COMET is the new name for what was previously called the CDP4. We are transitioning the applications and software libraries. The code and documentation will still refer to CDP4 in a number of places while we are updating.
COMET® is the RHEA Group Concurrent Design Solution that allows a team of engineers to perform Concurrent Design. Concurrent Design is a methodology that is applied to the design of complex multidisciplinary systems. Concurrent Design is a design approach in which all design disciplines and stakeholders are brought together to create an integrated design in a collaborative way of working. COMET® is used to collaboratively create a design that is shared by means of a central repository that is the single-source-of-truth. The COMET-SDK Community Edition is a software development toolkit that can be used to create Concurrent Design applications. The COMET-WebServices-Community-Edition and the COMET-IME-Community-Edition are built on the COMET-SDK.
The COMET-SDK comprises 8 components:
- CDP4Common
- CDP4Rules
- CDP4RequirementsVerification
- CDP4JsonSerializer
- CDP4Dal
- CDP4JsonFileDal
- CDP4ServicesDal
- CDP4WspDal
The COMET-SDK is an implementation of the COMET Data Model which extends the ECSS-E-TM-10-25A, including Annex A and Annex C. ECSS-E-TM-10-25A is a Technical Memorandum under the E-10 System engineering branch in the ECSS series of standards, handbooks and technical memoranda. ECSS-E-TM-10-25 facilitates and promotes common data definitions and exchange among organisations, which are interested to collaborate on concurrent design, sharing analysis and design outputs and related reviews. This comprises a system decomposition up to equipment level and related standard lists of parameters and disciplines. Further it provides the starting point of the space system life cycle defining the parameter sets required to cover all project phases, although the present Technical Memorandum only addresses Phases 0, A and B1.
The libraries contained in the COMET-SDK Community Edition are provided to the community under the GNU Lesser General Public License. Because we make the software available with the LGPL, it can be used in both open source and proprietary software without being required to release the source code of your own components.

The SDK contains multiple libraries that are each packaged as a nuget and avaialble from nuget.org.
