The Chart Object Specification™ (COS) Version 1.0

Document Classification

This publication introduces the Chart Object Specification™ (COS), a proposed canonical representation for persistent analytical visualizations.

The objective of COS is to define a machine-readable object model capable of representing charts independently of any rendering engine, application, or storage technology.

This publication defines the conceptual specification only.

Implementation status is identified throughout.

Specification Status

Production — Implemented within the current Chartix platform.

Active Development — Implementation in progress. Object definitions may evolve before stabilization.

Research Direction — Proposed extensions intended for future versions of the specification. These sections are architectural proposals rather than implemented functionality.

Abstract

Most charts exist only as renderings.

• PNG.
• SVG.
• PDF.
• PowerPoint.
• Canvas.

None of these formats fully describe the analytical object that produced the visualization.

Chartix proposes the Chart Object Specification.

Rather than storing charts as graphics, COS stores charts as structured computational objects.

The rendered visualization becomes one possible output.

The Chart Object becomes the permanent source of truth.

Design Goals

COS is designed around ten objectives.

• Platform independent.
• Rendering independent.
• Data source independent.
• Machine readable.
• Version aware.
• Governance aware.
• Identity preserving.
• Synchronization ready.
• API friendly.
• Future extensible.

The Chart Object

Every Chart Object possesses a globally unique identifier.

Example:

chart://finance/revenue/monthly-growth

Identity is permanent.

Rendering is temporary.

Canonical Object Structure

Every Chart Object contains the following sections.

Each layer remains logically independent.

Object Definition

Conceptual representation:

{
  "id": "chart://finance/revenue/monthly-growth",
  "version": 18,
  "semantic": {},
  "visual": {},
  "connector": {},
  "synchronization": {},
  "governance": {},
  "relationships": {},
  "metadata": {}
}

This document intentionally omits implementation-specific fields. Individual implementations may extend the specification while preserving compatibility.

Identity Layer

Every object contains:

• Persistent Identifier
• Creation Timestamp
• Current Version
• Object Type
• Namespace
• Owner
• Organization

Identity never changes.

Only versions evolve.

Semantic Layer

The Semantic Layer describes business meaning.

Examples include:

• Metrics
• Dimensions
• Aggregations
• Units
• Business Definitions
• Time Grain
• Relationships
• Calculated Fields

The Semantic Layer is independent of presentation.

Visual Layer

The Visual Layer defines rendering.

Examples include:

• Chart Type
• Axis Configuration
• Labels
• Colors
• Fonts
• Spacing
• Themes
• Accessibility Rules

Changing appearance does not modify semantic identity.

Connector Layer

The Connector Layer describes data origin.

Potential connector types include:

• Spreadsheet
• Database
• Warehouse
• API
• CSV
• Streaming Source
• Manual Dataset

Connectors are interchangeable.

Synchronization Layer

The Synchronization Layer maintains operational state.

Possible attributes include:

• Synchronization Policy
• Last Refresh
• Refresh Interval
• Validation Status
• Connector Health
• Publication Status

Future implementations may expose additional operational metadata.

Governance Layer

Governance defines organizational control.

Potential properties include:

• Owner
• Approver
• Permissions
• Retention Policy
• Lifecycle State
• Compliance Tags
• Audit References

Governance remains independent of rendering.

Version Layer

Every Chart Object possesses immutable revisions.

Each revision records:

• Version Number
• Timestamp
• Author
• Reason
• Connector Version
• Approval Status

Historical versions remain accessible.

Publishing Layer

Charts may publish to multiple destinations.

Examples include:

• Website
• PowerPoint
• Google Slides
• PDF
• Notion
• Confluence
• API
• Dashboard

Publishing references the Chart Object.

Destinations do not become independent charts.

Relationship Layer

Relationships connect Chart Objects to other entities.

Examples include:

• Depends On
• Uses Dataset
• Uses Metric
• Published In
• Owned By
• Derived From
• Supersedes
• Referenced By

Relationships support organizational intelligence.

Metadata Layer

Metadata provides implementation-specific context.

Examples include:

• Tags
• Descriptions
• Keywords
• Classification
• Industry
• Department
• Business Unit
• Custom Fields

The Metadata Layer remains extensible.

Production Capability

Structured Chart Representation™

Status: Production. Chartix currently represents recovered charts as editable structured objects rather than fixed images. This provides the initial foundation for future COS implementations.

Active Development

Persistent Chart Identity™

Status: Active Development. Every Living Chart is being assigned a permanent identity independent of export format.

Versioned Chart Objects™

Status: Active Development. Chart Objects are evolving toward immutable revision history.

Connector Abstraction™

Status: Active Development. Data connectors are being standardized through common interfaces independent of storage technology.

Research Direction

Open Chart Object Specification™

Chartix is exploring a future vendor-neutral specification allowing third-party software to exchange Living Chart Objects while preserving identity and semantics. This direction is exploratory and no public standard currently exists.

Portable Chart Objects™

Future implementations may allow a complete Chart Object to move between compatible systems without losing:

• Identity
• History
• Governance
• Relationships
• Synchronization
• Semantic meaning

Distributed Chart Objects™

Future enterprise deployments may support distributed synchronization across multiple organizations while maintaining object identity.

Cryptographic Provenance™

Future versions may attach cryptographic signatures to Chart Objects.

Potential applications include:

• Integrity verification
• Authenticity
• Publication verification
• Regulatory reporting
• Scientific publishing

Interoperability Layer™

Future COS implementations may support translation between Chart Objects and external visualization formats where practical. The objective is interoperability without compromising semantic identity.

Engineering Principles

The Chart Object Specification follows twelve principles.

1. Charts are objects.
2. Objects possess permanent identity.
3. Meaning is independent of rendering.
4. Rendering is replaceable.
5. Versions are immutable.
6. Governance is native.
7. Relationships are explicit.
8. Synchronization is operational.
9. Metadata is extensible.
10. Connectors are modular.
11. Specifications remain portable.
12. Future extensions preserve compatibility.

Future Vision

Chartix proposes a future in which charts become first-class computational resources.

Just as software engineering standardized around source files, commits, repositories, and APIs, analytical infrastructure may benefit from standardized chart objects capable of moving across systems while preserving identity and meaning.

The Chart Object Specification represents one possible foundation for that future.

Conclusion

Charts have historically been treated as files.

The Chart Object Specification proposes treating charts as persistent computational objects.

Identity. Semantics. Governance. Relationships. Synchronization. Version history. Publishing.

These become intrinsic characteristics of every chart rather than external workflows.

Chartix believes this model provides a foundation for the next generation of analytical infrastructure.
