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, 3.1, 3.2 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.

New version of contributors file

  By , , , , , , , , ,

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.

Updated the attributes search data base

  By , , , , , , , ,

In order to create a new data model is always interesting what others have done in order copy and to maintain interoperability.

That’s why we have available a database with all attributes and enumerations across all data models.

Now it’s updated daily and the number of occurrences is also available.

What’s is your opinion of the new specification model?

  By , , , , , , , , ,

We are testing a potential new format for the specification that

1) makes easier for people to read the specification

2) provides additional utility to be connected with other platforms making NGSI more compatible

Could you check these two new specifications Building, BuildingOperation compared with the old two Building, BuildingOperation and gives us your opinion?

(once in, click on the name of the object for deploying all the content)

[cf7form cf7key=”new-specification-format”]

The actual new specs are here without viewer (building, building operation) what you see above is generated automatically from the yaml specs.

What’s the idea behind adopting yaml specifications? To allow multiple evolutions (automatic multilanguage spec, integration with other platforms, etc)

Help for data modellers

  By , , , , , , ,

Some of the contributors have requested some help about creating new data models. How to do it and where to do it.

HOW TO CREATE DATA MODELS

1) If you are clear about the payloads that you want to share (you have a plain key values json payload)

i.e. https://raw.githubusercontent.com/smart-data-models/dataModel.Weather/master/WeatherObserved/example.jsonld

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

to generate a draft version of the json schema. You will have to review (for sure).

– Whether you need some restrictions (min, max) on number properties

– The number of required properties

– The full list of options in enumeration properties

– Remove the context (it is treated as property)

– Check the Arrays (minItems, etc)

and possibly some other minor issues

WHERE TO CREATE DATA MODELS

3) We offer an open repository named pending for you to contribute while developing. Ask for access raising an issue with the option ‘Access to pending repository’

Documentation status for all data models

  By , , , , , , , ,

Every day will be checked the documentation available for each data model and the result is dumped in the file documentationStatus.json

It would help a user to identify all the documentation, examples, schemas and specification available and it allows an automated use for any other purpose.

Check it out.
