Researchers in the fields of social science and medicine are debating how to fix an increasingly recognized problem: A lot of their findings are either outright wrong or can't be replicated. Satisfying as it would be to have a simple solution, to some extent they might just have to learn to live with uncertainty.

What They Don't Tell You

Hypertext Style: Cool URIs don't change. Cool URIs don't change What makes a cool URI? A cool URI is one which does not change. What sorts of URI change?

URIs don't change: people change them. There are no reasons at all in theory for people to change URIs (or stop maintaining documents), but millions of reasons in practice. In theory, the domain name space owner owns the domain name space and therefore all URIs in it. Except insolvency, nothing prevents the domain name owner from keeping the name. And in theory the URI space under your domain name is totally under your control, so you can make it as stable as you like.

Pretty much the only good reason for a document to disappear from the Web is that the company which owned the domain name went out of business or can no longer afford to keep the server running. Then why are there so many dangling links in the world?

Part of it is just lack of forethought. Here are some reasons you hear out there: We just reorganized our website to make it better. Do you really feel that the old URIs cannot be kept running?

If so, you chose them very badly. Think of your new ones so that you will be able to keep then running after the next redesign. We have so much material that we can't keep track of what is out of date and what is confidential and what is valid and so we thought we'd better just turn the whole lot off. That I can sympathize with - the W3C went through a period like that, when we had to carefully sift archival material for confidentiality before making the archives public. The solution is forethought - make sure you capture with every document its acceptable distribution, its creation date and ideally its expiry date. Keep this metadata. Well, we found we had to move the files.

Cs Go Zombie Mod Download on this page. This is one of the lamest excuses. A lot of people don't know that servers such as Apache give you a lot of control over a flexible relationship between the URI of an object and where a file which represents it actually is in a file system. Think of the URI space as an abstract space, perfectly organized. St Dupont Lighter Serial Number there. Then, make a mapping onto whatever reality you actually use to implement it. Then, tell your server. You can even write bits of your server to make it just right. John doesn't maintain that file any more, Jane does.

Whatever was that URI doing with John's name in it? It was in his directory? We used to use a cgi script for this and now we use a binary program. There is a crazy notion that pages produced by scripts have to be located in a 'cgibin' or 'cgi' area. This is exposing the mechanism of how you run your server. You change the mechanism (even keeping the content the same ) and whoops - all your URIs change. For example, take the National Science Foundation: NSF Online Documents the main page for starting to look for documents, is clearly not going to be something to trust to being there in a few years.

'cgi-bin' and 'oldbrowse' and '.pl' all point to bits of how-we-do-it-now. By contrast, if you use the page to find a document, you get first an equally bad Report of Working Group on Cryptology and Coding Theory for the document's index page, but the html document itself by contrast is very much better: Looking at this one, the 'pubs/1998' header is going to give any future archive service a good clue that the old 1998 document classification scheme is in progress.

Though in 2098 the document numbers might look different, I can imagine this URI still being valid, and the NSF or whatever carries on the archive not being at all embarrassed about it. I didn't think URLs have to be persistent - that was URNs. This is the probably one of the worst side-effects of the URN discussions.
