# OpenMath Mathematical Markup Languages Data Formats

OpenMath is an emerging standard for representing mathematical objects with their semantics, allowing them to be exchanged between computer programs, stored in databases, or published on the worldwide web. In contrast to MathML, which deals principally with the presentation of mathematical objects, OpenMath is solely concerned with their semantic meaning or content.
