During the very long and drawn out keynote here at Google I/O today, there were many speakers and many topics addressed, including a number of new announcements from Google. Among these was the announcement of the Chrome Web Store, dubbed an open marketplace for web apps that helps people find the best web applications across the internet and allows developers to reach new users. The announcement was only a preview.

The Chrome Web Store emphasizes installable web apps. The company explains:

An installable web app is a normal web site with a bit of extra metadata. You build and deploy this app exactly as you would build and deploy any web app, using any server-side or client-side technologies you like. The only thing that is different about an installable web app is how the app is packaged.

Google Chrome and the Chrome Web Store will support installable web apps. For now, to load installable web apps you need a Windows Dev channel release of Google Chrome with a special command-line flag, as described in the developer’s guide.

Google says the store will be available later this year.
