Introduction
QTI (Query & Test Interoperability) is the IMS specification for assessment
Last versions: QTI 2.0: items (questions) QTI 2.1: tests
Need for open source service-based implementations: Authoring tools Management systems (engines/players)

APIS engine
Assessment Provision through Interoperable Segments
Supports QTI 2.0, but only some types of interaction (types of questions)
Web Services-based interface Developed by University of Strathclyde
JISC Project: http://www.jisc.ac.uk/whatwedo/projects/apis.aspx
Available at SourceForge: http://sourceforge.net/projects/apis/

Objective of our work
Extend APIS to support: More interactions types (types of questions) More datatypes (of variables) More types of expessions (to obtain the
corresponding result)
Assessment tests (QTI 2.1): Internal structure of tests: sections and parts Processing the outcome for the whole test
