We need to be able to

describe and connect 

the components.

Data. Software. Hardware. People.

Metadata

Mechanisms for modeling relationships between the information gathered from contextual sources.

Schema

Conceptual framework where

semantic metadata can be recorded.

We need to "crosswalk" different signifiers and meanings.

We need to create a schema that is implementation agnostic.

Machine-actionable

• Supports:
  • Search Engine Optimization (SEO)
  • Federated search via APIs
• Describe one mission or many.

Early adopters: SatNOGS

first implementation / example

No single example can represent all needs

SatNOGS is set to implement the first version of MetaSat this spring.

MetaSat currently represents this group's needs  best.

We hope you'll help us tackle areas that are more relevant to you
