I will circulate an announcement when it is running again. Meantime, use this address. Is there one place that develops all the properties of factorization systems? We are especially interested in the non-strict case, that is in which the right factor needn't be epic, nor the left factor be monic, but the unique diagonal fill-in condition holds.
