Rotan, well put. Heuristics are IMO an essential aspect of dealing with a rapidly evolving web, which exceeds the ability of even the most farseeing content/protocol designers in W3C & IETF to predict. Since the start of the mobile market it has been my company's business as a service provider (as Rotan puts it) to "make use of mankind's technological advances, and adapt the delivery where possible". We do look forward to device/user-agent advances that allow us to reduce content transformation requirements, and the related costs. But we have to serve this evolving market where the realities of services and implementations are not always neatly delimited by specifications. Being able to use heuristics as well-tested triggers for invoking transformation will be essential for the forseeable future, especially as devices are not evolving quite as fast as those on the leading edge would think, and emerging markets are creating new spaces for limited-capability devices. In terms of the general role of CT proxies for content adaptation/repurposing, Rotan's other remarks about offering content for the purpose of consumption and expanding the audience are well worth thinking about. What would the Web be right now, if content (created by Content Providers and Users) was not very freely repurposed all over the place, repackaged and delivered in ever-innovative ways? Certainly copyright etc is crucial to consider where possible, and semantic expression of copyrights and editrights (a new term, but to the point) are good to develop, but in the meantime are we to halt innovation or restrain accessibility? By addressing these guidelines in the narrower scope of CT proxies we are likely helping to break ground on addressing some of the larger issues of Web content use.

[Guidelines for Web Content Transformation Proxies] The Web seems to be the one place in the world of publishing where there is an overwhelming (and incorrect) believe by all except the content originators that copyright doesn't exist. The problems of unsolicited derivative works, rampant plagiarism, phishing and the growing dependence on network security as the backbone of our digital society, were not envisaged at the time when the simplistic transcoding proxy examples were devised. Tom may have just pointed to the genesis of the problem, emphasising the chasm between then and now. Back then it all seemed so simple and innocent. Today is different, and unless we find a way to establish boundaries and police our activities, we could descend into chaos. Eventually, most of our intellectual output will be Web based, supplanting the dominance of paper that has held sway for countless generations. It would be a sad time for humanity if this transition to the Web was accompanied by a loss of recognition for those who create the content in the first place. I have long said that it is necessary to find the right balance. Respect for what the author intended (where known, or knowable), what the reader prefers (including more/less capabilities) and for those whose role is to convey the content from author to reader. In the absence of any evidence from the author with respect to publication intentions, one can reasonably assume that the content is made Web-accessible merely for the purpose of consumption, without regard to how it is consumed. As the author increases the effort, such as taking steps to ensure it is effective in certain delivery contexts, there should be corresponding respect for fidelity to this effort. Of course, a consumer of such carefully crafted content may still be incapable of benefitting from the author's efforts due to certain limitations (human incapacity being just one example), so the fair thing to do in this case is make use of mankind's technological advances, and adapt the delivery where possible. Most authors would have no problem with this. Indeed they would applaud the expanded audience. Luca, I believe, has been railing against the possibility that we, the Internet/Web industry, would countenance an absence of fairness and respect for the wishes of authors and the balancing needs of consumers. The presence, and actions, of an intermediate actor in the interaction between author and consumer is one of great power. Potentially power for considerable good, but equally power that can be abused. The W3C, and others, have recognised the significance of this problem and it is good to see that some progress is being made (though much more needs to be done). However, I am dismayed that the argument spends so much of its time mired in technical nuance. The real issue is in the greater sphere of society, the role of creativity, the respect for that which is created, and the recognition of the need to share creations with everyone irrespective of their contextual circumstances (device capabilities being just one tiny facet of this). I am also dismayed to see throw-away references, such as the one-liner from Tom, which could be so much better if their relevance to the debate were elaborated when introduced. And my dismay is compounded by unnecessary "name calling" that peppers the environment, a temptation that regrettably takes hold of Luca from time to time. I understand your passion, and share many of your concerns, though I would never express them in such florid ways. So, to the point in question. A non-normative list of mobile heuristics might be a practical way of showing a would-be intermediate transcoder how to determine if content visible on the Web was intended to be delivered to specific contexts in specific ways. My concern would be that this list would be considered definitive, and that there would be some providers of transcoding solutions who would think their duty to authors was complete so long as the list was adhered to. The real point is that transcoders should respect all parties, and continue to improve upon their means of analysis. Only when they have exhausted such analysis should they take the position that the content they are observing is open to transformation, and even then, they should only execute such transformations where the actual delivery context demands it. Transformation has a role, and this includes intermediates, and is to be welcomed when it serves the greater good. Absolutist positions are unwelcome. If we did not allow some flexibility in representations, society would still be reading the ancient texts on goatskin, we'd still be listening to the Beatles on vinyl, and the only place to see the works of the great artists would be in the museums. Personally, I like the idea of reading Shakespeare on my e-book while listening to the MP3 version of "All You Need Is Love"... ---Rotan. Disclosure: We are providers of a server-side transformation solution, which can also act as a proxy but only under the direct control of the content author. We do not provide indiscriminate transformation proxy solutions, and those that are already deployed by other vendors have a tendency to disrupt the legitimate business of our customers who are making huge efforts to delivery excellent mobile experiences via our products. We accept that intermediate content transformation solutions will likely be here to stay, and we respect the legitimate role they can play, so long as there is fairness and respect for all parties. ____________________________ Dr Rotan Hanrahan Chief Innovations Architect Mobileaware Ltd 4 St Catherines Lane West The Digital Hub Dublin 8, Ireland E: rotan.hanrahan@mobileaware.com W: www.MobileAware.com CONFIDENTIALITY NOTICE This e-mail message and all documents that accompany it are intended only for the use of the individual or entity to which addressed and may contain privileged or confidential information.

[Guidelines for Web Content Transformation Proxies] toxic nonsense, Tom. The same kind which got you ejected from WMLProgramming in the end. The fact that a specification mentions (as part of an example!) that some proxies may save some bandwidth (in 1999's Internet) by reducing the size of pictures is *so* distant from what we are seeing today with transcoders (producing derivative work of content they have no rights to, removing essential headers, adding banners and toolbars, breaking HTTPS) that I wonder if you are simply trying to make fun of everyone here. Either that or you deserve to go work for Novarra!
