odin-foundation 1.2.2

Official Python implementation of ODIN (Open Data Interchange Notation)

odin-foundation

Official Python SDK for ODIN (Open Data Interchange Notation) — a canonical data model for transporting meaning between systems, standards, and AI.

Install

pip install odin-foundation

Requires Python 3.8+

Quick Start

import odin

doc = odin.parse("""
{policy}
number = "PAP-2024-001"
effective = 2024-06-01
premium = #$747.50
active = ?true
""")

print(doc["policy.number"])   # "PAP-2024-001"
print(doc["policy.premium"])  # 747.50

text = odin.dumps(doc)

Core API

Function	Description	Example
odin.parse(text)	Parse ODIN text into a document	doc = odin.parse(src)
odin.dumps(doc)	Serialize document to ODIN text	text = odin.dumps(doc)
odin.loads(text)	Alias for parse (Python-idiomatic)	doc = odin.loads(src)
odin.stringify(doc)	Alias for dumps	text = odin.stringify(doc)
odin.canonicalize(doc)	Deterministic bytes for hashing/signatures	b = odin.canonicalize(doc)
odin.validate(doc, schema)	Validate against an ODIN schema	result = odin.validate(doc, schema)
odin.parse_schema(text)	Parse a schema definition	schema = odin.parse_schema(src)
odin.diff(a, b)	Structured diff between two documents	changes = odin.diff(doc_a, doc_b)
odin.patch(doc, diff)	Apply a diff to a document	updated = odin.patch(doc, changes)
odin.parse_transform(text)	Parse a transform specification	tx = odin.parse_transform(src)
odin.execute_transform(tx, source)	Run a transform on data	out = odin.execute_transform(tx, doc)
doc.to_json()	Export to JSON	json_str = doc.to_json()
doc.to_xml()	Export to XML	xml_str = doc.to_xml()
doc.to_csv()	Export to CSV	csv_str = doc.to_csv()
odin.dumps(doc)	Export to ODIN	odin_str = odin.dumps(doc)
odin.builder()	Fluent document builder	odin.builder().section("policy")...

Schema Validation

import odin

schema = odin.parse_schema("""
{policy}
!number : string
!effective : date
!premium : currency
active : boolean
""")

doc = odin.parse(source)
result = odin.validate(doc, schema)

if not result.valid:
    for error in result.errors:
        print(error)

Transforms

import odin

transform = odin.parse_transform("""
map policy -> record
  policy.number -> record.id
  policy.premium -> record.amount
""")

result = odin.execute_transform(transform, doc)

Export

odin_str = odin.dumps(doc)    # ODIN string
json_str = doc.to_json()     # JSON string
xml_str  = doc.to_xml()      # XML string
csv_str  = doc.to_csv()      # CSV string

Builder

doc = (odin.builder()
    .section("policy")
    .set("number", "PAP-2024-001")
    .set("effective", date(2024, 6, 1))
    .set("premium", odin.currency(747.50))
    .set("active", True)
    .build())
