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.

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:
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.
Now it is based on a responsive interface with these options:
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.
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)
New data models for
available at its own repository in the Cross-sector domain.
Thanks to stbnrivas for its migration from previous project Synchronicity
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)
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’
http://data-models.fiware.org/index.php/submit-an-issue-2/
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.
There is a new widget on the front page titled “Open PR and issues” there you can browse all the Pull requests contributed by the community and the open issues across all the data models.
Updated every 5 minutes
This way you can be informed about evolution going on and to make sure that all contributions are considered.
Although there are not data models coded yet (hopefully there will be new ones coming), just to let you know new subjects are.
– Battery inside the Cross Sector domain
– Green Energy inside the Smart energy domain
– Autonomous mobile robot inside de Smart robotics domain
