Automated README.md for data models

Currently, the README.md at data models level (inside every directory in a Subject) explaining the contents of the data models is automated, and therefore there is no need to be contributed by the contributors. See an example here for the weather forecast.

Thus, the README.md is based on the examples provided, the specification and the model.yaml.

Soon the README.md for the Subject will be also automated.

IUDX joins the steering board of Smart Data Models initiative

IUDX joins the steering board of Smart Data Models initiative. This agreement will allow FIWARE and the IUDX to collaborate on data models suitable for use in smart city applications. This work will be done in conjunction with the ongoing joint activity between TM Forum — an alliance of 850+ global companies working together to break down technology and cultural barriers between digital service providers, technology suppliers, consultancies and systems integrators — and FIWARE.
