Today Panasonic contributed an implementation of the OpenDOF Data Transfer Library in C.
The C Data Transfer Source Library provides an API to send data using the OpenDOF protocols to a Data Transfer Sink. This component provides the C libraries for developing applications for transferring arbitrary device/object data. Panasonic will continue to contribute code over the next months.
