Google may soon start a new service Google Base according to Ars technica

Google Base is Google's database into which you can add all types of content. We'll host your content and make it searchable online for free.

Examples of items you can find in Google Base:

• Description of your party planning service
• Articles on current events from your website
• Listing of your used car for sale
• Database of protein structures

You can describe any item you post with attributes, which will help people find it when they search Google Base. In fact, based on the relevance of your items, they may also be included in the main Google search index and other Google products like Froogle and Google Local.
