ESML

Esml is an acronym that appears in several domain-specific contexts, and there is no single, universally accepted definition. Because different communities reuse the same letters for different concepts, the exact meaning of Esml is usually inferred from context, field, and accompanying documentation.

In environmental informatics and Earth-system modelling contexts, Esml has been used to denote an Earth System Markup Language. In these discussions, ESML is presented as a lightweight markup approach intended to help represent, exchange, and annotate data produced by climate, weather, or ecological models and observations. The emphasis is on interoperability and metadata-rich representations, though no single standard has achieved universal adoption.

In software engineering and data analytics discussions, Esml is sometimes used to describe an Extensible Spreadsheet Modeling Language, a proposed framework for encoding spreadsheet-based models in a machine-readable form. Proponents describe Esml as a way to separate model logic from presentation, enabling validation, versioning, and automated transformations.

Other uses exist in education technology, linguistics, or project names, but these are less widely documented. Because of the term’s ambiguity, readers should consult the specific source where Esml is encountered to determine the intended meaning.
