SeismicTraceData - property names are very similar to one another, hence may be confusing. Please consider renaming one
CreateionDateTime - Date that a resource (work product component here) is formed outside of OSDU before loading (e.g. publication date). This refers to when the SegY file was actually produced by Interpretation program, Processing company or even during modern day acquisition.
As you know, there is also the audit trail fields createTime and createUser - to indicate when the record was created in OSDU Data Platform/instance and by who.
As you can see these properties look very similar and some user may make mistake unknowingly. CreateionDateTime and createTime
Please consider changing the first name as that is very specific to this work-product component.
