Since the first realization of scanning tunneling microscopy (STM) and scanning tunneling spectroscopy (STS), a wide range of applications has been developed by using the technique of quantum tunneling effect. The community aims at organize experimental data along FAIR principles, thereby developing or using a standard vocabulary of metadata. NeXus allows to generate such a sort of data modelling and with that we have developed specific data model called NX_sts for STM/STS experiment. Our work focuses not only on storing data and metadata from STM/STS experiments in terms of the NX_sts vocabulary but also supports handling data-analysis results. In this presentation, we will show how metadata can be converted into the NeXus data format. We will detail the basic software architecture of reader that transforms metadata file into STM/STS specific data model which in terns follows NeXus data format concepts.
