Tomorrow at day 0 of the FIWARE summit there will be a training session about Smart Data Models.
Slides are freely shared here
This training will be delivered face to face.

The Manifesto for Agile Standardization (MAS) describes the 7 principles that we apply to the Smart Data Models program.
0. Don't just standardize, be agile and standardize
1. Do not reinvent the wheel
2. Normalize real cases
3. Be open
4. Don't be overly specific
5. Flat not Deep
6. Sustainability is key
If you want to read the agile standardization manifesto’s complete explanation a one-page document is located at the root of our data models repository.
Not all changes in the data models are reported with a blog post, Twitter dissemination o LinkedIn post. But if you notice there is a widget in the right part of the front page (scroll down till Announcements) where these tiny changes are reported (see the image or browse the front page).
Most of them are issues, suggestions or PR solved thanks to the collaboration of the community. They make the data models better for all.
We cannot say thanks individually to all of them but please feel our gratitude.
You can download all of the tiny annoncements from this simple text file.
Many of the datasets published in open data portals are extensively used elsewhere. Well-maintained portals have managers that document the data structure and provide definitions of the types and contents of every field in these datasets. These are some of the requirements for the successful publication of a new Smart Data Model.
With this simple python script (and others to come) at the utils folder it can be drafted a JSON schema compliant with the Smart Data Models Program contribution manual. It is an early version (not everything is updated) but you can check it out.
– base url of the ODS portal
– dataset_id of the dataset
A draft json schema compliant with Smart Data Models Program,
some limitations: it does not translate descriptions (required in English)
some data types
It prints the schema and also returns (if possible a file named schema.json)
test it with this command
SDM_OpenDataSoft_schema_converter.py https://data.ameli.fr/ effectifs
The Smart Data Models Program does not define canonically and uniquely the terms used in the data models. There are many ontologies and vocabularies providing solutions to this issue.
For those users of linked data solutions, every subject includes a context.jsonld file (see example) with long IRI for the terms used in the data models. Besides this, the IRI provided are in fact URL to pages with additional information about the term (see example).
not only this but also two services are available on the tools menu on the front page.
- Merging several contexts and detecting conflicts. (for merging several context from different subjects)
- Mapping a context with external ontologies. (mapping a local context from SDM to any external ontology). These are the ones available but more could be easily created on demand.
But when mapping an existing open and adopted standard now it is possible to customize the context generated by using a new file notes_context.jsonld (see this empty example) at the root of the subject. It will replace the automatic IRI for a term with the customized one.
If have approached the Smart Data Models Program (SDM) for the first time and you want to become a contributor there are some technical concepts that you need to know about the elements compiled at SDM.
Once checked this presentation maybe you want to review the contribution manual
After growing in options and service, it was necessary to update the main menu (not only to make it more legible), but also to make it more natural.
Explore the tools section where all the available services are listed together
Documentation contains everything related to the documentation generated at the SDM and that can be necessary for several tasks
About include mostly the same elements (the starting point and FAQs)
Search remains the same because is one of the most used resources
Community for the interconnection between users and contributors.
New data model request to learn how to start
Every data model in the Smart Data Models program can be mapped with external ontologies and there is a service on the main menu to achieve that.
See main menu -> @context -> generate an external @context
After the publication of data models of CPSV-AP now it is possible to map with their URI thanks to the mapping file.
There is a new service for the creation of schema of a data model when the input is a csv payload.
It is available in the home -> Draft a data model -> Create a data model from csv payload
If you detect any issue or you want to make a suggestion, please send it to email@example.com
test it here
There have been updates in these data models
And there will be others, just check the PR and issues in the PR and issues widget on the front page.
