As you know I am the main developer — and unique developer, I hope more people will be interested in the future — of the pyxser project. It has a very specific purpose, but it is the only stand alone Python Object to XML serializer that exists. There is also the serialization routine built-in in the lxml extension. The project is hosted on Source Forge, not popular as Git Hub does, but it is a well known project hosting site. The fact is that it is linked from sites and recommended along the Internet by some people. It provides a nice serialization model that allows you to standardise the XML serialization.
It has been downloaded by many people from different sources where it is distributed, reaching about 8.000 downloads from different locations. That makes me very happy, because it is being tested and used widely in real world applications.
Is a real pleasure to know that it is helping in the development of many applications. Also some other projects like jquery-validators it’s being downloaded over 3.000 times. I think that the best features of pyxser, is the fact it can do circular and cross referenced serialization without crashing. Remember that .NET and Java does not support circular and cross referenced XML serialization, so I have reached the right serialization model with pyxser. I have plans to migrate the serialization model and algorithm to other platform, like Java.
