It is certainly possible to iterate over the full metadata of an OpenEXR file.
Imf::Header *header = ...;
for (Imf::Header::ConstIterator hit = header->begin();
hit != header->end(); ++hit) {
std::cout << "name = " << hit.name()
<< ", type = " << hit.attribute().typeName() << "\n";
}
For a full example, look at this portion of the OpenImageIO code:
https://github.com/OpenImageIO/oiio/blob/master/src/openexr.imageio/exrinput.cpp
look at the loop beginning at line 530.
