OCDT Community Portal

Welcome to the portal of the community of Open Concurrent Design Tool (OCDT) users and developers.

The purpose of this portal is to share and exchange information, experiences, models and tools related to concurrent engineering for space applications. In particular, the portal is dedicated to the distribution and usage of the Open Concurrent Design Tool.

A small part of this portal is publicly accessible but a substantial part is only accessible to members of the OCDT Community.

What is the Open Concurrent Design Tool and what does it stand for?

• An initiative of the European Space Agency, and in particular its Concurrent Design Facility at ESA/ESTEC, to create an open software environment for concurrent, collaborative and distributed engineering applied to the development of space systems in the early phases of the life cycle.
• An implementation of the draft open standard defined in the ECSS-E-TM-10-25 "System Engineering - Engineering Design Model Data Exchange (CDF)" Technical Memorandum.
• OCDT has a three tier client-webservices-server architecture and consists of the following main components:
  • ConCORDE (Concurrent Concepts, Options, Requirements and Design Editor), the main end-user client tool that is implemented in C# on top of MS Excel 2010.
  • Web Services Processor (WSP), implemented using the open source nodejs scalable network application platform.
  • Persistent Data Store (PDS), implemented using the open source PostgreSQL relational database management system.
• A future platform for exchange and near-real-time sharing of concurrent engineering models in order to enable distributed concurrent design sessions.

This portal currently provides the following:

• Information on ECSS-E-TM-10-25 "System Engineering - Engineering Design Model Data Exchange (CDF)", including its electronic annexes
• OCDT Software Downloads area
