I may have missed it, but a missing element in the thread so far seems to be economics. I think some people are assuming that information will remain free, and therefore "universally" accessible (e.g., accessible to 8-year-olds) indefinitely. The existing situation will change dramatically as soon as viable commerce protocols are deployed widely, and this *will* happen within a couple of years. Think in terms your 8-year-old carrying a couple of bucks for school lunch and a couple of digibucks on the PCMCIA smart card for commercial-free Power Rangers (or whatever) during recess. Your school taxes will pay the Internet/NII access provider, but you'll still have to pay for information and entertainment ("infotainment"?) services incrementally. Obviously, these smart cards will need to carry ID and cryptographic keys as well as digibucks if they are to be remotely useful. Cards like this are already appearing, minus the digibucks --- check out the NSA's FORTEZZA card for an example. Most, if not all, of the free sexy Internet stuff (digitized images, mostly, it seems) causing some frantic pre-election-year posturing in the U.S. Congress will probably no longer be free, or even cheap, assuming only trustworthy commerce protocols with strong (possibly card-based) authentication backing them up. In essence, many kids could quickly be priced out of the "adult" market with no further action on our part now. I won't defend this claim any further, but I feel it's a factor we need to keep in mind. Getting back to the thread, though, I'll have to vote for an HTTP header for rating information (to support "KidCode" or whatever) primarily because the "rating" of a document, whether it's for sexual content, violence, use of "adult" language, military security, etc, is not properly part of the document itself, but is a highly context- dependent judgement about the document. It's tempting to say this judgement is also "subjective", but this is not always true. Clearly, in some cases you could embed some hints about various content-related aspects of the document as markup of some kind (even as comments) but you'd normally be inserting this markup long before delivering the document to a consumer -- and the details of delivery can be an important part of the context for deciding on a rating. For example, as we know, some southern U.S. states have markedly more conservative "community standards" than, say, Los Angeles, California. What's considered "PG" in some communities is fodder for prosecution and prison in others. Some servers may choose to apply varying standards to content rating, for reasons having nothing to do with assumed delivery destinations. You simply can't account for wild inconsistencies in "community standards" beforehand, and this seems to reduce the status of embedded content ratings to hints. How a server arrives at a rating can't be part of our protocol spec, and we can't even anticipate the complete set of possibilities for ratings themselves, but we need to allow for a content-rating header and have a loose spec formalized (e.g., "7-bit ASCII text...") for its argument field(s) and what the default assumptions to make should be when the header is absent, out-of-spec or unintelligible. The argument field(s) for the header could be something you solicit from publishers or try to adopt from known standard practice (if any) at the presumed destination site for the delivery. For our immediate purpose, though, we need only provide the space for the arguments without further specifying them. I completely disagree with the notion that "unrated" implies anything stronger than simply "not rated by anyone". We really can't get into a position where we'd effectively force every author and HTTP server to explicitly rate the content of every miserable little embedded image and every document. The grounds for rejecting material for viewing at the client have to be concrete, based on the unambiguous presence of a restriction, not the mere absence of one. Servers could themselves be rated, of course, rather than documents. This is not something supported in the existing infrastructure, but it wouldn't be hard to add. I doubt this would eliminate the demand for content rating of some kind. - Bede McCall <bede@mitre.org> The MITRE Corporation Tel: (617) 271-2839 Bedford, Massachusetts FAX: (617) 271-2423
