<div dir="ltr">Hi Victor,<div><br></div><div>ARL and Kitware are the primary developers of Xdmf, but everyone is invited to contribute to the project.</div><div><br></div><div>Yes xdmf3 has not yet replaced xdmf2 within ParaView. The binaries for the next ParaView release (the release candidate should have it) will have both turned on. Over the next few releases xdmf2 will be deprecated and then removed from ParaView.</div><div><br></div><div>xdmf itself can be built apart from VTK. On the xdmf wiki there are links to the repositories that you can check out to build it standalone. What you see in VTK/Thirdparty is a clone of parts of that standalone library. The VTK interface to it is in VTK/IO.</div><div><br></div><div>hth</div><div><br></div><div><br></div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature">David E DeMarle<br>Kitware, Inc.<br>R&D Engineer<br>21 Corporate Drive<br>Clifton Park, NY 12065-8662<br>Phone: 518-881-4909</div></div>
