TMX Editor

The online TMX editor provides a standards-compliant space to edit translation memory files. It loads TMX documents, builds an in-memory representation of translation units, and exposes per-unit editing for source and target segments. Inline XML tags are preserved during edits, ensuring structural integrity for CAT workflows. Examples include updating a source term in English for a German target, correcting a mistranslation, or refining terminology across multiple units. The tool supports both standalone edits and batch operations when merging assets from multiple projects, maintaining unique unit IDs and cross-references for auditability.
Conceptually, edits are applied as patches to the TMX tree, with optional diff generation and validation against the TMX 1.4b schema. It supports multiple target languages per unit, search/replace across segments, and round-trip export back to TMX. The design prioritizes data integrity, enabling translators, project managers, and localization engineers to curate memory assets with repeatable results and clear traceability.
Unique value lies in strict TMX compliance, robust tag preservation, and batch merge with conflict handling, plus exportable validation reports. Use cases include glossary-driven updates, segmentation corrections, and harmonization of assets from legacy and new projects. This tool differentiates from generic XML editors by TMX-aware operations, lineage tracking, and outputs tailored to translation workflows.
