V2 API - situation around Wikipedia & Google Knowledge Graph ids

In V2 of the API it appears you are no longer providing Wikipedia URLs or Google Knowledge Graph (Freebase) MIDs against entities found by the service. These have been an essential feature in the V1 API for us. 

Is this an intentional change, or is this a temporary deficiency that you are intending to fix in V2? 

If it is intentional, would you mind explaining why you have dropped this feature? Are you providing any alternative services for getting this data, or can you point to any other 3rd party services that we could use in its place? Are there plans to discontinue the V1 API at any point and if so, is there any rough sense of when? Thank you.

It appears that these metadata is not yet implemented in V2 (is currently in public preview state), I would suggest visiting the release notes page for the future and previous update of this API.

Alternatively you can file an issue tracker (feature request) to show interest for this feature.

Thank you nceniza. I have created a feature request. I encourage you and others to vote it up here: https://issuetracker.google.com/issues/300511487. 

As mentioned I am hoping this is a temporary problem that will be fixed in future releases.

According to August 28 release it seems they dropped wikipedia_url variable. It would make sense to push users to use Knowledge Graph Search for deeper recognised entity insights.

However the non-existance of mid in response (inside metadata) makes it impossible as there is not reference to entities to search on. We've tried multiple texts - there is just no mid in any of recognized entities.

Having Knowledge Graph IDs is the biggest value of this API as additional insights can be build as KG changes through time. Not having any KG IDs makes this API useless as there is no way to know which KG entry was recognized inside a text.

From Google Knowledge Graph documentation:

Search for entities from MIDs returned by other Google Cloud APIs, such as Cloud Vision API, Cloud Natural Language API and Cloud Video Intelligence API
