Give Credits to original Authors as per the Licenses stated on the original repositories

This project has copied a bunch of Data Models from the original https://github.com/FIWARE/data-models and its successor https://github.com/smart-data-models. Credits MUST be given to the original authors by honouring the licenses stated on the source repositories.

I think it is not a matter of referencing FIWARE Data Models as a resource, like the referenced commit made, but for each data model that has been repurposed or re-encoded here it has to be clearly stated what is its original source and a pointer to that source

I've taken the approach to add a reference to the original data model specification in the 'comment' attribute in the interface model. E.g. in Ontology\PointOfInterest\PointOfInterest.json

{
    "@id": "dtmi:digitaltwins:ngsi_ld:city:PointOfInterest;1",
    "@type": "Interface",
    "displayName": "Point of Interest",
    "description": "Global description: This entity contains a harmonised geographic description of a Point of Interest",
    "comment": "Original source: https://github.com/smart-data-models/dataModel.PointOfInterest/blob/master/PointOfInterest/doc/spec.md",
    "extends": "dtmi:digitaltwins:ngsi_ld:city:NGSILDBaseModel;1",
    "contents": [

Is this OK and enough?
