A new data model in the subject Organization, Person, mapped from schema.org.
You can see in the main page an image like the one below.
It takes you to a google spreadsheet where you can draft simple data models even without knowledge of json schema.
Json schema is the format that stores the master description of the data models in the Smart Data Models.
Now there are two additional tabs, ADOPTERS.yaml and notes.yaml which helps you to fill those files which are mandatory to be present but empty if you do not want to disclose your use case or you do not need to add additional explanations about the submitted data model.
Note: if you want to use the spreadsheet you need to:
– Create a local copy in your google account
– Allow the scripts to be executed
– Fill the yellow cells and click on the buttons
Feedback is always welcomed at info@smartdatamodels.org
There is a new service for simplifying the testing of a contribution to a data model.
The new service will check it, just by providing the link to the root of the folder in an publicly accessible repository
all the files (mandatory ones like schema and examples) and the optional (notes.yaml, ADOPTERS.yaml)
There is a specific page for this test in the contribution manual
Every subject — a group of data models — has a file named contex.jsonld at their root.
This file contains the @context with automatically generated IRI for the terms used in the data model.
The Entity types are also available in this file with their long IRI. In the pointed example are the entries for “SeaConditions”, “WeatherAlert”, “WeatherForecast”, and “WeatherObserved”
Remember that if you want to use other IRI coming, for example, from existing ontologies you can use the service on the Home -> Tools -> Mapper @context with external ontologies
Now you can find in pypi.org the python package pysmartdatamodels with 13 functions for the integrators of the data models (more than 800) in external systems and applications. It is a beta version. There is a function, update_data() that whenever is run, it updates the data models to the last version (including adding the new data models). The code is available at the utils directory.
This python package includes all the data models and several functions (listed below) to use in your developments.
If you want to be updated on this package you can join this mailing list (Announcements are sent only when something relevant happens). We love to get your feedback at info@smartdatamodels.org
There are several online tools to manage and to create the data models, generate examples or to adapt to existing ontologies. See the tools menu option at the home site.
1- List all data models. Function list_all_datamodels()
2- List all subjects. Function list_all_subjects()
3- List the data models of a subject. Function datamodels_subject(subject)
4- List description of an attribute. Function description_attribute(subject, datamodel, attribute)
5- List data-type of an attribute. Function datatype_attribute(subject, datamodel, attribute)
6- Give reference model for an attribute. Function model_attribute(subject, datamodel, attribute)
7- Give reference units for an attribute. Function attributes_datamodel(subject, datamodel)
8- List the attributes of a data model. Function attributes_datamodel(subject, datamodel)
9- List the NGSI type (Property, Relationship or Geoproperty) of the attribute. Function ngsi_datatype_attribute(subject, datamodel, attribute)
10- Print a list of data models attributes separated by a separator. Function print_datamodel(subject, datamodel, separator, meta_attributes)
11- Returns the link to the repository of a subject. Function subject_repolink(subject)
12- Returns the links to the repositories of a data model name. Function datamodel_repolink(datamodel)
13- Update the official data model list or the database of attributes from the source. Function update_data()
1.- Create a proper documentation
2.- Function to allow submission of improvements (i.e. missing recommended units or model) and comments to the different data models. Currently, you can do it by searching for your data model here
https://smartdatamodels.org/index.php/list-of-data-models-3/ visiting the github repo and making your PR or raising your issues there.
3.- Function to submit a new data model to an incubation repository. Currently, this is done manually incubated repository. By filling this form you are granted to contribute with new data models.
4.- Include new functions like search for the subject of a data model or other that you can suggest to us at info@smartdatamodels.org
### some example code from pysmartdatamodels import pysmartdatamodels as sdm subject = "dataModel.Weather" dataModel = "WeatherForecast" attribute = "precipitation" print(sdm.list_all_datamodels()) print(sdm.list_all_subjects()) print(sdm.datamodels_subject("dataModel.Weather")) print(sdm.description_attribute(subject, dataModel, attribute)) print(sdm.datatype_attribute(subject, dataModel, attribute)) print(sdm.model_attribute(subject, dataModel, attribute)) print(sdm.units_attribute(subject, dataModel, attribute)) print(sdm.attributes_datamodel(subject, dataModel)) print(sdm.subject_repolink(subject)) print(sdm.datamodel_repolink(dataModel)) print(sdm.print_datamodel(subject, dataModel, ",", ["property", "type", "dataModel", "repoName", "description", "typeNGSI", "modelTags", "format", "units", "model"])) sdm.update_data()
The utils directory at the data models compiles some scripts we use internally.
Now you have available a script for consolidating several @contexts from several subjects.
It is the script called by the main menu options Home->tools -> Subjects’ @context merger
the help of the script
# This file takes several @contexts and merges them creating two files
# context.jsonld with the elements successfully merged
# and conflicts.json that shows those attributes clashing.
# clashing in conflicts file has to be solved manually
# INPUT PARAMETERS (merge_subjects_context.json, outputToFile)
# parameter merge_subjects_context.json
# it is the full path to a file where the path to the @contexts will be located
# See an example of the file below
# If not provided it merges all subjects in the smart data models program
# {
# “dataModel.Weather”: “https://raw.githubusercontent.com/smart-data-models/dataModel.Weather/master/context.jsonld”,
# “dataModel.Battery”: “https://raw.githubusercontent.com/smart-data-models/dataModel.Battery/master/context.jsonld”,
# “dataModel.Building”: “https://raw.githubusercontent.com/smart-data-models/dataModel.Building/master/context.jsonld”,
# “dataModel.Device”: “https://raw.githubusercontent.com/smart-data-models/dataModel.Device/master/context.jsonld”,
# }
# parameter ouputToFile
# when True it outputs two files conflicts.json and context.jsonld
# conflicts.json stores the conflict in the name of attributes (to be solved manually)
# context.jsonld has the attribute name and the Smart Data Models local IRI
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.
At home -> Search -> json export of attributes database of smart data models is the full database of attributes (more than 18000), see the statistics page as an array of JSON objects.
Fields for each attribute
_id: identifier of the item
property: the name of the attribute
dataModel: the data model this attribute is present
repoName: the subject this data model belongs to
description: the description of the attribute
typeNGSI: Whether it is a property, Geoproperty, or relationship
modelTags: inherited from the data model tags
license: link to the license for the data model
schemaVersion: version of the data model
type: data type
model: when available the reference model for the attribute
units: when available the recommended units for the attribute
format: either date, or time, or date-time, or URI, etc the format of the attribute
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
Smart Data Models are openly licensed. It means that nobody is asking you for anything to use them. Indeed it is possible to modify the models and share them.
Anyhow if you are interested in getting some dissemination because you are using them, check the new menu entry (I am already using it!) with a form in which you can be listed as an adopter and get in return dissemination on LinkedIn, Twitter, and in the smart data models blog.
