I think you have a point here. Probably what it should say is "a link to a Web page is a link to a Web page". > Deep linking is not about depth.

If the component is a Web page, then even if it supports other Web pages, it should be able to stand on its own. If the component is a 'part' of a Web page, such as an image or a style sheet, then this may indeed be a real problem, but I don't think that's what everybody in this thread means when they use the term 'deep linking'. > Owners may object to direct > linking to these components if context, advertisements, or license or > copyright information is lost, Web pages should be self-contained at least to the extent that they contain a link to copyright information if that's deemed necessary. (I am not a lawyer, same applies below!) In general, there's actually no need for copyright information to make something copyrigthed). > if the reference is for an unintended purpose, As long as 'reference' is understood in the sense of textual reference (e.g. "go look over here"), then purpose cannot be a criterion. It may not be the purpose of your website that I disagree with what's written there, but I nevertheless have to be able to say so, or we loose free speech. > or because it drives up hosting costs without returning value. Not all visitors to your Web pages necessarily bring value. That's part of doing business (or anything else) on the Web. > If I have a page on exercises and have an image of a girl demonstrating a > maneuver, and the image is referenced directly for prurient or other > interests, my hosting costs can become significant. If you mean that the image is referenced separate from the Web page it was contained, then that may be a copyright violation. With reference to hosting costs, it may also be theft or fraud. The extreme example would be to refer to another site's one-pixel GIFs (which sure cannot be a copyright violation because there can't be much copyright in such GIFs, but which is clearly bandwith stealing). One possibly salient point with a reference to a Web page is that it's not the the creator of the link that activates it, but the reader. > I am sure you have run > across other examples.

I agree. I think there might be some exceptions and gray areas (e.g. frames), but as a rough approximation, saying that each individual Web page may be safely considered as such a piece, whereas material embedded in such Web pages (images, video, audio, stylesheets) are not such pieces. > Which is more dangerous to the web: recognizing link inequality or having > numerous technologies to assemble contents so they are not easy to reference > directly, but which are also likely to be incompatible with accessibility, > certain browsers or devices, security, internationalization, etc.? I think the distinction between Web pages and auxiliary material, and the distinction between user-triggered links and automatically dereferenced links both make sense and both cut at about the same place.
