ISO to PKG converter

About This Tool

The converter translates ISO-formatted identifiers into PKG metadata fields used by packaging workflows. It accepts two inputs: an ISO value (date/time, code, or identifier) and a target PKG schema or field. It performs strict parsing against common ISO 8601 date-time strings, ISO language and region codes, and identifier formats, then maps them to equivalent PKG attributes such as timestamp, locale, or identifier. For example, 2024-08-11T15:30:00Z becomes a PKG timestamp value 20240811T153000Z, and en-US becomes locale en_US. Outputs are deterministic and reversible within the defined mapping rules, enabling automation with CI/CD pipelines.
Core logic processes inputs in stages: normalization, validation, and emission. Normalization converts disparate ISO representations into canonical forms. Validation enforces range and format rules (dates within allowed windows, codes from the supported ISO sets). Emission formats the PKG metadata block exactly, applying field names and value patterns required by the target PKG schema. Optional advanced features include handling multiple ISO inputs in a single pass, batch processing, and custom field mappings via a config map. Practical use cases include converting a release date and locale from ISO formats for a package manifest or aligning legacy identifiers with modern PKG systems.
Unique value lies in deterministic crosswalks, offline-ready logic, and explicit error handling for unrecognized inputs. Developers, release managers, and build engineers benefit from reduced manual mapping, faster pipelines, and fewer inconsistencies between ISO standards and PKG metadata. This tool targets unit tests, data migrations, and CI pipelines requiring reproducible conversions.
