Pseudo code for SyncTarget method:

sourceDigest = get_digest_from_feed(syncSource)
targetDigest = GetDigest()

for each entry in syncSource:
  gcon = retrieve_contact_from_google (entry)
  if gcon == null:
    create_google_contact(entry)
  else:
    if gcon.etag == entry.etag or conflict_win(sourceDigest, targetDigest, gcon, entry):
      update_google_contact(gcon, entry)
    else:
      store_conflict_diagnosis(entry)
