The OpenMath standard requires that an OpenMath object starts with the `` tag. However, some OpenMath implementations ( http://www2.macaulay2.com/Macaulay2/doc/Macaulay2-1.15/share/doc/Macaulay2/OpenMath/html/ , https://github.com/OpenMath/py-openmath , https://lurchmath.github.io/openmath-js/site/ ) produce objects without that tag. Hence...

This is the opposite of #300 Let's consider an OpenMath object unknown to Yacas: ``` ``` if this object is converted to Yacas, then a dummy object `yacasform` is created,...

It would be nice if someone with experience of Yacas writes some examples in [https://rosettacode.org/wiki/Category:Yacas](https://rosettacode.org/wiki/Category:Yacas), in order to present the capabilities of Yacas

It would be useful to have the conversion using OpenMath also for polynomials, in particular, I would like to have at least the conversion from OpenMath to Yacas of the...

Please check that the entries about yacas in the wikipedia page [https://en.wikipedia.org/wiki/List_of_computer_algebra_systems](https://en.wikipedia.org/wiki/List_of_computer_algebra_systems) are correct and up-to-date
