Some times ago I’ve seen an interesting project, called Co-link…

This project is about the possibility to edit and insert a link where the user wants in the page that he is reading on the Web.

This technology was developed with the objective of letting any interactant create new associative links in a pre-existent text and/or add new destinations to a previous link.

The idea is nice: the user can insert in any esistent word in the text a link and also insert a new link in a pre-esistent link…

Another idea is this: multilink…

A multilink, or mlink, is a link that goes to one or more destinations.
A multilink is rendered as a popup menu that presents the targets as a list of menu items.
An item can be selected from the menu to follow the URL of the target, or a special item called “edit” can be selected to add, remove, or modify the targets of the multilink.
Targets are not embedded in the markup, but rather, stored in an external metafile linked to but exists independently from the page where the multilinks are defined.

Now the idea is not totally bad, but IMHO it’s dangerous…

There is an interesting discussion on Slashdot on it:

-> Multiple-Target Hyperlinks for the Masses

In fact when you find useful a tool like this, you have to understand that you include a semantic effort in the link concept…without using a standard way to make this semantic effort understandable by machines..

We can do it using RDF…

I’ve seen TiddlyWiki some months ago, and the idea and the non-linear written capacity has impressed me so much…

A TiddlyWiki is like a blog because it’s divided up into neat little chunks, but it encourages you to read it by hyperlinking rather than sequentially: if you like, a non-linear blog analogue that binds the individual microcontent items into a cohesive whole.

From Kemitix.net :

A self-contained HTML file that is a Wiki.
Editing the file locally it rewrites itself on disk as you save changes. There are a number of customisations that people have done to it, including one to use it hosted on a server.
I’ve been quite content with the basic Tiddler.
It is a wonderful demonstration of what you can do with javascript and a web browser, as if GMail and Google Maps weren’t good enough examples.

Or from another point of view, “The world as I see it“:

Ignore the silly name and focus in on the fact that this is a handy little wiki that can function like your own localized Wikipedia. And it’s totally portable, which means you can store it on a keydrive, email to yourself, whatever you want.
A very interesting tool, IMHO…

Another description from inolleb.com:

As it mentions, it is a single html file that contains everything you need. You then create tiddlers using WikiWords.
Tiddlers are blocks of information that link to other blocks of information and the links can continue infinately.
Ultimately it is extremely hard to describe. You will just have to check it out for yourself.
