Effective in version 10.1, the home page displays the trending search, top 50 assets, and recently viewed assets. Trending search refers to the terms that were searched the most in the catalog in the last week. The top 50 assets refer to the assets with the most number of relationships with other assets in the catalog.
Previously, the Enterprise Information Catalog home page displayed the search field, the number of resources that Live Data Map scanned metadata from, and the total number of assets in the catalog.
