Year of contribution at the CONTRIBUTORS.yaml

All the CONTRIBUTORS.yaml files across all subjects have been extended with a new attribute year. This year means the year of the contribution.
It will help us to give recognition to the contributors.
By default, it has been set to 2022 (it was much work to find out when the last contribution was submitted for each one of the several contributors across the 60 subjects).

It has been also changed in the template of the CONTRIBUTORS file in the templates folder.

Contributors: Updated the service for checking your schema

In order to create a new data model or to update an existing one, Check your schema before contributing it, to check the schema on the front page.

The service has been updated to check not only the attributes of the payload but also the schema metadata (schema version, license, derivedFrom, title, description) so it will be easier to complete it before submission.

The code is available at the directory utils in the data-model repository.

MAS: Manifesto for Agile Standardization

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.


Announcements widget. Just thanks

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.

Just thanks

Connecting Open Data Soft open data with Smart Data Models for drafting new data models

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 effectifs


New customization option for context

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.

  1. Merging several contexts and detecting conflicts. (for merging several context from different subjects)
  2. 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.

Help to early contributors

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
