justicedao/ipfs_greece_laws_ir

Greece legislation IR (CID-keyed sparse GraphRAG)

Research retrieval release of endomorphosis/ipfs_greece_laws (revision a3df2d112411047517ff30da931a8e427c09d071) packaged as country-laws-ir-graphrag/v1 (layout family skillcenter-huggingface-release/v3 / publicus-ir).

Not legal advice. This is a research snapshot. The official gazette / authentic source of Greece prevails over this corpus. Retrieved documents and graph edges are retrieval evidence only. No legal text was invented.

Primary key: entry_cid (CIDv1 raw sha2-256 of a canonical identity record). Integer document_index values are compact shard pointers, not identities.

Target Hub id (packaging metadata only): justicedao/ipfs_greece_laws_ir.

Canonical fields

entry_cid, law_cid, record_type, jurisdiction, language, instrument_id, instrument_title, article_number, article_title, title, body, source_url, snapshot_date, coverage, license, collector, source_dataset, source_revision.

Unit policy: prefer article/section rows; fall back to law-level when articles.parquet is empty.

Index layout

Zstandard parquet shards with at most 4,096 rows.

• indexes/bm25_keyword_shards.parquet — lexical term ranges → BM25 posting shards
• indexes/vector_chunks.parquet — semantic routing centroids (rows sorted by cosine to shard centroid)
• indexes/corpus_chunks.parquet — document ranges → corpus shards
• data/graph/nodes / data/graph/edges — property graph
• data/graph/adjacency/{incoming,outgoing} — score-ordered neighbor pages

BM25: Okapi k1=1.2, b=0.75, title_weight=5, body_weight=1 (FTS5 unicode61-style tokenizer).

Graph: one node per entry_cid plus facet nodes (_facet_cid(kind, value) for jurisdiction, language, instrument, source, status). Neighbor edges BM25_NEIGHBOR_OF (k=8) carry score and matched terms. Structural edges: ARTICLE_OF (article → parent law) when articles exist, plus IDENTIFIED_BY_ELI / IDENTIFIED_BY only when those identifiers are present in the source.
