Abstract
Contracts are the backbone of global commerce, yet the data within them remains trapped in proprietary formats. Every contract lifecycle management (CLM) platform, artificial intelligence extraction engine, and obligation tracking tool produces structured output, but each uses a custom schema, making data exchange costly, error-prone, and sometimes impossible. This paper presents Condicio, an open JSON Schema 2020-12 standard for representing structured contract intelligence data. We survey the landscape of existing legal data standards including LEDES, LegalXML, the Accord Project, SALI, OCDS, and others, and demonstrate that none address the specific problem of contract intelligence extraction output. We then present Condicio's architecture: a composable, confidence-aware schema covering parties, clauses, obligations, financial terms, risks, dates, definitions, and extraction metadata, all validated against a single JSON Schema 2020-12 document. We describe the design principles that guided the schema, which include extraction-first orientation, provenance tracking, language independence, and extensibility without fragmentation, and present examples across four contract types. Finally, we discuss governance models for the standard's evolution and the path toward industry adoption.
