NOMAD's JSON Mapper plugin

This is a plugin for NOMAD which allows to create mappings from JSON into NOMAD schemas and parse the suitable JSON data files accordingly.

The plugin allows to create specific JSON files which specify the mapping of data into NOMAD schemas. These mapper files are identified by the presence of the key json_mapper_class_key.

JSON data files are identified by the presence of the key mapped_json_class_key. If a mapper with the same key value exists, the data will be parsed into NOMAD entries according to the mapping.

Getting started

nomad-json-parser can be installed to your oasis via the steps given in here.

Setting up your OASIS

Read the NOMAD oasis documentation for details on how to add the plugin on your NOMAD instance.

You don't need to modify the nomad.yaml configuration file of your NOMAD instance, beacuse the package is pip installed and all the available modules (entry points) are loaded. To include, instead, only some of the entry points, you need to specify them in the include section of the nomad.yaml. In the following lines, a list of all the available entry points:

plugins:
  include:
    - "nomad_json_parser.schema_packages:json_mapper_schema_package"
    - "nomad_json_parser.parsers:json_mapper_parser"
    - "nomad_json_parser.parsers:mapped_json_parser"
    - "nomad_json_parser.schema_packages:example_schema_package"
    - "nomad_json_parser.example_uploads:example_upload_entry_point"
