Sterling: Isolated Storage on Windows Phone 7
Not topic map specific but if you need a backend on for a topic map on Windows Phone 7, this might be of interest.
The launch of Windows Phone 7 provided an estimated 1 million Silverlight developers with the opportunity to become mobile coders practically overnight.
Applications for Windows Phone 7 are written in the same language (C# or Visual Basic) and on a framework that’s nearly identical to the browser version of Silverlight 3, which includes the ability to lay out screens using XAML and edit them with Expression Blend. Developing for the phone provides its own unique challenges, however, including special management required when the user switches applications (called “tombstoning”) combined with limited support for state management.
Sterling is an open source database project based on isolated storage that will help you manage local objects and resources in your Windows Phone 7 application as well as simplify the tombstoning process. The object-oriented database is designed to be lightweight, fast and easy to use, solving problems such as persistence, cache and state management. It’s non-intrusive and works with your existing type definitions without requiring that you alter or map them.
In this article, Windows Phone 7 developers will learn how to leverage the Sterling library to persist and query data locally on the phone with minimal effort, along with a simple strategy for managing state when an application is deactivated during tombstoning.
I use a basic cell phone about once a month. Someone else will have to comment on topic map apps on cell phones. 😉
