In our Twitter account @smartdatamodels now it will be twit twice a day (9:00 and 15:00) a link with the chosen data model of the day. Follow

Enjoy!!

The creation of a data model requires two mandatory files, one example and a JSON schema containing the definitions and data types of the elements in the entity.
However, the JSON schema creation could be somehow demanding.
The new tool opens the door for people with only basic knowledge of JSON (every FIWARE user should be proficient in it).
If you have an entity defined in your system just retrieve it in key values format and paste it in this form (available at Menu -> Draft a data model -> Generate your schema out of your payload.

It will return a new page with a raw version of a JSON schema. What you have to check for a final submission?

1.- The title and description of the overall schema

2.- The id address of the schema (you’d need the subject to locate it)

3.- If you want to include any tags

4.- Remove those definitions that does not match your data model and include the missing ones.

so you would be able to make a PR with this JSON schema and your example according to the contribution manual.

Check it here as well

In the root of every subject in the Smart Data Models program there is a file named

context.jsonld (example from environment subject)

It compiles long IRI for every term in the subject (But for those which are general terms).

their URLs match this pattern “https://smartdatamodels.org/ ‘subject’  / term”

e.g.  “aqiMajorPollutant”: “https://smartdatamodels.org/dataModel.Environment/aqiMajorPollutant”

Now all of them are existing pages with basic information about the term.

https://smartdatamodels.org/dataModel.Environment/aqiMajorPollutant

GSMA in their Iot Big data project has created an ontology for mapping some of the elemtens in the data models.

Now in the folder

data-models > context -> ontologies_files ->gsma.json you have the file you can use with the external @context generator service in the main menu.

Now in the documentation directory of every data model ‘/doc’ you can see two new files spec_IT.md and spec_JA.md that are the Italian and Japanese translations of the specifications.

They are in beta version, (and they are nice automatic translations, but automatic).

The new service for the generation of externally referenced @context has now available the mapping of the 13 SAREF ontologies.
Check them out in the ontologies_files directory in the data-models repo.

If you want to use data models coming from several subjects you will have to merge (somehow) their @contexts.

In this first step, we offer you a service that allows you to choose what subjects you need to merge and to generate the @context.

See the instructions on the page. Now in Main menu -> @context -> Generate a local context

It also provides you with the conflicts in the attributes’ names, in order to let you solve them manually.

In the next step, possibly next week, you will have another service that will allow you to choose what reference ontologies and vocabularies you want to use and replace the Smart data models IRIs with those coming from these external sources.
