-=Binding=\r
-Binding is a mechanism for mapping a Java Class to a Datatype.\r
-For example, take a java.lang.Double. The instance is a container (<code>private final double value;</code>) for the data and its Binding (DoubleBinding) is a way to access the data (<code>.valueOf()</code>, <code>.getDouble()</code>). \r
- Java Object + Binding = Databoard Value\r
-\r
-Bindings have the exact same composition tree structure as its respective <code>Datatype</code> - structural types have structural Bindings, and primitive types a single binding. To acquire a binding, the developer can use a utility that creates one using Java reflection functions.\r
-<pre class="code">\r
- Binding binding = Binding.getBinding( Double.class );\r
-</pre>\r
-\r
-Sometimes classes cannot bound using automatic tool, for instance when using 3rd party classes which cannot be modified. The developer must then write binding self by sub-classing on of the 13 base binding classes (There is a base binding class for each Datatype). \r
-<pre class="code">\r
- Binding binding = new RecordBinding() { ... };\r

-===Serialization===\r
-[../javadoc/org/simantics/databoard/serialization/binary/Serializer.html|Serializer] is a class that serializes Values into and from binary serialization format. It follows the Databoard [Databoard_Specification#Binary_File_Format|Binary File Format].\r

-</pre>\r
-\r
-Files can be partially accessed using BinaryAccessor, see [accessor|Accessors]. This is useful when handling larger than memory files.\r
-\r
-===Validation===\r
-'''Value''' can be ''well-formed'' or ''valid''. \r
-The domain of valid values are defined with restrictions in data types, and <code>@Length</code>, <code>@Range</code>, <code>@Pattern</code> and <code>@MIMEType</code> Annotations in Classes\r
-\r
-Validation mechanism in Binding asserts that the instance is a valid value of the respective Data Type.\r
-<pre class="code">\r

- } catch( BindingException e ) {\r
- // In-valid object\r

-===Other Notes===\r
-*<tt>Binding</tt> is a <tt>Comparator</tt>, all data values are comparable, the order is defined in [[Databoard_Specification#Comparison|Specification]].\r
-*<tt>Binding#createDefault()</tt> creates a valid instance of the Datatype.\r
-*<tt>Binding#createRandom(int)</tt> creates a valid instance with random values. Useful for unit tests.\r
-*<tt>Binding#clone(Object)</tt> creates a new instance with same content.\r
-*<tt>Binding#readFrom(Object, Binding, Binding)</tt> copies contents from another object of same type.\r
-\r
-===Parsing & Printing===\r
-\r
-Data values are printed and parsed of the [[Databoard_Specification|Text notation]] with the following <code>Binding</code> methods:\r
-<pre class="code">\r
- String text = binding.printValue( value, true );\r
- \r
- Object value = binding.parseValue( text );\r

+== Mapping Scheme ==
+A ''binding scheme'' associates some data types with a unique binding. The mapping of types to bindings is bijective, there is one binding for each type and vice-versa.
+
+<code>DefaultBindingScheme</code> is a scheme that converts any datatype to a binding. It prefers java.lang.X primitives.
+The Class mapping for each type is listed below.
+{| style="background-color: #f9f9f9; border: 1px solid #aaaaaa; "
+|- style="background-color: #e9e9e9;
+| '''Type''' || '''Class'''
+|-
+| <code>BooleanType</code> || <code>Boolean.class</code>
+|-
+| <code>ByteType</code> || <code>Byte.class</code>
+|-
+| <code>FloatType</code> || <code>Float.class</code>
+|-
+| <code>DoubleType</code> || <code>eDouble.class</code>
+|-
+| <code>IntegerType</code> || <code>Integer.class</code>
+|-
+| <code>LongType</code> || <code>Long.class</code>
+|-
+| <code>StringType</code> || <code>String.class</code>
+|-
+| <code>UnionType</code> || <code>TaggedObject.class</code>
+|-
+| <code>OptionType</code> || <code>ValueContainer.class</code>
+|-
+| <code>RecordType</code> || <code>Object[].class</code>
+|-
+| <code>ArrayType</code> || <code>ArrayList.class</code>
+|-
+| <code>Array(Byte)</code> || <code>byte[].class</code>
+|-
+| <code>MapType</code> || <code>TreeMap.class</code>
+|-
+| <code>VariantType</code> || <code>Variant.class</code>
+|}
+
+<code>MutableBindingScheme</code> is a scheme that provides a fully implementing mutable binding for all data types.
+The Class mapping for each type is listed below.
+
+{| style="background-color: #f9f9f9; border: 1px solid #aaaaaa; "
+|- style="background-color: #e9e9e9; " |

+===Serialization===
+[../javadoc/org/simantics/databoard/serialization/binary/Serializer.html|Serializer] is a class that serializes Values into and from binary serialization format. It follows the Databoard [Databoard_Specification#Binary_File_Format|Binary File Format].
+<pre class="code">
+ Binding binding = Bindings.DOUBLE;
+ Serializer serializer = Bindings.getSerializer( binding );
+ byte[] data = serializer.serialize( new Double( 100.0 ) );
+
+ Double value = (Double) serializer.deserialize( data );
+</pre>
+
+Files can be partially accessed using BinaryAccessor, see [accessor|Accessors]. This is useful when handling larger than memory files.
+
+===Validation===
+'''Value''' can be ''well-formed'' or ''valid''.
+The domain of valid values are defined with restrictions in data types, and <code>@Length</code>, <code>@Range</code>, <code>@Pattern</code> and <code>@MIMEType</code> Annotations in Classes
+
+Validation mechanism in Binding asserts that the instance is a valid value of the respective Data Type.
+<pre class="code">
+ try {
+ Binding.assertInstaceIsValid( object );
+ } catch( BindingException e ) {
+ // In-valid object
+ }
+</pre>
+
+===Other Notes===
+*<tt>Binding</tt> is a <tt>Comparator</tt>, all data values are comparable, the order is defined in [[Databoard_Specification#Comparison|Specification]].
+*<tt>Binding#createDefault()</tt> creates a valid instance of the Datatype.
+*<tt>Binding#createRandom(int)</tt> creates a valid instance with random values. Useful for unit tests.
+*<tt>Binding#clone(Object)</tt> creates a new instance with same content.
+*<tt>Binding#readFrom(Object, Binding, Binding)</tt> copies contents from another object of same type.
+
+===Parsing & Printing===
+
+Data values are printed and parsed of the [[Databoard_Specification|Text notation]] with the following <code>Binding</code> methods:
+<pre class="code">
+ String text = binding.printValue( value, true );
+
+ Object value = binding.parseValue( text );
+</pre>
+And also to value definitions <tt>''name : type = value''</tt>
+
+<pre class="code">
+ StringBuilder sb = new StringBuilder();
+ DataValueRepository repo = new DataValueRepository();
+ repo.put( "temp", binding, value );
+ binding.printValue( value, sb, repo, true );
+ String text = sb.toString();
+
+ Object value = binding.parseValueDefinition( text );
