Some of the contributors have requested some help about creating new data models. How to do it and where to do it.<\/p>\n

HOW TO CREATE DATA MODELS<\/p>\n

1) If you are clear about the payloads that you want to share (you have a plain key values json payload)<\/p>\n

i.e. https:\/\/raw.githubusercontent.com\/smart-data-models\/dataModel.Weather\/master\/WeatherObserved\/example.jsonld <\/a><\/p>\n

2) You can use this tool https:\/\/www.liquid-technologies.com\/online-json-to-schema-converter<\/a> (This link is always available in the Learning Zone<\/a> on the upper menu, section tools)<\/p>\n

to generate a draft version of the json schema. You will have to review (for sure).<\/p>\n

– Whether you need some restrictions (min, max) on number properties<\/p>\n

– The number of required properties<\/p>\n

– The full list of options in enumeration properties<\/p>\n

– Remove the context (it is treated as property)<\/p>\n

– Check the Arrays (minItems, etc)<\/p>\n

and possibly some other minor issues<\/p>\n

WHERE TO CREATE DATA MODELS<\/p>\n

3) We offer an open repository named pending for you to contribute while developing. Ask for access raising an issue<\/a> with the option ‘Access to pending repository’<\/p>\n
