Next 12th of June 17:00 we will have a 1 hour session during the FIWARE summit in Vienna.

The session will be a group of short presentations (<12 min) about actual use cases using Smart Data Models.

Fill out the form if you are willing to participate as a speaker

In the context.jsonld of every subject there are long IRI for every first-level attribute and for the names of the entities. See this example.

formerly the link of the attributes took you to an existing web page while the links of the entities take you nowhere. Strictly there is not need to take anywhere, however, it would be useful to create such pages with basic information. Now there are also links to the entities’ pages, where a new page is being created. See this example.

Now all of them have their own page with these sections

• Definition
• Version
• Original Schema
• Contributors of the Subject
• Adopters of the data model
• Examples of the data model
• Attributes of the entity
• Required Attributes

See here the example for the data model Anomaly.

We have released a master sheet that simplifies the contribution to the smart data models.

It uploads the data model to a new repository called drafted.

The video help is also available

Steps for using the spreadsheet

0.- Make a local copy in your google account and grant permission the first time you use it (it warns you that it is not validated by google, true, but anyhow go to advance and grant the permissions

1.- Include your example in json key values

2.- Include the name of the data model, its title, the subject, and the description together with your email

3.,- Describe the attributes, their NGSI type, their data type, and the written description.

And click on the two buttons

We have noticed an error in the description of the attribute location in the file common-schema.json, a file that is embedded in most of the data models. It does not affect the data types (so the validation of the schemas is not affected) but it affects the qualification of the NGSI type that it is not properly identified,

GeoProperty is written with capital middle P.

The file has been updated and soon it will be launched an update of all the data models affected.

New options for pysmartdatamodels package. There are a new element in he tools menu to access the pysmartdatamodels package, its documentation, or a code example.

Some of the data models available are generated according to some ontologies (like dataModels.OSLO). The @context provided for the subject includes IRIs with the smartdatamodels by default, however, the use of official ontologies can be required.

In order to allow this the file notes_context.jsonld was created and also included in the contribution manual (seection 1.5 slide 23).

Now the service for mapping the external ontologies (Home -> tools -> Mapper @context with external ontologies) can detect that instead of a regular configuration file a notes_context.jsonld is provided and applies the replacement of terms defined there.

It can be also used as an API call, in this link you have an example https://smartdatamodels.org/extra/create_external_referenced_context.php?localContext=https://raw.githubusercontent.com/smart-data-models/dataModel.OSLO/master/context.jsonld&configOntologies=https://raw.githubusercontent.com/smart-data-models/dataModel.OSLO/master/notes_context.jsonld

The structure of the notes_context.jsonld has to follow the template

• {

“@context”: {

“Term1”: “uri_term_1”,

“Term2”: “uri_term_2”,

}

}
