JOSIF Main Page | Joint Open Source Interface Framework

Introduction

The JOSIF project is intended to provide tooling to help with the consistent specification, documentation and implementation of large scale enterprise SOA architectures. The tooling is being targeted at Enterprises, Vendors, Systems Integrators and Standards Organisations who would benefit from a model driven engineering approach for consistently managing their enterprise data models and integration interfaces. In the context of the TM Forum it is being used to define standard interfaces derived from the SID model. However we have proposed the tooling to other standards organisations including the ITU SG2 in Geneva, 3GPP and ATIS. The tooling has deliberately been made open source to significantly reduce the barriers to entry and to overcome obstacles to adoption by organisations other than the TM Forum and the initial committers.

The TM Forum are currently specifying each interface using XML. Thus the generated XML is normative and supports a WSDL Contract-first style of programming. The JOSIF Soap plug-in generates WSDL interfaces according to the Soap 1.1 specification. The rules governing how the Tigerstripe models are mapped to WSDL are documented here on the TIP Soap Generator page.

The build system for each interface specification project pulls in the required dependencies (Models and /or pre-generated XML) and combines these with the output from the interface model. The generated WSDL is tested for usability using a common wsdl2java generator ( Apache CXF ) before being packaged with the Tigerstripe generated documentation and any other documentation into a single packaged specification zip file.
