In reading the draft finding at http://www.textuality.com/tag/DeepLinking.html , I have two suggestions: 1. I think there is a concept a stake that is not sufficiently brought to the forefront. In particular, the difference between IDENTIFYING something and ACCESSING that thing. 2. I would suggest a library/book analogy for deep linking. I would suggest adding (or merging) the following description to your draft finding: -------- A URL is simply a NAME for a particular document on the Web. It is NOT the same as the document itself. Consequently, there are two very different acts that need to be clearly distinguished: (1) The act of IDENTIFYING, REFERRING TO, or TALKING ABOUT a document; versus (2) the act of ACCESSING, OBTAINING or COPYING that document. A "home page" URL is analogous to the physical address of a library. A "deeply linked" URL is analogous to the physical address of a particular book within that library. Both are used to unambiguously identify something and indicate where it can be found. For example, I can unambiguously identify a particular library by writing: "Somerville Public Library, 75 Highland Ave, Somerville MA, USA" This library address is analogous to a "home page" URL. It allows me to unambiguously identify that library when I am talking to you, so that we are certain we are discussing the same library. It also tells you where to find that library. However, IDENTIFYING the library is NOT the same as ACCESSING it. Your possession of the library address does NOT necessarily give you the right to ACCESS it. (Indeed, you might be required to hold a valid library card for that particular library in order to access it.) I can also unambiguously identify a particular book WITHIN that library by writing: "The Selfish Gene, by Richard Dawkins, Call number 591.35/DA, Somerville Public Library, 75 Highland Ave, Somerville MA, USA" This is analogous to a "deeply linked" URL. Again, it allows us to unambiguously discuss that particular book, and it tells you where you can find that particular book. However, your possession of the book address does NOT necessarily give you the right to ACCESS, OBTAIN or COPY that book. ANYONE should be able to use a URL to IDENTIFY, REFER TO, or TALK ABOUT any document on the Web, even if that document is deeply nested within a particular web site. However, this does NOT mean that everyone should have the right to ACCESS, OBTAIN or COPY that document. -- David Booth W3C Fellow / Hewlett-Packard Telephone: +1.617.253.1273
