Extension of the Smart Data Models

Hopefully you have unnoticed about several structural changes this weekend that has happen at SDM.

Database of attributes,

Now there are several additional information included.

— A unique id for every attribute of a version of a data model (i.e.

— The link to the parent’s attribute (whenever there is a parent) context link (i.e. https://smartdatamodels.org/address)

— The unique id of the parent attribute (whenever there is a parent) (i.e.

— The @context link of the attributes pointing to an existing web page with some details about the attribute (i.e. https://smartdatamodels.org/postOfficeBoxNumber)


Now the second level of attributes is available in the specification document for all the languages (i.e. https://github.com/smart-data-models/dataModel.User/blob/master/Activity/doc/spec.md)

Context file

Now the second and subsequent levels of the attributes have URI entries in the @context included in the file context.jsonld file in every subject (i.e. https://github.com/smart-data-models/dataModel.Environment/blob/master/context.jsonld)

The URI of the data models points to a existing web page (i.e. https://smartdatamodels.org/dataModel.Environment/ambientNoiseTSA)

Besides this we welcome a new member of the SDM team, Rihab Feki.

Simple but useful programs to interact with a broker in PHP

We have released two very simple programs to create an entity in a context broker and for removing an entity based on its id.

Although this is pretty straight forward, being coded in PHP allows you to integrate with, in example, in a WordPress site.

In fact these programs are working in the test Orion-LD broker option, located here at home -> tools -> test Orion-LD broker

The source code is available at the utils directory and the  data-models umbrella repository
