Properties

A property if a piece of information describing a characteristic of an entity.

A property consists essentially of two elements: its name, identified by a TAG, and its VALUE.

 

Description

Let's consider the following three properties.

These three properties share the same name (City), but have different values: London, Paris and Rome.

The City is coded in the Gedcom file by the tag CITY, in capital letters.

 

Tags

The Gedcom standard defines a large number of genealogical properties.

Each of these properties is identified by a Tag, which make each of them unique and unambiguous.

Here are some examples of properties and their tags between parenthesis.

For more details:

 

Usage

In the Gedcom file, properties always keep the same structure and follow strictly the same syntax rules.

In Ancestris, properties exactly correspond to the Gedcom properties, but they may look different depending on the view that displays them.

Properties in the Gedcom file

Each line of the Gedcom file is a property.

Each property line has the following format:

Number is the hierarchical level of the property as described in the Gedcom page.

Example:

2 DATE 27 SEP 1601

The first item is the number 2, indicating the level of the row in the record entity.

The second element is the DATE tag, indicating that the property is a date.

The third element is the value of the date (27 SEP 1601).

Therefore, the whole line means that the date of the genealogical element above this line, is September 27, 1601.

Properties in the Gedcom editor

The Gedcom editor displays property lines in a manner quite similar to that of the Gedcom file: one line per property, containing the tag followed by its value.

However, the following differences exist.

Properties in the other editors

In editors, properties are displayed in the user's language.

In the Aries and Cygnus editors, neither the labels, nor the lines, nor their tree structure appear: the name of each field, more explicit than a simple tag, simply invites the user to fill it in, as we fill in a form.

Properties in the Entities Table

In the Entity Table, each row represents an entity, and each column represents a property.

It is possible to configure the Table in order to choose the properties to display.

Properties displayed in windows

Other windows display properties, and allow them to be viewed, printed or edited (Navigator, Dynamic tree, etc.).
