This already exists in a limited form but must be expanded to include all aspects of FAI data based on their [entity id].
In some cases an entity will have one data item, eg a person can have only one name.
In other cases an entity will have many items, a committee has many members, a championship has many entries (= person entities).
This is a simple database storage system, but data items may refer to external content (eg files in a file system, urls Etc)
Data is inserted, updated, deleted and retrieved via [web based interfaces] or the [API]
