ASDF Specification Resources

The included schema and manifest resources made available by the ASDF are described below.

ASDF Specification Schema Definitions

ASDF schemas are arranged into “modules”. All ASDF implementations must support the “core” module, but the other modules are optional.

• Core
  • core/asdf-1.1.0
  • core/complex-1.0.0
  • core/datatype-1.0.0
  • core/extension_metadata-1.0.0
  • core/ndarray-1.1.0
  • core/constant-1.0.0
  • core/software-1.0.0
  • core/history_entry-1.0.0
  • core/integer-1.1.0
  • core/externalarray-1.0.0
• Astronomy
  • fits/fits-1.1.0
  • table/column-1.1.0
  • table/table-1.1.0
  • time/time-1.2.0
  • unit/unit-1.0.0
  • unit/defunit-1.0.0
  • unit/quantity-1.2.0
• Legacy schemas
  • core/asdf-1.0.0
  • core/column-1.0.0
  • core/integer-1.0.0
  • core/ndarray-1.0.0
  • core/subclass_metadata-1.0.0
  • core/table-1.0.0
  • fits/fits-1.0.0
  • time/time-1.0.0
  • time/time-1.1.0
  • unit/quantity-1.1.0
  • asdf-schema-1.1.0
  • transform/transform-1.0.0
  • transform/domain-1.0.0

The ASDF Specification also defines a meta-schema that is useful for validating the ASDF schemas themselves. These schemas are useful references when creating custom schemas (see Designing a new tag and schema).

• YAML Schema

ASDF Core Schema Manifests

The ASDF tags (described by schemas) available under each ASDF core schemas version are all described by a single manifest document for that ASDF specification version.

• core-1.0.0
• core-1.1.0
• core-1.2.0
• core-1.3.0
• core-1.4.0
• core-1.5.0
• core-1.6.0

The non-core (astronomy) tags are described separately:

• astronomy-1.0.0
