research with regard to hypermedia. |

Binding documents to servers has been necessary to make the Web scalable, |

as no central index of documents was needed. |

Berners-Lee [ref NameMyth] argues that identifying documents |

|
by unique, completely random identifiers may be desirable because |
83 |

there is never a need to change such an identifier because e.g. a server |

moves to a different organization, but that it is not possible to |
