{{#eclipseproject:technology.higgins}} The IdAS XDI Engine is a web application that exposes a Higgins Context as an XDI endpoint, which can receive and process XDI messages.
It maps incoming XDI messages to IdAS operations, which are applied to the Context that is being exposed. This mapping is described in further detail at IdAS XDI Mapping.
Implementation
The IdAS XDI Engine is implemented using the XDI4j general-purpose XDI library. It is an XDI4j "Messaging Target", i.e. an implementation of the MessagingTarget interface. In XDI4j, a Messaging Target is a class that can process XDI messages and produce result XDI documents.
Example Uses
Get everything about an Entity in an LDAP directory.
=sender $get / =(uid=hummel,ou=identities,dc=higgins,dc=eclipse,dc=org)
Get only a single Attribute of that Entity.
=sender $get / =(uid=hummel,ou=identities,dc=higgins,dc=eclipse,dc=org) +(http://www.eclipse.org/higgins/ontologies/2006/higgins/ldap#attr_cn)
Request a new context to be opened:
=markus $get$a$context / $(@parity*contexts/($context)*(+ldap)*(+poc)) $username "un" $password "pw"
