+= DataSonnet Language
+:docTitle: DataSonnet
+:artifactId: camel-datasonnet
+:description: To use DataSonnet scripts in Camel expressions or predicates.
+:since: 3.7
+:supportLevel: Preview
+include::{cq-version}@camel-quarkus:ROOT:partial$reference/languages/datasonnet.adoc[opts=optional]
+
+*Since Camel {since}*
+
+Camel supports https://datasonnet.com/[DataSonnet] transformations to allow an
Expression or Predicate to be used in the Java DSL or
xref:manual::xml-configuration.adoc[XML
+Configuration].
+
+To use a DataSonnet expression use the following Java code:
+[source,java]
+---------------------------------------
+... datasonnet("someDSExpression") ...
+---------------------------------------
+
+== Example
+
+Here is a simple example using a DataSonnet expression as a predicate in a
Message Filter:
+
+[source,java]
+------------------------------------------------------------------------------------------------
+// lets route if a line item is over $100
+from("queue:foo")
+ .filter(datasonnet("ds.arrays.firstWith(body.lineItems, function(item)
item > 100) != null"))
+ .to("queue:bar")
+------------------------------------------------------------------------------------------------
+
+And the XML DSL:
+
+[source,xml]
+-----------------------------------------------------------------------------
+<route>
+ <from uri="queue:foo"/>
+ <filter>
+ <datasonnet>ds.arrays.firstWith(body.lineItems, function(item) item >
100) != null</datasonnet>
+ <to uri="queue:bar"/>
+ </filter>
+</route>
+-----------------------------------------------------------------------------
+
+Here is an example of a simple DataSonnet expression as a transformation EIP.
This example will transform an XML body with
+`lineItems` into JSON while filtering out lines that are under 100.
+
+[source,java]
+------------------------------------------------------------------------------------------------
+from("queue:foo")
+ .transform(datasonnet("ds.filter(body.lineItems, function(item) item >
100)", String.class)
+ .bodyMediaType("application/xml").outputMediaType("application/json")
+ )
+ .to("queue:bar")
+------------------------------------------------------------------------------------------------
+
+And the XML DSL:
+
+[source,xml]
+-----------------------------------------------------------------------------
+<route>
+ <from uri="queue:foo"/>
+ <filter>
+ <datasonnet bodyMediaType="application/xml"
outputMediaType="application/json" resultTypeName="java.lang.String" >
+ ds.filter(body.lineItems, function(item) item > 100)
+ </datasonnet>
+ <to uri="queue:bar"/>
+ </filter>
+</route>
+-----------------------------------------------------------------------------
+
+== Setting result type
+
+The xref:datasonnet-language.adoc[DataSonnet] expression will return a
`com.datasonnet.document.Document` by default. The
+document preserves the content type metadata along with the contents of the
result of the transformation. In predicates,
+however, the Document will be automatically unwrapped and the boolean content
will be returned. Similarly any times you
+want the content in a specific result type like a String. To do this you have
to instruct the
+xref:datasonnet-language.adoc[DataSonnet] which result type to return.
+
+In Java DSL:
+
+[source,java]
+----
+datasonnet("body.foo", String.class)
+----
+
+In XML DSL you use the *resultType* attribute to provide a fully
+qualified classname:
+
+[source,xml]
+----
+<datasonnet resultType="java.lang.String">body.foo</datasonnet>
+----
+
+If the expression results in an array, or an object, you can instruct the
expression to return you `List.class`
+or `Map.class`, respectively. However, you must also set the output media type
to `application/x-java-object`.
+
+NOTE: The default `Document` object is useful in situations where there are
intermediate transformation steps, and so
+retaining the content metadata through a route execution is valuable.
+
+== Specifying Media Types
+
+Traditionally the input and output media types are specified through the
+https://datasonnet.s3-us-west-2.amazonaws.com/docs-ci/primary/master/datasonnet/1.0-SNAPSHOT/headers.html[DataSonnet
Header]
+The xref:datasonnet-language.adoc[DataSonnet] expression provides convenience
options for specifying the body and output
+media types without the need for a Header, this is useful if the
transformation is a one-liner, for example.
+
+The DataSonnet expression will look for a body media type in the following
order:
+
+1. If the body is a `Document` it will use the metadata in the object
+2. If the convenience bodyMediaType method was used, it will use its value
+3. A "CamelDatasonnetBodyMediaType" exchange property
+4. A "Content-Type" message header
+5. The DataSonnet Header payload media type directive
+6. `application/x-java-object`
+
+And for output media type:
+
+1. If the convenience outputMediaType method was used, it will use its value
+2. A "CamelDatasonnetOutputMediaType" exchange property
+3. A "CamelDatasonnetOutputMediaType" message header
+4. The DataSonnet Header output media type directive
+5. `application/x-java-object`
+
+== Functions
+
+Camel adds the following DataSonnet functions that can be used to access the
+exchange:
+
+[width="100%",cols="10%,10%,10%,70%",options="header",]
+|===
+|Function |Argument |Type |Description
+
+|cml.properties |key for property |String |To lookup a property using the
+xref:ROOT:properties-component.adoc[Properties] component (property
placeholders).
+
+|cml.header |the header name |String |Will return the message header.
+
+|cml.exchangeProperty |key for property |String |Will return the exchange
property.
+|===
+
+Here's an example showing some of these functions in use:
+
+[source,java]
+------------------------------------------------------------------------------------------------
+from("direct:in")
+ .setBody(datasonnet("'hello, ' + cml.properties('toGreet')", String.class))
+ .to("mock:camel");
+------------------------------------------------------------------------------------------------
+
+And the XML DSL:
+
+[source,xml]
+-----------------------------------------------------------------------------
+<route>
+ <from uri="direct:in"/>
+ <setBody>
+ <datasonnet resultTypeName="java.lang.String">'hello, ' +
cml.properties('toGreet')</datasonnet>
+ </setBody>
+ <to uri="mock:camel"/>
+</route>
+-----------------------------------------------------------------------------
+
+== Loading script from external resource
+
+You can externalize the script and have Camel load it from a resource
+such as `"classpath:"`, `"file:"`, or `"http:"`. +
+This is done using the following syntax: `"resource:scheme:location"`,
+eg to refer to a file on the classpath you can do:
+
+[source,java]
+-------------------------------------------------------------------
+.setHeader("myHeader").datasonnet("resource:classpath:mydatasonnet.ds")
+-------------------------------------------------------------------
+
+== Dependencies
+
+To use scripting languages in your camel routes you need to add a
+dependency on *camel-datasonnet*.
+
+If you use Maven you could just add the following to your `pom.xml`,
+substituting the version number for the latest and greatest release (see
+the download page for the latest versions).
