Open Agentic Schema Framework (OASF)

1 min read

Standardized schemas for defining AI agent capabilities and metadata.

Overview

How do you describe an agent's capabilities in a machine-readable way? OASF provides the answer with standardized schemas.

What OASF Defines

  • Agent Attributes: Unique identifiers, descriptions
  • Capabilities: What the agent can do
  • Relationships: How agents relate to each other
  • Metadata: Discovery and consumption information

Design Philosophy

OASF is inspired by OCSF (Open Cybersecurity Schema Framework), bringing similar rigor to agent definitions:

  • Attribute-based taxonomies
  • Extensible categories
  • Validation rules

Enterprise Applications

OASF enables:

  • Multi-dimensional discovery: Find agents by capability, domain, trust level
  • Interoperability: Consistent descriptions across frameworks
  • Verification: Schema validation for agent correctness

Integration Benefits

Studies suggest OASF reduces integration costs by 40-60% compared to custom implementations by standardizing:

  • Agent registration
  • Capability advertising
  • Discovery mechanisms

AGNTCY Initiative

AGNTCY is an open-source collective creating standards for agent interoperability:

  • OASF: Schema framework
  • Agent Directory: Discovery service
  • Agent Connect: Communication protocol
