KgBase Markup Language

KgBase markup language is a user-friendly way to create graphs just by writing text.




name = "Tom Conway"
age = 23
:knows john

name = "john baez"
age = 54
:knows tom
:likes banana vinegar

The script above generates this graph in KgBase:

A KgBase script is just a list of nodes. Let's analyze the parts of a node:

1. Node Type

The type of this node is person. In the beginning example we have nodes of 2 types: person and food. In KgBase, nodes are grouped by their types in tables:

2. Node ID

The ID of this node is john. Its purpose is to identify the node so that you can create relationships linking to it in other nodes. Node Type and ID must be separated by a dot . and enclosed in square brackets []

3. Node Properties

This node has 2 properties: name and age. The value of each property comes after a = symbol. Properties can be of 2 types: number or string. Strings are enclosed in double quotes " ... ". Each new property will create a column in the corresponding table in KgBase.

4. Relationships

This nodes has 3 relationships with others nodes: It knows tom, it likes banana and it likes vinegar. Each of these relationships creates an edge in the KgBase graph. To create a relationship, you must start the line with : followed by the type of relationship (i.e. likes) and then a list on node ids, which refer to other nodes that you have created in the same script
