Abstract: An Internet of Things Controller, and related tools. The tools address application development and deployment. An Application Meta-Data Editor permits a developer to specify meta-data, that guides the structure of actual data, that can be passed to the application, when invoked as a particular execution (or task) for a particular end-user. Once an application is developed, and has undergone a test deployment, the developer can upload the application to an online Application Store, from which the application can be downloaded and deployed by others. A Data Editor permits an end-user to create his/her own data, in accordance with the developer's meta-data, that adapts the execution to his/her particular needs. While permitting adaptation, the Data Editor ensures that the data created follows the overall pattern of the meta-data, as provided by the developer. Facilities for internationalization of a deployed application's documentation, on a crowd-sourced basis, are also provided.
