Scan meta: handle empty categories
@pithan @sole If the scan meta category is empty, should I still save it? For example if I have scannode.info["notes"] == {"NX_class": "NXcollection"}
. This will save and empty /entry/notes with the attribute NXcollection. Skip it or keep the empty group?
Also @sole, could you tell us again how we should save the notes? We discussed this on-the-fly in December but I'm not sure anymore what the final decision was. NXlog does not seem fitting ("Information recorded as a function of time"). We can have an NXcollection that contains several NXnote's with @type:"text/plain"? Should I check this structure before saving so the notes do not get abused for other things or trust whatever I receive from Redis?
