Data Standards

The Importance of Standardization​

Data standards are critical for the long-term viability, interoperability, and accessibility of sports competition data. The Competition Factory is built on the Tennis Open Data Standards (TODS), which provide a comprehensive, document-based representation of all tournament elements.

Why Data Standards Matter​

Long-Term Data Accessibility: Tournament data represents significant historical and statistical value. Without standards, organizations risk losing access to their own data when:

  • Software vendors go out of business
  • Maintenance contracts expire
  • Systems are upgraded with breaking changes
  • Database platforms become obsolete

Interoperability: Standardized data enables:

  • Integration between different tournament management systems
  • Data exchange with governing bodies and ranking systems
  • Aggregation of historical data across multiple platforms
  • Third-party analysis and visualization tools

Platform Independence: Standards-based data removes dependency on:

  • Specific database platforms (Oracle, SQL Server, MySQL, PostgreSQL)
  • Database versions and licensing models
  • Proprietary data formats
  • Vendor-specific APIs

Reproducibility: Standardized tournament records enable:

  • Complete reconstruction of tournament state at any point in time
  • Verification of seeding, draw generation, and progression logic
  • Audit trails for dispute resolution
  • Historical analysis and statistical research

Tennis Open Data Standards (TODS)​

The Competition Factory began as an implementation of the Tennis Open Data Standards (TODS), an ITF-led initiative to create a vendor-independent, JSON-based document format for tennis competition data. TODS provided the foundational data model — tournaments, events, draws, matchUps, participants, scoring, venues, and scheduling — and the factory fully supports TODS-compliant documents.

From TODS to CODES​

As the Competition Factory was deployed across more sports it was proven that the underlying data structures are not tennis-specific. The core concepts of participants, events, draws, matchUps, and scoring translate naturally across any sport that organizes bracket-based or round-robin competitions. The matchUpFormat code capabilities were extended to support the scoring needs of almost all imaginable sports.

To reflect this cross-sport reality, the data model used by the Competition Factory is now called CODES — Competition Open Data Exchange Standards.

CODES builds on TODS rather than replacing it. Any valid TODS document is a valid CODES document. CODES extends the model with:

  • Sport-agnostic terminology and conventions
  • Broader applicability beyond racquet sports
  • A governance model open to multiple sports federations

What CODES Provides​

CODES provides a JSON-based document format that captures:

Tournament Structure:

  • Tournament metadata (dates, location, categories)
  • Events (singles, doubles, team competitions)
  • Draw definitions and structures (elimination, round robin, compass)
  • Venues and courts with scheduling capabilities

Participants:

  • Individual persons with biographical and contact information
  • Pair participants (doubles teams)
  • Team participants with roster management
  • Representative organizations and officials

Competition Elements:

  • MatchUps with scheduling, scoring, and outcomes
  • Entry management and seeding protocols
  • Tie formats for team competitions
  • Participant lineups and substitutions

Temporal Data:

Audit and Metadata:

  • Position actions and draw modifications
  • Score history and point-by-point data
  • Officials assignments and notes
  • External references and media

Benefits Over Legacy Systems​

Traditional tournament management systems store data in relational database schemas that evolve over time, creating:

Schema Fragmentation: Each system version introduces schema changes, requiring:

  • Complex migration scripts
  • Business logic to handle multiple schema versions
  • Stored procedures specific to database platforms
  • Version-specific query patterns

Vendor Dependency: Database-centric architectures create reliance on:

  • Specific database platform licenses
  • Database administrator expertise
  • Backup and recovery procedures tied to database vendors
  • Export tools that may not preserve all relationships

Integration Challenges: Moving data between systems requires:

  • Schema mapping and transformation
  • Data type conversions
  • Relationship reconstruction
  • Manual validation and reconciliation

CODES Eliminates These Problems:

  • Single Document Format: All tournament data in one JSON file
  • Self-Describing: Schema embedded in document structure
  • Version Independent: Documents readable by any CODES-compliant processor
  • Database Agnostic: Store in filesystem, NoSQL, or relational databases
  • Human Readable: JSON format accessible to developers and analysts

Implementation in Competition Factory​

The Competition Factory provides:

Validation: Ensuring tournament records conform to CODES specifications Transformation: Converting legacy data to CODES format Generation: Creating valid CODES documents from scratch Querying: Extracting information from CODES documents efficiently Mutation: Modifying tournament state while maintaining CODES compliance

All factory operations preserve CODES compliance, ensuring that tournament records remain portable, accessible, and standards-compliant throughout their lifecycle.
