Data2neo

The library can now support parallel relations of the same type, by using the GraphWithParallelRelations from the new py2neo_extensions module. Other minor upgrades in converter to handle the new semantics/syntax.

The first version of the documentation is finished.

Full wrapper classes can now be created and registered with register_wrapper.

Fixed bugs in core code, mostly related to state recovery and multithreading.

The converter can now persist its state (this is primarily targeted at jupyter notebooks). If an exception is raised and caused from external factors, they can be solved and the converter recalled. It will remember where it has stopped and will continue there.

Also slightly better logging and other minor updates.

Initial Version of the rel2graph library.
