Determining the children objects content models: mime type of the file with the name OBJ
Compound objects can have children of any content model. There are three ways the compound object batch module can determine the content model of child objects (see issues for the other two ways: #2 (closed) and #3 - separate tasks.)
- from the mime type of the file with the name OBJ; a preliminary mapping from content model to mime type (the reverse of what we need) is available at https://gist.github.com/mjordan/92e9eb263ee1071d8a23. In the case of a compound child object, which has no OBJ datastream, the presence of additional directories can be a reliable indication of its content model.
