Hi Lucian,

The basic C++ should have two functions for each member attribute,
named after the attribute; one with no arguments, which returns the
value of the attribute, and one with one argument which sets the value
of the attribute.

So, to set the name you would call
model->name(L"modelname");
And to get the name, you would call
model->name();

These specific functions are located in
./sources/cellml/CellMLImplementation.cpp

Different bindings have different conventions; in the Java binding, we
use setX and getX methods for attribute X. In the XPCOM binding we
have setX and getX as well, but they both take pointers to a container
as arguments, and return status flags. I hope this helps.

As far as a recommended approach to loading files goes, in the test
cases for the API, we assume we are given a URL. In OpenCell, we
resolve file locations into URLs. Depending on the libraries you are
using, converting file locations into URLs or pulling out the text
from a file yourself may be trivial or annoying; we use whichever
method is least annoying at the time, which is usually resolving the
file location into a URL, unless we are dealing with models that only
exist in ram.

Best Regards,
Justin.
