Yes, by using the ImageIO framework. Something like this:
CGImageSourceRef imageSource;
CFDictionaryRef metadata;
if((imageSource = CGImageSourceCreateWithURL(myImageURL, 0)))
{
if((metadata = CGImageSourceCopyPropertiesAtIndex(imageSource, 0, 0)))
{
// the metadata dictionary should contain all
// the Exif data you need, including make and model.
}
CFRelease(metadata);
}

It's not the data universe only, it's human conversation.
They want to turn it into a one-way flow that they have entirely
monetized. I look at the collective human mind as a kind of
ecosystem. They want to clear cut it. They want to go into the
rainforest of human thought and mow the thing down.
