Which online resources (preferably open source / cc) does contain info on which Chinese verbs is separable? Some Chinese verbs are separable (also called verb-object compounds), that is:


  他今天上三個鐘頭的課　(He/she had three hours of class today)


Where 上課 is a separable verb.

As there is no rules on which verbs are separable and not, I'm looking for an online resource where I can look that up. For example, does CC-CEDICT contain info about which verbs is separable and not?
The Pleco app contains this information. It was actually confusing me for a while, but the //'s in the pinyin indicate verb separability. Pleco includes some free dictionaries, but it also allows you to download others for a price. I'm not sure if the verb-separation indications are tied to any particular dictionary.
