Intblock discovery catalogues and roster sources

Catalogues Internacia searched when looking for missing international organizations and treaties, and the authorities used to compile membership. These lists are gap-finding tools. Internacia does not import them wholesale — a candidate still has to meet intblock-inclusion-policy.md. How to search catalogues and improve existing country / intblock records: discovery.md.

Per-record provenance and last_verified remain the field-level source of truth. This page records which catalogues were walked, when, and what was kept.

Discovery catalogues

Catalogue	URL	Retrieved	What was searched	What Internacia kept
UN Treaty Collection (UNTC)	treaties.un.org	2026-09-09	560+ multilateral instruments deposited with the UN Secretary-General	Named, in-force treaties with a durable states-parties roster distinct from an existing IGO. Constitutive acts of orgs already recorded (UN Charter, WHO Constitution, Rome Statute, IMO/ICC texts) are not duplicated. Not-in-force instruments and commodity-era pacts are skipped.
WTO RTA Information System	rtais.wto.org	2026-09-09	~388 RTAs in force (FTAs, customs unions, partial-scope PTAs, services EIAs)	Named plurilaterals, ASEAN+1, EU and US named FTAs, and bloc-to-bloc deals whose extra parties make a distinct roster. Untitled Country A – Country B pairs, UK continuity copies of EU EPAs, and services-only EIA rows of an FTA already recorded are not imported.
WTO Preferential Trade Arrangements Database	ptadb.wto.org	2026-09-09	37 notified non-reciprocal PTA rows (GSP, LDC-only DFQF, waiver programmes)	Named waiver programmes (AGOA, CBERA, CARIBCAN) and the EU GSP+ arrangement (GSPPLUS). National GSP ID cards, LDC-only DFQF schemes, and untitled one-country preferences are not imported.
UNCTAD IIA Navigator (by country grouping)	investmentpolicy.unctad.org	2026-09-09	33 country groupings; ~2,861 BITs and ~523 TIPs	Named plurilateral investment treaties with a ratifiers roster distinct from the parent IGO (OICIA, ACIA, UAIA, CISFTASERVICES, CJKIA, INTRAEUBIT, PCFI). SADC FIP and the ECOWAS Supplementary Act on Investments stay notes on the parent IGO. Bilateral BITs, FTA investment chapters of records already present, constitutive REC treaties, TIFAs, and not-in-force protocols are not imported.
Wikipedia .int organizations	List of organizations with .int domain names	2026-09-09	~231 named treaty/IGO-style entries with a .int site	Standing IGOs missing from intblocks, compiled from each org’s official site (ALLPI, ALSF, BOIP, CAC, CAFRAD, CEDARE, COMTELCA, CTU, EACO, EASF, ECB, ECSAHC, ECTEL, GCAP, GLFC, IAI, ICMP, ICPE, ICSTI, IICAS, IGC, INCAP, INL, ISTC, IVI, JINR, OSC, RECSA, RESPA, STCU, VPI, plus earlier ARC, Cospas-Sarsat, CRFM, EFI, GMCO, OIML, RIMES, UPOV). Dissolved or non-IGO .int holders are skipped.

Inclusion bars for RTAs, PTAs, and IIAs live in intblock-inclusion-policy.md.

Roster authorities

Discovery catalogues identify candidates. Membership (includes) is compiled from the official roster, not from the catalogue index card alone (WTO warns that accessions and withdrawals are under-notified).

Kind	Authority	Typical Internacia use
UN multilateral treaties	UNTC chapter status pages (treaties.un.org) and the treaty text	States-parties rosters, dates of consent, entry into force
Human-rights treaties	OHCHR instrument pages alongside UNTC	Core UN human-rights covenants and optional protocols
UNECE instruments	unece.org treaty and WP.29 pages	Environment protocols, inland transport, vehicle agreements
Commercial / trade law	UNCITRAL, WIPO Lex, OAS SICE	CISG family, paperless trade, IP and FTA texts
Crime / drugs / health	UNODC, WHO FCTC	UNTOC/UNCAC protocols, narcotics conventions, FCTC
WTO-notified FTAs	Official treaty text; RTA-IS as a cross-check	ASEAN+1, Agadir, CER, PICTA, EU and US named FTAs
EU trade agreements	European Commission, EUR-Lex	CETA, EU–Japan, EU–UK, EU–Korea, and related partnerships
US FTAs and PTAs	USTR and Federal Register	Remaining named U.S. FTAs; AGOA / CBERA beneficiary lists
Other PTA grantors	Government of Canada (CARIBCAN); EU GSP regulation (GSP+)	Waiver and GSP+ beneficiary rosters
Plurilateral IIAs	OIC COMCEC annex / UNCTAD IIA Navigator (ratifiers); ASEAN Secretariat (ACIA); League of Arab States / UNESCWA; CIS Executive Committee; Council of the EU treaty office; MOFCOM/MOFA treaty texts; Paraguay MFA (MERCOSUR protocols)	OIC Investment Agreement, ACIA, Unified Arab Capital Agreement, CIS services-and-investment FTA, CJK trilateral investment agreement, intra-EU BIT Termination Agreement, Intra-MERCOSUR PCFI
Standing IGOs (.int)	Each organization’s official membership page	ARC, Cospas-Sarsat, CRFM, EFI, GMCO, OIML, RIMES, UPOV, ALLPI, ALSF, BOIP, ECB, GCAP, IVI, JINR, and similar

Wikidata and English Wikipedia are used for entity linking (wikidata_id) and names, not as the membership source of truth when an official roster exists.

How to use a catalogue

Full search-and-improve loop (duplicate checks, hunt patterns, roster repair, country enrichment): discovery.md. Agent checklist: agents/discover.md.

1. Walk the catalogue for named, durable join targets (official acronym, distinct roster, in force or a historical predecessor already in the dataset).
2. Check Internacia for an existing id, alias, or parent IGO before adding a record. Constitutive instruments of an org already present stay off the intblock list.
3. Compile includes from the official roster or treaty status page. Stamp last_verified and at least four provenance entries (catalogue + roster authority).
4. Follow intblock-inclusion-policy.md for id, directory/blocktype, and scope_category.

Worked add walkthrough: agents/add-intblock-example.md.
