OpenPDC or openHistorian?

The seem to do the same tasks. They look the same. Are both going to be worked on or will they converge at some point?

The openHistorian 2.0 has been a very ambitious project that has been in development for over 2 years. At it's core, it is a flexible API engine that has to be wrapped around something. Rather than delivering the core openHistorian engine, we decided to wrap it inside the Time Series Framework. Who want's a historian that cannot connect to a C37.118 stream anyway? In order to get something into the hands of users, we copied much of the GUI / Configuration interfaces that people are used to in the openPDC product. As this products matures, you will see a divergence of openPDC and openHistorian as additional configuration options will be exposed to the user.

It is possible to see a limited purpose historian 2.0 option inside openPDC. But primarily, your options will be to set it up as an action adapter within openPDC (since it will be used for archiving and temporal processing).

That being said. Realize that this is only an alpha. We have not decided yet how much we want to separate the PDC functionality from the Historian functionality. So don't go crazy treating the openHistorian as a PDC since some of this functionality may be removed by the time the Beta is released.
