I have my own separate mathematical analysis and control software written in cross-platform C++ and I would like to access tags/tag data from OpenSCADA and make control requests.
Note I have configured OpenSCADA to provide an OPC UA interface but I have no OPC UA client software to access this interface.
Other OPC UA servers provide client SDK libraries to access OPC UA server tags. I would like to be able to get the tag tree, get tag parameters / values, etc. in a way that is similar to other SDKs.
Do you have an equivalent OPC UA client SDK library. If not, what would you recommend that I do?
In general, what is your recommended approach to externally access OpenSCADA tags and tag data?
Thanks for your insight.

Yes, OPC_UA implementation into OpenSCADA already moved to library and here independent client's test using program placed: http://oscada.org/svn/trunk/OpenSCADA/src/moduls/daq/OPC_UA/libOPC_UA/

Here more variants had but all exact network based for different protocols up to self implement.
Learn, learn and learn better than work, work and work.
