Data-Construction Roadmap
HDARP extraction turned the source PDFs into a validated knowledge base of text and tables. The next phase applies the Anu data-construction framework to turn that knowledge base into harmonized, analyzable time-series panels — a single source of truth with full provenance per series.
Status: scoped (not yet built). 108 panel-capable series and 158 single-doc cross-sectional sources have been identified in the scoping pass (the Explorer surfaces the conservative tally of 98 panel-capable clusters). The flagship clusters below are prioritized by analytical value × readiness. No panels are constructed yet — the figures here describe the planned scope, drawn from the project's scope document.
Flagship clusters
Imperial → Soviet Fiscal Panel (PILOT)
Annual state revenue-by-source + expenditure-by-ministry across two regimes; deep-validated 1856–1887 core.
Foreign Trade Panel
Imports/exports by country & commodity; ~12k tables, biggest single Soviet panel.
National-Economy Yearbooks (narodnoe khozyaystvo)
Core macro indicators by union republic-year; a Soviet regional panel.
Military Ministry Reports
Annual war-ministry reports; 8,633 tables — largest imperial table trove.
Sector Panels (prison / agriculture / industry / census / transport)
Penal statistics, agriculture, industry, the 1897 census + revisions, MPS railway/transport bulletins.
Harmonization challenges (designed once, reused)
- Currency: silver- / credit- / gold-ruble (1897 reform) / Soviet ruble (1922 · 1947 · 1961 redenominations) — a deflator/units column, not naive concatenation.
- Calendar: Julian → Gregorian (Feb 1918) for sub-annual alignment.
- Administrative units: governorates (guberniya) → oblasts/krais → union republics crosswalk.
- Category drift: ministries & revenue articles rename/split across years.
- Orthography: pre-1918 Russian letters (ъ ѣ і ѳ) normalized for joins, originals preserved.
- Regime break (1917): Imperial and Soviet kept linked-but-flagged, not merged.
