Does LinkedIn read the Open Graph meta tags?

LinkedIn reads the Open Graph meta tags for the title, description, url, and image.

The first time that LinkedIn’s crawler visits a webpage, the meta tags it reads will be cached for approximately 7 days. If you later update the webpage’s description, select a new image, fix a typo in the title, etc., you will not see that change reflected on LinkedIn for past or future shares of the same URL, until LinkedIn’s cache has expired (approximately every 7 days).
