Dear all, I discovered OpenMath a while ago and I am trying to figure out how to use it. The documentation looks quite complete in the sense of defining the meaning of OpenMath objects, but what I need is the inverse: find out how to encode a certain formula in OpenMath. In theory, I could study all the content dictionaries, but I'd probably give up before completing that task.
So what I am looking for is either a tutorial, or at least a list of examples. I don't need anything particularly exotic, but I don't even see immediately how to express something like "a sum over all pairs of indices". Version 2.0 of the OpenMath standard refers to "OpenMath primer" at http://www.openmath.org/standard/primer/, but the contents are a bit disappointing. For a bit of background information, I intend to use OpenMath for describing potential energies in molecular modelling. I am working on a data model for computational chemistry (http://mosaic-data-model.github.io/), which is to molecular modelling what OpenMath is to maths: a data model with multiple encodings designed for exchanging data between programs.
