Minor update on guidelines

Included two new sections on the guidelines for the Smart Data Models


Whenever possible they will be absolute references in order to provide the ability to use the data models isolated from the rest of documents



The section definitions will be included in the subject-schema.json name of the subject.



Drafted Node data model

This data model, node, is not officially approved but is on the path for becoming a resource for simulation a node inside a digital twin model (See this video) receiving the measures from an array of sensors controlling different properties and to provide these data to several other nodes which can be connected to.

Remember that incubated repository is devoted to the design and test before submitting officially to the Smart Data Models initiative.

You can claim access to this repository in the issue form option access to the incubated repository.


Converted Global Data dictionary codes

What is Global Data Dictionary

The GS1 Global Data Dictionary (GDD) is a repository of the data elements defined across all GS1 Standards.

What is the scope of the Global Data Dictionary?

GS1 Business Message Standards (BMS) and their components with definitions for GDSN 3.1, 3.1.2 , 3.1.3 and 3.1.4, GS1 XML for EDI 3.0, 3.13.2 and 3.3, TSD and EPCIS 1.0.1. Higher versions will be added upon ratification.

  • Business Messages
  • Business Information Entities – message components and the relationship between them
  • Business Data Types
  • Code Lists used in Business Messages

The Business Messages are composed of Business Information Entities that comprise classes of information and their attributes. The attributes, in turn, have data types that may contain code list

The Full Set of GDSN & Shared Code Lists, and the Full Set of EDI, EPCIS, CPV & Shared Code Lists is now in a structured format in json much easier to integrate with NGSI platform.

Soon there will be part of them integrated into the smart data models.

Working with https and improvement in the issue form

1.- It is just a technical improvement but now you can access everything in this site with https://data-models.fiware.org.

2.- The issue form has also been improved with new options but simplified structure.

Check it out and please report any issue.


Simplified the subscription page

The subscription page is being dramatically simplified keeping the same functionality.

Now instead of having different forms for the different mail lists nos it is just a checkbox fo the list you are willing to subscribe.

Remember just one mail once a week.

These are the weekly domains lists unless there is something relevant on any topic.
Select list(s):

New version of contributors file

Every subject had a file named CONTRIBUTORS.md which compiles all contributors to the different data models in this subject. However, from the point of view of the management, it was not a structured format. Due to this, it is going to be replaced with a new file named CONTRIBUTORS.yaml with the same info but structured so we could manage properly and answer questions like:

  • How many contributors collaborate in this subject?
  • How many subjects are being contributed by this person?
  • What organisations are contributing to the initiative?

Now there is also a field for allocating comments.

The format is friendly enough to be simply edited but at the same time, it can be automatically processed.

Next week CONTRIBUTORS.md will be removed from the different repos.

New commons section for data models

There is a new common section, named “DateTime-Commons“,  in the file common-schema.json (the one which is partially included into most of the data models) because it compiles some shared elements (like Location-Commons or GSMA-Commons).
This section includes the first element, which is the mapping into a property (type object) of the schema.org class OpeningHoursSpecification. (see below)

So whenever there is an opening hours specification this would be the chosen format. (It is true that there is a similar property named OpeningHours, also mapped in schema.org) that it is only a text (oriented to be printed more than queried).

It only affects the museum data model that it will be updated after gathering the feedback of the contributors.

The new section included.

“DateTime-Commons”: {
“type”: “object”,
“description” : “All date-time elements in data models unless explicitly stated are ISO 8601 compliant”,
“properties”: {
“openingHoursSpecification”: {
“type”: “array”,
“description”: “A structured value providing information about the opening hours of a place or a certain service inside a place.”,
“items”: {
“properties”: {
“opens”: {
“type”: “string”,
“format”: “date-time”
“closes”: {
“type”: “string”,
“format”: “date-time”
“dayOfWeek”: {
“type”: “string”,
“enum”: [
] },
“validFrom”: {
“type”: “string”,
“format”: “date-time”
“validThrough”: {
“type”: “string”,
“format”: “date-time”
“minItems”: 1

See it in the original file common-schema.json.
