I2G Format : Implementation Table


 to be implemented(leave blank)
XXXdoes not exist in DGSinput XXX
xxxonly subelements can be implementedinput xxx
tbdx.y.z.rversion x.y.z.r needs to be tested with the corresponding test caseinput tbd in front
fffx.y.z.rversion x.y.z.r cannot read the element/constraint technicallyinput fff in front (as in fail)
iiix.y.z.rversion x.y.z.r can read the element/constraint technically - without throwing exceptions etc. - so it can at least be ignoredinput iii in front (as in ignored)
?x.y.z.rversion x.y.z.r can read the element/constaint and represent it internally, though maybe with wrong or missing semanticsinput ? in front
!x.y.z.rversion x.y.z.r can read the element/constraint and represent it internally with the correct semanticsinput ! in front


Necessary for support of the intergeo_elements symbols is that a symbol can be interpreted as a concrete instance of a certain type of mathematical object and that a visualization of this instance can be made. Also, an instance of such an object within the software must be available to be exported to (an) OpenMath (compatible) representation of the instance. The parsing of abstract relations to other objects is not necessary for this level of conformance.
