# Quick reference for common tasks

# Data Operations
oxirs init mydata                              # Create new dataset
oxirs import mydata file.ttl -f turtle         # Import data

Performance Tips

For Large Datasets (>1M triples):

Use batch import with parallel processing: oxirs batch import --dataset mydata --files *.nt --parallel 8
Use TDB loader for bulk loading: oxirs tdbloader mydata *.nt --progress --stats
Stream large exports: oxirs export mydata output.nq --format nquads | gzip > output.nq.gz

For Query Performance:

Analyze queries before execution: oxirs explain mydata query.sparql --file --mode full
Use appropriate output format (JSON for programmatic use, table for humans)
Enable query caching for repeated queries

Troubleshooting

Issue	Solution
"Dataset not found"	Run `oxirs init <name>` first to create the dataset
"Format not recognized"	Specify format explicitly with `--format` flag
"Permission denied"	Check directory permissions with `chmod 755 <dir>`
"Port already in use"	Use different port with `--port <num>`
"Out of memory"	Use streaming operations or increase batch size
"Invalid SPARQL syntax"	Use `oxirs qparse` to validate query syntax

Debug Mode:

# Enable verbose logging
oxirs --verbose query mydata "SELECT * WHERE {?s ?p ?o}"

# Debug specific modules
RUST_LOG=oxirs_core=debug,oxirs_arq=trace oxirs query mydata query.sparql
