Editing Meta Content Framework (section)

== MCF format ==
An MCF file consists of one or more blocks, each corresponding to an entity. A block looks like this:<syntaxhighlight lang="text" line="1">
Node: <identifier>
<property>: <value>, <value>
</syntaxhighlight>The identifier is a unique identifier for that entity (more on the scope of the identifier below) and is used to refer to that entity. The following lines each specify a property and one or more values, separated by commas. Each value can be a reference to another entity (via its identifier), a string (enclosed by double quotes) or a number. For example:<syntaxhighlight lang="text" line="1">
Node: Test1
typeOf: TestNode
child: Test2, Test3
name: "I am a test node"
itemCode: 42

Node: Test2
typeOf: TestNode
sibling: Test3
name: "I am another test node in a test world"

Node: Test3
typeOf: TestNode
sibling: Test2
name: "Just another test node in a test world"
</syntaxhighlight>NOTE: 

* The identifier must not include a comma (<code>,</code>) and must not be enclosed within double quotes.
* A common parsing failure is due to odd number of unescaped double quotes in text. For instance, <code>"foo bar" baz"</code> needs to be <code>"foo bar\" baz"</code>.
* Commas within double quotes are not considered as value separators.
* Every entity has at least one property: <code>typeOf</code>.
