No. Actually, I belong to that particular community of practice whose job it is to explain to others exactly what English words mean, so it would be exceedingly unlikely for me to have confused those words. You may not have known that, of course, so your use of this rhetorical tactic may be understandable. >> I think MathML works, and I think it's successful in the areas it's >> useful >> for.

No need for addressing your "market penetration" > again. It all boils down to our difference in opinion about what it means for MathML to be considered "successful". Let's agree to disagree. That way, you can allow words to mean whatever you'd like them to mean. >>> Fortunately, not all people has so great views on MathML like you; just >>> some thougts from the SBML community: >> >> My views of MathML are not that favorable.

What exactly would I understand by > your "it *IS* the standard"? There are at least two ways to understand what I meant by that: (a) The W3C has exactly one standard for representing math, and that's MathML. Like you, I choose to orient myself largely around the W3C (as opposed to ANSI or ISO or whatever). There's a particular reason for that in my personal case: the W3C gets stuff done in finite time. I was a consultant to the original SGML committee back when the earth was still cooling, and I argued fruitlessly for decades to get a standard, stripped-down but still SGMLesque language for hierarchical data representation and transfer. It was the W3C that ultimately caused XML to be successful, and it will be the W3C that will ultimately cause most current and future IT standards to be successful. (b) The computational biology community that uses CellML and SBML (two standards for representing physiological and metabolic networks) has adopted MathML as their standard for representing the mathematical bits (e.g. rate laws in reaction kinetics). > Any case ISO-12083 *IS* an previous international standard (MathML is > technically a w3c recommendation not a standard because w3c is not a > standards body) and I do not see you promiting its usage, why? What are > your reasons? Because I don't like ISO, and do not wish to place any bets on them. This is a business decision on my part, you see -- not an academic decision, much less an aesthetic one. >> It's not surprising that people in the SBML community would say the same >> thing. Great minds think alike, after all. > > Let us wait and see if the introduction of MathML into SBML was fortunate > or not :-) Do not forget that great minds can make mistakes too. We already know that it was fortunate. I can build a tool to plug numbers into content MathML expressions that will work with both SBML and CellML, and with anything else that uses MathML. I can build a tool to turn MathML-expressed systems of differential equations into a discrete event graph for simulation without needing to come up with my own ad hoc language for representing the equations. >>> And MathML is so succesfull in the SBML community that last years was >>> launched a thread in the SBML site called "Complementary Alternative to >>> MathML Needed".

Why are online applications more important than others? You can't say that MathML is unsuccessful across the board just because it's not found as much use in your favorite horizontal than in others. (Well, actually, *you* can say that, and often do. But most reasonable people would not.) >> Success of a product doesn't mean that I like it particularly well, that >> I don't think it could or should be improved, or that there are no >> conceivable alternatives that would better serve my purposes.

What problem is that? > A thing irritating me is the only-way concept you (and others) are trying > to promote without real rationale for leaving alternatives. When have I ever tried to promote any kind of only-way concept with respect to MathML? I'm sure you must have misunderstood me. > How expressed many times here if MathML is so good and so popular and so > succesfull, nobody would become interested in alternatives, therefore you > would not worry about my writtings after all. I worry about your writings because you do not take a careful and reasoned approach to making your points, because your writings are very difficult to understand completely and because you spend a lot of bandwidth fishing for debating points with clever nonsequitur or decontextualized flippancy. But I worry about global warming and peace in the Middle East, too, and there's not all that much that I can do about those problems, either. >>>> What do you mean by "content" and "meaning" such that content MathML >>>> is >>>> about the one but not about the other?

You already knew better. Not at all.

There are plenty of people who will remain unconvinced no matter how much evidence of whatever quality is placed at their feet. Although I feel sorry for these people, I can't take the time to bring them on board at any cost. They'll have to catch up later. >>> Time?

You claims MathML is succesfull in > "market terms" and you are promoting it without solid technical basis. When have I ever promoted MathML in any way? All I've done is disagree with you when you've claimed incorrectly that MathML is unsuccessful in every way (or equally incorrectly, in all ways but one). Never in my life have I ever suggested to anybody that they should use MathML instead of some alternative. My decisions to use MathML are my own, but you don't seem to want to leave me to them: you tell me I've made the wrong decision because you think I don't have the technical wherewithal to make the correct decision, which in your mind must always necessarily exclude MathML. Right? > You also find CSS rendering of no interest I find CSS rendering of no interest *to me*. What's wrong with that? > and even initially claimed that rendering of math would be addressed in > another part Another part of what? What do you think I initially claimed? > (even claimed that math on the web posts would be submitted outside this > list!) I claimed that it was rhetorically ineffective to post anti-MathML polemic on this MathML-aligned list. And so it is. I did make the suggestion that your posts might be better suited to the WebMath list, but it turned out that the owner of that list doesn't want us there either. > You also claim that you are using MathML because is the "standard". Yes. What should I use for embedded math in CellML and SBML models instead of MathML, in your opinion? > After all one of advantages of using a "standard" is many people can > write and interchange code in a unified way, no? Yes. > How is possible that you can maintain that MathML is working and is > succesfull in function of "objective data" but cannot even encode > something so simple as (a+b) in content or parallel MathML. What makes you think I cannot encode (a+b) in MathML? I choose not to allow myself to be patronized, but that's a different matter altogether. > Are your claims about success and working so political and marketing > based as youir thoughts about Windows or Beta or there is real stuff > beyond your thoughts? I have to work for a living, so politics and marketing are "real stuff" for me. Academic and aesthetic vagaries, on the other hand, don't pay the bills. YMMV. > I know claims from other people (including MathML folks); i agree with > some and disagree with others but you sound more as waporware to me. If you think my work is vaporware, I don't have a problem with that. BTW, how many employees are there at the Center for Canonical Science? Is it all housed in one building, or do you have a proper research campus? > It is time also for a MathML 3 spec, I have proposed some basic ideas for > the new spec (I do not know if will be accepted or rejected). You often > claim how good MathML would be if you had done! No. I claimed that MathML would have been much better *FOR MY PURPOSES* if I had designed it myself. I also said that that would precisely *NOT* entail that MathML would necessarily be any better for anybody else's purposes, and that that's the rub. The WG's task was to come up with something that would do reasonably well for a reasonable variety of applications, and it's obvious (from the objective measures you deny) that they've achieved that. > If I remember correctly Patrick encouraged you to post here some ideas > for MathML 3 discussion but your messages continue lacking technical > stuff in an alarming way. As I told Patrick, I will provide MathML-related feedback from the computational biology arena as I encounter or create it. For now, I'm in the process of pouring the content MathML specs into a Python expression cruncher so that I have it in place when I'm ready to provide CellML and SBML interfaces to my simulation engine. For all of that, we're talking late this year and into next year, not this week and next. Most of my work with the simulation platform at the moment is actually in cognitive science (computational linguistics), which is where I have the most enthusiastic collaborators. >> If you have examples that cannot be encoded correctly in content MathML >> by anybody because the language is inadequate, then I'm certainly not >> the person you need to talk to. > > I agree with you.

That traditional definition no longer applies, however. XML is a markup system. RDF and OWL can be expressed in XML. RDF and OWL files therefore constitute "markup". There's no prima facie need to care about presentation issues for RDF and OWL files. Nobody think's it's a mistake (much less a common mistake) to have developed RDF and OWL without giving much thought to presentation. Therefore, your blockquote is misguided, misstated or misquoted. >>> It is not how you think that one can design a content markup for people >>> who is not interested in rendering issues and next one design a >>> presentational layer for rendering. >> >> How do you know? Have you ever tried to design a content markup scheme >> for math without regard for of rendering issues? > > After many posts I can begin to see your point clearly now ;-) Perhaps. If you're starting to see that I think content MathML has more in common with RDF and OWL than with, say, HTML or Postscript, then you might be right. -- Mark Mark P.
