Abstract:	We will soon be facing a new generation of facilities and archives dealing with huge amounts of data (ALMA, LSST, Pan-Starrs, LOFAR, SKA pathfinders,…) where scientific workflows will play an important role in the working methodology of astronomers. While the traditional pipelines tend to produce exploitable products, scientific workflows are aimed at producing scientific insight. Virtual Observatory standards provide the tools to design reproducible scientific workflows. A detailed analysis about the state of the art of workflows involves languages, design tools, execution engines, use cases, etc. A major topic is also the preservation of the workflows and the capability to replay a workflow several years after its design and implementation. Discussions on these topics are being held recently in IVOA forums and are part of the work that is being done in the Wf4Ever project. The purpose of the BoF was to present to the community the work in progress at the IVOA, collect ideas and identify needs not yet addressed.
