This is the project I worked on during my period of work experience in Makina Corpus.

The module named 'plomino.dominoimport' is able to import files in Domino XML Language (DXL), itselves exported from a Lotus Domino database. Coded in GPL license, it can be added as a Plone product, then a tab will be added to Plomino to provide this new functionnality.

At this time, the module is in alpha version, and some features can be not completely implemented, like the import of binary files in forms and documents. However, it's able to import successfully views with their columns, forms with complex fields as selection type, and also documents.

You can find the egg on pypi:
http://pypi.python.org/pypi/plomino.dominoimport

And the updated sources are avalaible in a branch in sourceforge plomino svn repository:
http://plomino.svn.sourceforge.net/viewvc/plomino/branches/ehelly/plomin...

Of course, bug reports, documentation or code contributions are welcome.
