# Integration in the bigger puzzle

## Synergies with other dynamics

<figure><img src="image_86.png" /></figure>

Good news : several organizations are involved in all those various dynamics at once which helps align planets
# Conclusion

Quite en endeavor !

* However, all those dynamics

* have decent time to work

* build on

* international FAIR practices

* & open-source implementations

⇒ Better chance to contribute to the overall community
