An application programming interface (API) layer is implemented on a computing device. The API layer allows a local application(s) executing on the computing device to access web data in a data store layer, and further allows a remote application(s) that is executing on some other computing device to access the web data in the data store layer. Additionally, this web data can include web pages, some of which may include structured data and some of which may not include structured data. A web browser is permitted to access the web data store via the object model, and generate a user interface based at least in part on these web pages.
