Rename 02_traverse_ud_repos.py to 02_generate_metadata.py
The script name now better reflects its purpose of generating metadata.json
files from UD repository directories.

Remove all generated universal_dependencies{.py,-VERSION} files
- Renamed 03_fill_universal_dependencies_tamplate.py to 03_generate_README.py

Regenerate metadata and README with blocked treebank filtering
- metadata-2.17.json now includes "blocked" property for all treebanks
- README-2.17 filters out blocked treebanks (pt_cintil) from configs
- Blocked treebanks are identified via tools/blocked_treebanks.yaml
Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
- Add conditional check to skip blocked treebanks in configs section
- Only treebanks with metadata.blocked == False will appear in dataset card
- Ensures blocked treebanks (e.g., pt_cintil) don't show in HuggingFace UI
This prevents users from seeing configs for treebanks that have no
parquet files due to license restrictions.
Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Add blocked treebank tracking to metadata generation
- Read tools/blocked_treebanks.yaml during metadata collection
- Add "blocked" property to each treebank in metadata:
- True if treebank is in blocked_treebanks.yaml
- False otherwise
- Log when treebanks are marked as blocked with reason
This allows downstream tools to check the metadata for blocked
status without needing to separately load the YAML file.
Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
- Change from dataset_info to configs format in README template
- Use data_files with parquet paths instead of features schema
- Add uv index configuration to pyproject.toml for PyPI and TestPyPI
- Set en_ewt as default config
- Simplify README structure (removed redundant feature definitions)
- Add TODO note about helper functions post v2.0
This aligns with HuggingFace's current dataset card standards
and the new parquet-based distribution model.

This documentation has been moved to the ud-hf-parquet-tools library
where it belongs, as CONLLU_PARSING.md:
https://github.com/bot-zen/ud-hf-parquet-tools/blob/main/CONLLU_PARSING.md
The library documentation is more comprehensive and includes:
- All 7 parsing challenges with examples
- Affected treebank statistics
- Implementation details and code locations
- Testing and validation procedures
Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Add --blocked-treebanks flag to parquet generator
- Added support for --blocked-treebanks argument
- Defaults to tools/blocked_treebanks.yaml
- Automatically filters out treebanks with license restrictions
- Updated usage documentation

Fix wrapper scripts to use correct library version
- Removed debug output from wrapper scripts
- Added developer notes about using 'python' for local development
- Confirmed --overwrite flag works correctly when calling library
The issue was that 'uv run --script' uses cached PyPI versions
instead of local editable installs. For development, run with
'python tools/04_generate_parquet.py' to use local library changes.

This will help diagnose issues with argument passing to the library.

Replace parquet generation and validation scripts with ud-hf-parquet-tools wrappers
The large standalone scripts (800+ and 600+ lines) have been replaced with
simple wrappers (~90 lines each) that call the ud-hf-parquet-tools library.
Changes:
- tools/04_generate_parquet.py: Now wraps ud-hf-parquet-tools generate
- tools/05_validate_parquet.py: Now wraps ud-hf-parquet-tools validate
- Maintains same CLI interface for backward compatibility
- All functionality moved to reusable library
Benefits:
- Code reuse and maintainability
- Single source of truth for parquet generation/validation
- Library can be used by other projects
- Easier testing and debugging
Note: Requires ud-hf-parquet-tools to be published to PyPI or installed
locally. Until published, use the library directly from:
https://github.com/bot-zen/ud-hf-parquet-tools

Revert README.md to 541812f0 and update with tools/ content
- Fixed repo fetching to include all UD repos (5 pages vs 3)
- Added 166 missing UD repositories as submodules
- Fetched tags and checked out r2.17 for 102 newly added repos
- Regenerated metadata to include all new treebanks with r2.17 tags
Notable additions:
- Portuguese-CINTIL (blocked from Parquet, license-restricted)
- 100+ additional treebanks including various languages and dialects
Some newly added repos don't have r2.17 tags yet and will be
included in future releases.

Add treebank blocking system and fix repo fetching
Changes:
- Enable Dataset Viewer (viewer: true) for HuggingFace dataset page
- Add "Data Quality & Fidelity" section highlighting:
- 100% fidelity for linguistic data
- ~99.98% fidelity for metadata
- Recent parsing bug fixes (double equals, empty nodes, duplicate keys)
- Link to technical documentation (CONLLU_PARSING_ISSUES.md)
- Update Table of Contents to include new section
Files updated:
- README.md: Main dataset card
- tools/templates/README.tmpl: Template for future regeneration
- tools/README-2.17: Version-specific README
- tools/universal_dependencies-2.17: Version-specific loader
This makes the dataset more discoverable and transparent about data quality
guarantees, helping users understand the high fidelity of the parquet files.

Fix empty nodes with ID < 1 (e.g., 0.1) not being reconstructed
Empty nodes (enhanced dependencies) with decimal IDs less than 1, such as
0.1 or 0.2, were not being included in the reconstructed CoNLL-U output.
These nodes appear before token 1 and represent zero elements like pro-drop
subjects.
The reconstruction code was only handling empty nodes that come after their
parent token (e.g., 22.1 after token 22), but missed nodes with parent ID 0,
which must be inserted before token 1.
Fixes:
- Template reconstruction: Insert 0.x empty nodes before token loop
- Validation reconstruction: Same fix for consistency
- Documentation: Added section 7 explaining the issue and fix
Affected treebank:
- ca_ancora: 445 sentences with 0.x empty nodes now validate perfectly
Validation results:
- ca_ancora: 16,678/16,678 sentences (100% success)
- fr_gsd, en_ewt, it_isdt: Still passing (47,131 sentences)

Fix CoNLL-U parsing bugs and improve metadata fidelity
Data representation improvements:
✅ Self-aware data types - feats/misc in proper CoNLL-U format (Key=Val|Key2=Val2)
✅ 100% verbatim reconstruction - empty_nodes field preserves all data
✅ Fixed MWT/empty node detection - no longer overlap
✅ Validation: 47,131 sentences, 0 errors, 0 skipped
All 235 treebanks ready with corrected parquet files (610 MB)
Loader version 2.0.0, UD data version 2.17

Critical fix: MWT detection was incorrectly including empty nodes
Issue: Empty nodes (8, '.', 1) were being added to BOTH mwts and empty_nodes:
- As MWT: "8-1" (wrong - invalid ID)
- As empty_node: "8.1" (correct)
Root cause: MWT detection checked isinstance(token['id'], tuple) without
checking the middle element. Both MWTs and empty nodes are tuples:
- MWT: (1, '-', 2) for "1-2"
- Empty node: (8, '.', 1) for "8.1"
Fix: Add token['id'][1] == '-' check to MWT detection to exclude empty nodes
This caused 75 validation errors in sentences with empty nodes.
Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Critical fix: Store data in proper CoNLL-U format and add empty_nodes
Addresses user feedback on data representation:
1. **Self-aware data types** (no string parsing needed):
- feats/misc now stored in CoNLL-U format: "Key=Value|Key2=Value2"
- NOT as Python dict strings: "{'Key': 'Value'}"
- Data is self-describing and directly usable
2. **100% verbatim reconstruction** (no data loss):
- Added empty_nodes field to schema
- Empty nodes (decimal IDs like 22.1) now preserved
- Can reconstruct CoNLL-U files exactly from Parquet
3. **Empty node detection fix**:
- conllu library represents 22.1 as tuple (22, '.', 1), not float
- Updated detection: isinstance(token['id'], tuple) and token['id'][1] == '.'
Verified: en_ewt captures 40 sentences with empty nodes correctly
Next: Regenerate all 235 treebanks with corrected format
