TL->CMC: Can you comment about this? Thanks! >- the file uses openoffice' own dtd; why not using the mathml2.0 dtd >from w3c? Well the short of it is that mathml 2 didn't exist when I started. And there was a requirement from our xml group that everything be inside the openoffice xml namespace so the dtd used is the mathml 1.01 dtd with namespaces added to it. >- for various symbols like integrals, sums, etc, why not use the >entities defined by w3c? A number of converter tools rely on these >symbols I'd love to as well, but on import entities are replaced with their equivalent unicode codepoints by the underlying xml library before they get to the mathml parser, and on export a substitution back to entities is similiar not in the mathml parsers power at present. This is something that would need to be discussed with our xml people. >- why enclosing the full formula into a <math:semantics> element? this >makes it difficult to handle the file You can only edit equations in starmath through its own UI equation language like latex/ezmath. To retain this text the semantics element is needed. If the text changed, even for trivial whitespace changes or replacing one equation text with another equivalent one, then user's would have a format where what they save is what they see on load. There is certainly an argument that the semantics tag should be broken down to seperate tags which surround invididual elements to closer denote what matches to what. But it is an unavoidable requirement of the current starmath system as far as I can see that the original user entered text be retained somewhere. And that is what the semantics element is specifically in the mathml spec for, so that's why it is in use. >Note that having a free tools to create mathml formulae is an >incredibly valuable tool for the community, so it would really be >worth improve it toward mathml 2 (and announce this feature more >widely!) It would indeed be very nice, but a good deal of work. So it don't be possible to tackle this in the 1.1 beta timeframe. So I'll target this for OOo 2.0 and revisit it. Reopen to reassign cmc->bh: A request to support MathML 2.0 for import/export. Hello Caolan, I leave this issue on the OO.o 2.0 flag. Could you please take this one to your ownership for implementation. Thank you. cmc->bh/ama: Ah, are we sure about this?.. this would be a load of work, there are loads of features in mathml2.0 which are not supported by our starmath at all, and some which are likely not to map well to the new mathml 2.0 without a lot of effort on our side. I'd be reluctant to take on board such an open ended 2.0 task given all the other existing .doc and .rtf work which we are also trying to do for this target. I see this mathml 2.0 stuff as a desirable feature, rather than a must have. Ok, in consideration, that it is no keyfeature for Q, I take this on target 'Office later'. From 2003-10-21, MathML 2.0 Second Edition is a W3C recommandation. Issue 10284 and Issue 13657 are not duplicated ? . OASIS Open Document Format for Office Applications (OpenDocument) Version 1.2 Section 1.3 lists Mathematical Markup Language (MathML) Version 2.0 (Second Edition), http://www.w3.org/TR/2003/REC-MathML2-20031021/, W3C, 2003. as a Normative Reference. Support for MathML 2.0 is not included Apache OpenOffice. A post from the Apache OpenOffice Community Forum today indicates a need/desire by users who write "real math": http://forum.openoffice.org/en/forum/viewtopic.php?f=12&t=59659&sid=7207fef996b8457da5df8b4068e00ff1#p264087 |
