2Gtl

2Gtl, sometimes written 2GTL, is an acronym that has appeared in different domains to denote different concepts. There is no single universally recognized definition.

In technology and computing, 2Gtl has been used as an abbreviation for Two-Generation Template Language, a proposed domain-specific language intended to express transformations between two data templates. The concept extends ideas from template languages and graph transformation by enabling bidirectional or two-stage transformations. Key characteristics described include rule-based syntax, pattern matching, and modular composition. No widely implemented standard exists; the term remains largely theoretical and is not widely adopted outside speculative literature.

In biology and genetics, 2Gtl may be used as a placeholder label for a hypothetical second-generation trait locus (Gtl stands for gene/trait locus). It is not a real, codified gene name; practitioners typically replace it with context-specific nomenclature.

In culture and media, 2Gtl has also appeared as the name of fictional organizations or products in short stories or media; such uses are standalone and not related to the technical uses above.

Because 2Gtl is context-dependent, consult domain-specific sources to determine the intended meaning in any given reference. See also GTL, template languages, and gene/trait locus nomenclature for related concepts.
