IFCTool: Discussion: mapping of properties

[Adrian62D]

Copied from a draft spec we have. I guess it would make more sense to aim for a separate tool to cover mapping instead of merging this into ifctool. Nevertheless I am recording this here since it is a related topic.

Also I believe the tool should not be a generic "json mapping" tool but should be specific to ifcjson so that we can have specific parameters geared towards this use case.

ifcjsonmapper

Implement a command-line tool that provides the functionality described below.

ifcjsonmapper <inputfile> <outputfile> [--mapping <mappingfile>]

Example:
ifcjsonmapper input.json output.json --mapping mapping.json

Behavior:

• The tool expects a valid ifcJSON-4 file as inputfile
• The tool optionally expects a valid select-transform template as mappingfile
• The tool provides a valid ifcJSON-4 file as outputfile

Remarks:
Reconsider/evaluate if is select-transform is the proper library for the job.
