Subject Re: ODF Toolkit Incubation Pre-Proposal
Date Tue, 28 Jun 2011 08:46:37 GMT
Hi Rob,

i support your idea and i think that it make sense to move the ODFToolkit
project to Apache as well.

ODF is a key element in an open standard based world. Probably more
automatically processed  document workflows become available in the future
because of an open standard that everybody can read and write. Fat client
applications like OpenOffice, LibreOffice, Symphony are only one part of the
story. But when we think about the new generation of devices (smartphones,
tablets) it becomes obvious that a smaller library that can handle this
document format really make sense. Simple viewers are necessary to make the
format popular like PDF for easy exchange of documents. Other applications
that generate documents in a backend or again full featured or simplified
editors are altogether necessary to build a working eco-system around ODF.

I would prefer a new project to give them the visibility it needs. Ideally
the project will not only support a Java library but also other languages
(e.g. Python, the existing C#, etc.).
