Details

The CLDR data import subsystem in Babel is designed to efficiently download, validate, process, and persist CLDR (Common Locale Data Repository) data.

DownloadOrchestrator

Manages the process of downloading CLDR data archives from external sources, ensuring the raw data is available for processing. This is critical for the "Data-Driven" nature of the library.

Related Classes/Methods:

• download_latest_cldr:10-100

FileValidator

Ensures the integrity and correct format of the downloaded CLDR data files before further processing, acting as a gatekeeper for data quality.

Related Classes/Methods:

• validate_cldr_data:100-150

ImportInitiator

Serves as the main entry point for triggering the CLDR data import and conversion workflow, orchestrating the overall data pipeline.

Related Classes/Methods:

• main

ConversionChecker

Determines if a new conversion of CLDR data is necessary by comparing timestamps or versions of existing data, optimizing the process by avoiding redundant work.

Related Classes/Methods:

• check_conversion_needed:150-200

DataProcessor

Orchestrates the overall conversion of raw CLDR XML data into Babel's structured internal data, coordinating both global and locale-specific parsing. This is the core transformation engine.

Related Classes/Methods:

• process_cldr_data:200-300

LocaleDataDispatcher

Manages and dispatches the parsing of various categories of locale-specific CLDR data (e.g., display names, calendar data) to specialized parsers, embodying the "Functional Decomposition" pattern for locale data.

Related Classes/Methods:

• parse_locale_data:300-400

DataParsers

A collection of specialized functions, each dedicated to extracting and transforming a particular type of CLDR data from the XML structure into Babel's internal format. These components implement the "Data/Logic Separation" by focusing solely on parsing logic.

Related Classes/Methods:

• parse_locale_display_names:526-538
• parse_calendar_months:622-637
• parse_number_symbols:769-780
• parse_currency_formats:950-987

DataWriter

Persists the fully processed and converted CLDR data into the appropriate output files or internal data structures for Babel's runtime use, completing the data pipeline.

Related Classes/Methods:

• write_data:153-160

XMLTextExtractor

Utility function for extracting text from XML elements.

Related Classes/Methods:

• extract_text:50-60

ElementSkipper

Utility function for determining if an XML element should be ignored during parsing.

Related Classes/Methods:

• skip_element:60-70
