CORA
Real assets standards collaboration

Common Ontology for Real Assets

A vendor-neutral ontology for real estate and infrastructure data.Spanning the full capital stack, from operator to allocator and back.Being organized as a multi-stakeholder industry collaboration, global by design.To be openly licensed and publicly available.

Overview

What CORA Will Be

The real assets industry has accumulated multiple credible data standards over the past two decades. Each was developed for a defined audience and a defined use case. None was designed to provide the ontological layer that connects them, and none was designed for the workloads now arriving: agent-based reasoning systems that must interpret real assets data with semantic consistency across asset hierarchies, ownership structures, capital stacks, geographies, and time.

CORA is being organized to address that gap. The specification will define classes, relationships, identifiers, and provenance primitives for real estate (equity and debt) and infrastructure (data centers, renewables, transport). It will span the full capital stack from limited partners and general partners through asset managers, owner-operators, and service providers, and will be applicable globally. It will be vendor-neutral, openly licensed under Apache 2.0 and Creative Commons Attribution 4.0, and machine-readable in OWL, JSON-LD, and SHACL. It will sit above existing data exchange standards as the semantic layer that allows them to be interpreted consistently, rather than replacing them.

CORA Will Be

  • A common ontology for real estate and infrastructure data
  • A specification that spans the full capital stack, from LP to owner-operator
  • Globally applicable, with extension points for jurisdictional variation, and equally applicable within firms as between them
  • A vendor-neutral semantic layer above existing data exchange standards
  • A foundation for agent-readable real assets data
  • A multi-stakeholder collaboration governed in the open

CORA Will Not Be

  • A new data exchange format or transport protocol
  • A replacement for existing real estate data standards
  • A vendor product or a commercial deliverable
  • A mandate or a compliance requirement
  • A closed initiative, or one that requires membership fees
  • Specific to a single asset class, capital stack layer, or geography
v0.1 Scope

Scope of v0.1

Real assets data reconciliation breaks along three planes. v0.1 is designed to cover each.

v0.1 coverage matrixCORA v0.1 covers four capital stack layers (Limited Partner, General Partner, Asset Manager, Owner / Operator) across four asset class categories (Multifamily, Commercial, Debt, Infrastructure). All sixteen cells are within scope.DIFFERENT CONVENTIONS ACROSS COLUMNSMultifamilyCommercialDebtInfrastructureLimited PartnerGeneral PartnerAsset ManagerOwner / OperatorAGGREGATEDISAGGREGATEEACH CELL ALSO VARIES ACROSS GEOGRAPHIES
v0.1 covers the full capital stack across all four asset class categories. Data aggregates up the stack and disaggregates down; conventions differ across columns; each cell also varies across geographies.
Stack
Between operators, asset managers, general partners, and limited partners. Conventions differ at each layer, and each handoff requires interpretation.
Asset class
Across a diversified portfolio. Multifamily, office, industrial, retail, and other classes each carry distinct operational, valuation, and reporting conventions.
Geography
Across jurisdictions. Legal entity structures, lease conventions, valuation standards, regulatory regimes, and currencies differ by market.

The three planes compound. A global, diversified institutional investor lives at the intersection of all three. A vertically integrated real estate firm lives at the intersection internally, with the same friction occurring across business lines, acquired entities, and regional operations within a single organization. v0.1 is foundational and global from day one; sector-specific and jurisdiction-specific extensions follow in subsequent versions.

Asset classes

Real estate, equity

Multifamily, office, industrial and logistics, retail, hospitality, healthcare and senior housing, student housing, self-storage, and mixed-use. Direct property and portfolio structures, fund-level entities, ownership hierarchies, lease and operational data, valuation, transactions.

Real estate, debt

Mortgages, CMBS, mezzanine and preferred equity, construction lending, and other loan-level instruments. Servicer and lender entities. Securitization structures.

Infrastructure

Data centers, renewable energy assets, transport infrastructure, with defined extension points for additional sectors.

Capital stack

The ontology spans the full capital stack: limited partners and other capital allocators, general partners and fund sponsors, asset managers, owner-operators, property managers, fund administrators, and other service providers. CORA models the entities, relationships, and data flows that support consolidation from property-level operations up through portfolio, fund, and investor-level reporting, and the disaggregations required for analysis in the opposite direction.

Geographic scope

Global by design. The ontology accommodates jurisdictional variation in legal entity structures, lease conventions, valuation standards, regulatory regimes, and currency. Extension points support regional reporting requirements across North America, EMEA, APAC, and Latin America. Specific regulatory mappings, including those required for AIFMD, SEC, INREV, NCREIF, and equivalent regional regimes, are developed as part of the Standards Mapping working group.

Future versions extend coverage through community contribution and committee approval.

Status · in formation

Currently Underway

CORA is being organized as a multi-stakeholder standards initiative. The work in progress includes:

Founding partner discussions
Conversations with established real estate standards organizations, industry associations, and institutional stakeholders to confirm founding-period anchor signatories.
v0.1 specification drafting
Core ontology, relationship definitions, identifier patterns, and provenance primitives, with reference examples and validation tooling.
Working group structure and governance framework
Definition of the Specification Steering Committee, six initial working groups, public review and comment process, and long-term governance path.
Mappings to existing real estate data standards
Draft mappings between CORA and the principal industry data models, in coordination with the relevant standards organizations.
Specification Repository
The repository is public. The README, governance framework, and supporting documentation are available now. The v0.1 specification, mappings, and reference examples will be committed as they are approved.
Anticipated v0.1 Public Release
Q2 2026
The founding partner roster and the v0.1 specification will be announced together. The specification will then enter a public review and comment period.
Perspective

Why Now

At every layer of the real assets stack, data crosses systems that were not built to be interpreted together. The friction has always existed, but for two decades it was tolerable: the readers were human, and humans tolerate ambiguity. The next generation of consumers cannot absorb the semantic drift that human-mediated reporting absorbs by default.
