Welcome to the City Data Model Collaboration Wiki!

We have created this website to enable stakeholders and related standards groups to:

• Review the contents of the City Data Model.
• Propose new classes or properties
• Comment on existing classes
• Comment on proposed classes
• Suggest changes and additions

How it works

Anyone with an account can comment on proposed or existing terms, and even propose their own.

Propose a new class:

How it works

Anyone can propose a new term. Once a term has been proposed, it becomes open for the specification of definitions from the community. The administrators will review all proposed definitions and identify the maximal common definition for the term. The term and resulting set of definitions will then be published as approved in the City Data Model.

Here's a high-level overview of the process that we follow when a new term is proposed for the City Data Model:

<uml> @startuml title Proposing a New Term for the CDM

start

create proposal;

suggest appropriate ontology;

   if (new ontology?) then (yes)
       :Propose New Ontology;
   else(no)
   endif;

specify description;

specify definition (UML or DL);

specify use case(s);

publish for review;

users review proposal;

if (requirement is met by an existing class or property?) then (yes)

   :indicate redundancy in comments;
   if (community in agreement?) then (yes)
       :close proposal;
       stop
   else(no)
       while (undecided) is (yes)
           :discuss;
           :editorial review;
       endwhile(no);
   endif;
   else(no)
   endif;
       :users propose revisions/additions to definition (properties, constraints), motivating scenarios;
       
           if (owner revise?) then (yes)
               :comment resolved;
           else(no)
               :comment left unresolved;
           endif;
   
       :editorial review;
       :editorial comments to author;
       :author revisions;
       :final review;
       :publication of final version (change protected);
