Usage

Parser

var statement = xdi.parser.parseStatement('=markus<#email>&/&/"Markus"');
for (var i in statement.subject().subsegments()) alert(statement.subject().subsegments()[i]);

Graph

var graph = xdi.graph();
graph.root().context("=markus", true).context("<#email>", true).context("&", true).literal("markus.sabadello@gmail.com");
graph.root().context("=markus", true).relation("#friend", "=joe", true);
graph.root().context("=markus", true).relation("#friend", "=drummond", true);
graph.root().context("=markus", true).context("<#first>", true).context("<#name>", true).context("&", true).literal("Markus");
graph.statement("=markus<#last><#name>&/&/\"Sabadello\"");
graph.statement("=x/#y/(=a/#b/=c)");

Serialization and Deserialization

var graph = xdi.io.read(string);
alert(xdi.io.write(graph));

Client

var message = xdi.message("$anon");
message.toAddress("([+]!:uuid:8888)");
message.linkContract("$public$do");
message.operation("$get", "[+]!:uuid:8888<#name>");

message.send(
	"http://xdi.csp.org/myxdiendpoint",
	function(response) {
		alert(xdi.io.write(response));
	},
	function(errorText) {							// OPTIONAL
		alert(errorText);
	}
);

Discovery

xdi.discovery(
	"+acmebread",
	function(discovery) {
		alert(discovery.cloudNumber());
		alert(discovery.xdiEndpoint());
		alert(discovery.services());
	},
	function(errorText) {							// OPTIONAL
		alert(errorText);
	},
	['<$https><$connect><$xdi>'],					// OPTIONAL
	'https://xdidiscoveryserviceote.xdi.net/'		// OPTIONAL
