The tutorial discusses a series of simple\nlinked-data data models based around the supermarket chain’s store finder application, and demonstrates how to design\nmodels holding one-to-one, one-to-many and many-to-many relationships. This **NGSI-LD** tutorial is a direct analogue to\nthe earlier _Understanding Entities and Relationships_ tutorial (which was based on the **NGSI v2** interface). The\ndifferences in relationships created using **NGSI v2** and **NGSI-LD** are highlighted and discussed in detail.\n\nThe tutorial uses [cUrl](https://ec.haxx.se/) commands throughout, but is also available as\n[Postman documentation](https://www.postman.com/downloads/).\n\n# Start-Up\n\n## NGSI-LD Smart Supermarket\n\n**NGSI-LD** offers JSON-LD based interoperability used for Federations and Data Spaces. To run this **NGSI-LD** tutorial for **NGSI-v2** developers, use the `NGSI-v2` branch.\n\n```console\ngit clone https://github.com/FIWARE/tutorials.Relationships-Linked-Data.git\ncd tutorials.Relationships-Linked-Data\ngit checkout NGSI-v2\n\n./services create\n./services start\n```\n\n| [![NGSI LD](https://img.shields.io/badge/NGSI-LD-d6604d.svg)](https://www.etsi.org/deliver/etsi_gs/CIM/001_099/009/01.08.01_60/gs_cim009v010801p.pdf) | :books: [Documentation](https://github.com/FIWARE/tutorials.Relationships-Linked-Data/tree/NGSI-v2) | \u003cimg src=\"https://cdn.jsdelivr.net/npm/simple-icons@v3/icons/postman.svg\" height=\"15\" width=\"15\"\u003e [Postman Collection](https://fiware.github.io/tutorials.Relationships-Linked-Data/) |  ![](https://img.shields.io/github/last-commit/fiware/tutorials.Relationships-Linked-Data/NGSI-v2)\n| --- | --- | --- | ---\n\n---\n\n## License\n\n[MIT](LICENSE) © 2019-2024 FIWARE Foundation e.V.\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffiware%2Ftutorials.relationships-linked-data","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ffiware%2Ftutorials.relationships-linked-data","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffiware%2Ftutorials.relationships-linked-data/lists"}
