Linking of entities

Some entities in Operations Center can have links with other entities. For example, tags and resources can be assigned to work items.

Since OC is based on event sourcing, there is a corresponding event to link entities.

The linking event is only saved to one blockchain even if it is bi-directional. Otherwise, transactional consistency cannot be archived. The linking event is saved to the chain where the action is being performed.
