The restrictions on dataflow name is roughly the same as those on port
names and processor names. Currently there's not a way in the 2.0 UI
to change this dataflow name (as it's not used for much) - so did you
generate this workflow - or is it translated from Taverna 1? As your
'id' is not a proper UUID I guess you generated it..
I must admit I'm not totally sure why we need these dataflow,
processor and port name restrictions - but I guess at least ":" could
confuse process identifiers. Additionally the graph is generated using
dot (graphviz) and SVG - and some funny characters here might not be
properly escaped.
Here's the regular expression used by the 'Rename processor' dialogue
to check for a valid name:
[\\p{L}\\p{Digit}_.]+
Note that if you are thinking about the workflow Title (together with
Description and Author - as shown in 'Details' for the workflow), this
is set as an *annotation* on the dataflow, with a rather elaborate
serialisation:
<workflow xmlns="http://taverna.sf.net/2008/xml/t2flow";
