I found the following hint:
A critical edition of The Cave of Treasures is available in Syriac with an accompanying French translation in the Corpus Scriptorum Christianorum Orientalium: La Caverne des trésors: Les deux recensions syriaques, ed. Su-Min Ri, CSCO, 486–7, Scriptores syri, 207–8 (Louvain: Peeters, 1987). For the sake of clarity, I have sometimes abbreviated passages cited from this work.
The article by Su-Min Ri referred to is ‘La Caverne des Trésors et Mar Éphrem’, in Orientalia Christiana Analecta 256 (1998), p. 82f.
So I went to Factbook, which seems to have no entry for this. Instead, an ALL Smart Search pointed towards

(right panel). Maybe there could be added a Factbook entry?
