# A Semantic Model for Enhancing Data-Driven Open Banking Services
## Appendix A  
This appendix section includes anonymized fragments of the data returned by the open banking API. The snippets show the structure and fields that define the documents in JSON format. The data includes information identifying the customers and the movements associated with the banking products contracted by the customer with the bank. ```
{  \"customers\":[  {  \"_id\":\"A18 XXXXX\",  \"address\":[  \"LUIS PASTEUR 29071,MALAGA,MALAGA,SPAIN\"  ],  \"document\":\"A18 XXXX\",  \"birth_date\":null,  \"names\":\"EXAMPLE SA\",  \"phones\":[  \"g*=*500\",  \"g*=*063\",  \"g*=*062\",  \"g*=*010\"  ],  \"accounts_obj\":[  {  \"id\":\"ESXXXXXXXXXXXXXXXXXXXXX5\",  \"participation\":\"Titular\"  },  {  \"id\":\"ESXXXXXXXXXXXXXXXXXXXXX0\",  \"participation\":\"Titular\"  }  ],  \"emails\":[  \"c****=*0*****.es\"  ]  ]  ] } }
