Hi all,<br>
<br>
have someone experiences with VisTrails (VT)? According the discuss on ML<br>
about using it for a workflow builder I have spent some times with VT. And I<br>
started think about using external library or write it without dependencies<br>
on it. As Paolo mentioned:<br>
<br>
"I think we better avoid external dependencies unless necessary.<br>
Furthermore, I do not know VT, but it seems far from production-ready, and<br>
its scope seems to considerably overlap that of QGIS."<br>
<br>
That's right. VT is more than we need and now it's not good for integrated<br>
into another program. For me looks better to write workflow builder without<br>
dependencies, just with using Qt and its Graphics View Framework.<br>
<br>
So what do you think about it?<br>
<br>

<div><br></div><div>Orange is written in Python and provides dataflow analysis through a "connect the boxes" interface similar to the ArcGIS model builder. There could be some good ideas there that QGIS can adopt.</div>
