The NGOSS Thru XML Interface Implementation Specification (IIS) is a summary of the catalyst project shown in the Long Beach TMW Catalyst Showcase.  Pannon GSM has launched an Enterprise Application Integration program. This program consists of multiple related projects. One of these project's goal was to create reference architecture for application integration. The reference architecture was defined based on a Service Oriented ArchitectureA computer systems architectural style for creating and using business processes packaged as services, and the SID [TMF SID 3.5] was chosen as a candidate for the common data model for the services. 

Customer data is stored in three major legacy systems: SAP, Pandocs and ABC. We need to have a service that is aggregate data stored in these systems and provide a single view of customer that could be a SID compliant schema.

Therefore this project aimed at the following:

The project must serve as a basis for evaluating the following concepts in the Composite Application Reference Architecture:

• Determine the applicability of TMF's SID model as the canonical data model for customer data.
• The usefulness of Business Entity Services concept: feasibility of implementation, usability
• The project must create a service that – when integrated with the CRM front-end systems (out of scope) – will prevent the issues currently arising from out-of date customer data. The service will provide data that is current enough to serve the business needs.
