gedcom-x 0.5.14

Python implimentation of gedcom-x standard

GEDCOM-X Python Toolkit (gedcom-x alpha 0.5.13)

class-based Python implementation of the GEDCOM-X data model.

⚠️ Project Goals

This project is currently in alpha.
While the core GEDCOM-X classes and serialization are functional, some features may not be fully implemented or may not behave exactly as expected.

Features

Feature	Implimentation Level	Description
Class Based Gedcom-X	Mostly Implimented	Some types need to be completed (ex. 'Group')
Gedcom-X Extensibility	Mostly Implimented	uses decorators and schema to register custom types/fields
Gedcom-X Serialization	Mostly Implimented	JSON Only, edge case handling needs work
Gedcom-X -> GEDCOM 5	Not Implimented
Gedcom 5 Read\Parse	Mostly Implimented	edge TAG abd extensions not fully implimented
Gedcom 5 Editing	Partialy Implimented	Editing at tag (element) level, with helper functions
Gedcom 5 Writing	Fully Implimented
GEDCOM 5 -> Gedcom-X	Mostly Implimented	edge TAG abd extensions not fully implimented
Gedcom-X -> GEDCOM 7	Not Implimented
Gedcom 7 Read\Parse	Mostly Implimented	edge TAG abd extensions not fully implimented
Gedcom 7 Editing	Partialy Implimented	Editing at tag (element) level, with helper functions
Gedcom 7 Writing	Not Implimented	Needs to be built using gx7 schema checks

• Certain GEDCOM 5/7 tags are not yet mapped (MAP, _DATE, _TEXT, _PHOTO, FSID, SSN) inlcuding most extended _TAGS
• Some classes may be missing methods or fields
• Error handling and validation are still evolving
• Backward compatibility is not guaranteed until the first stable release

✅ What You Can Do

• Create and manipulate GEDCOM-X objects in Python
• Serialize and deserialize data to/from JSON
• Experimentally convert GEDCOM 5x & 7 files into GEDCOM-X JSON
• Extend GedcomX to handle new types or custom attributes

❌ What You Can’t Do (Yet)

• Rely on complete coverage of all GEDCOM 5/7 tags
• Expect perfect compliance with the GEDCOM-X specification
• Serialize and deserialize data to/from XML
• Assume strong validation or error recovery on malformed input
• Use it as a drop-in replacement for production genealogy software
• Write GEDCOM-X to GEDCOM 5x / 7
• Create Graphs from Genealogies

Contributors and testers are welcome — feedback will help stabilize the library!

---

This library aims to provide:

• Python classes for every GEDCOM-X type (Person, Fact, Source, etc.)
• Extensibility, with current GEDCOM RS etc, extension built in
• Serialization and Deserialization to/from GEDCOM-X JSON
• Utilities to convert GEDCOM 5x & 7 GEDCOM Files into GEDCOM-X and back
• Type-safe field definitions and extensibility hooks for future tags

---

Features

• Complete GEDCOM-X Class Coverage
  Each GEDCOM-X type is represented as a Python class with fields and types.

• Serialization / Deserialization
  Centralized serialization/deserialization using schema that can register extended types and properties

• Type Checking & Enum Validation
  Uses Python type hints and enums to ensure correct values (e.g. FactType, EventType, ConfidenceLevel).

• Composable / Nestable Classes
  Nested objects (e.g. Person → Name → NameForm → TextValue) are constructed and validated recursively.

• GEDCOM 7 → GEDCOM-X Conversion
  Experimental parser to read GEDCOM 7 files and convert them into structured GEDCOM-X JSON.

Examples

Create a Person Gedcom-X Type

import json
from gedcomx import Person, Name, NameForm, TextValue

person = Person(
    id="P-123",
    names=[Name(
        nameForms=[NameForm(
            fullText=TextValue(value="John Doe")
        )]
    )]
)

print(json.dumps(person._as_dict_,indent=4))

{
    "id": "P-123",
    "lang": "en",
    "private": false,
    "living": false,
    "gender": {
        "lang": "en",
        "type": "http://gedcomx.org/Unknown"
    },
    "names": [
        {
            "lang": "en",
            "nameForms": [
                {
                    "lang": "en",
                    "fullText": {
                        "lang": "en",
                        "value": "John Doe"
                    }
                }
            ]
        }
    ]
