SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires lxml, and includes scripts (resource) components.

What problem does it solve?

1C XDTO packages are stored in a binary-like Package.bin format that is hard to read, edit, or share. This Skill converts an existing XDTO package into a standard, valid XML Schema (XSD) so you can review the full structure, hand it to a counterparty, or migrate the package to another configuration.

Core Features & Use Cases

  • XDTO to XSD conversion: Reads Ext/Package.bin (accepting a package directory, the Package.bin file, or the metadata .xml path) and emits a valid XML Schema preserving facets, unions, lists, and complex types.
  • Lossless round-trip: Metadata properties (name, synonym, comment) are exported into xs:annotation/xs:appinfo, and XSD-inexpressible details are kept as xdto: mirror attributes, so /xdto-compile -Force can rebuild the package without losses.
  • Use Case: You need to send the exchange schema of the 'ОбменСБанком' package to a bank's integration team. Run the decompile script with -OutFile bank.xsd and share the resulting valid XSD, which unlike the Designer's built-in export preserves nillable on attribute properties.

Quick Start

Ask the AI to decompile the XDTO package at src/XDTOPackages/ОбменСБанком into an XSD schema file.

Frequently Asked Questions about xdto-decompile

FAQPage Schema
How do I export a 1C XDTO package to an XSD schema?▼

Run the xdto-decompile script with -PackagePath pointing to the package directory, its Ext/Package.bin file, or the metadata .xml file. Add -OutFile to write the schema to a UTF-8 file, otherwise the XSD is printed to stdout.

How to migrate an XDTO package to another 1C configuration?▼

Decompile the package to XSD, change the targetNamespace (and the matching xmlns declaration used as a prefix), then rebuild it with /xdto-compile using -Name for the new package. Name and synonym are set by compile flags, not edited inside the schema.

Does the exported XSD lose data compared to the 1C Designer export?▼

No. The generated schema is valid and lossless: the Designer's built-in XML schema export loses nillable on attribute properties, while this tool preserves such details as xdto: mirror attributes that validators safely ignore.

What are the xdto: prefixed attributes in the generated schema?▼

They record details XML Schema cannot express, such as nillable on attributes or explicit variety markers. The schema remains valid since validators ignore unknown attributes, and /xdto-compile uses them to rebuild the package without losses.

When should I use xdto-decompile instead of xdto-edit or xdto-info?▼

Use decompile when the schema must be changed broadly, studied in full, versioned, or sent to a counterparty. For a single property fix use /xdto-edit, and for a summary of what to assign use /xdto-info.
