Opening an *.ifc file we can find "File_Schema" in the Header, for example: HEADER; ... FILE_SCHEMA (('IFC4')); ENDSEC;

We are downloading IFC stream file and it would be nice to know the file schema version for it. Is it somehow possible to get this information via DataManagement API?

    It sounds you wanted to know File_Schema before downloading IFC from storage of Autodesk (your own bucket or Autodesk cloud products such as BIM 360)? I do not see such web service/response is available. If the IFC has been downloaded, you can simply open the file and check its FILE_SCHEMA – Xiaodong Liang Nov 30 '18 at 16:58

This is already an old post, but just to mention that for those who download the file before any other operation: once downloaded, the following command can be used (on a Unix-like environment) to get exactly the IFC schema (e.g. "IFC2X3", "IFC4"):

grep "^FILE_SCHEMA" file.ifc | cut -d"'" -f2

Of course this command can be integrated in a program written in Node.js for example (using childProcess.exec), or any other programming language. Note that this is usually faster than streaming the file and searching in it, or even using a language-specific library to "grep" the file, especially for big IFC files.
