[Qgis-psc] Proposal that QGIS.ORG will become a member of the OpenDesign Alliance

[Andreas Neumann]

Hi Strk,

If there would be a good GPL based DWG library I would happily propose 
to use it - but unfortunately there isn't. The only partially viable 
alternative is the LibreDWG library 
(https://www.gnu.org/software/libredwg/) which hasn't received an update 
since 2009. Investing in that solution would probably mean an investment 
of a medium six-figure amount in Euros and then more to keep it alive. 
Unfortunately, unless a viable sponsor comes in, this isn't a solution.

Do you know other alternatives?

About the license: it would be the plan to develop a separate (non GPL) 
app/service that uses Teigha. A QGIS CAD Plugin can then connect to this 
service and get access to that CAD data. Jürgen has thought about that. 
As such, it wouldn't be an integral part of QGIS and QGIS can be 
distributed with or without the Teigha library.
