the first question is by far out of scope from my knowledge reading the german wikipedia articles de veda the english text is very similar veda on it my understanding is the following there are four vedas rigveda samaveda yajurveda atharvaveda bhagavad gita is in the english and german wikipedia articles listed under other scriptures and smriti respectively from my limited understanding i would conclude that the text is not a vedic text in the narrow sense of vedic however it seems to me that the term vedic sometimes is used in a broader sense basically meaning something like knowledge in this sense it might be possible to classify the text as vedic from what i read from a few more sources i would not put it under vedic text but as i said in the beginning i know so little about these things that no one should rely on it mmh better i start thinking about your second question best regards
