IDLn

Could you clarify what IDLn stands for and the domain it belongs to? The acronym could refer to different concepts across fields such as computing, biology, linguistics, or others. If you provide the intended meaning or field (for example, a specific technology, organization, or theory), I can draft a concise, neutral wiki-style article in plain text under 300 words. If you’d like a fictional or hypothetical entry, I can create a plausible, self-contained stub as well.
