Info Garden and the Walled Garden
Info Garden is a service of the Consumer Horticulture Program at Purdue University and provides gardening information to help gardeners successfully grow their favorite plants. Although prepared primarily with Indiana and Midwestern gardeners in mind, much of the information is applicable to gardeners around the world.
In the realm of network-based content, a walled garden is an environment that controls user access to network-based information and services. The term "walled garden" has been given other names such as "walled prison" and "walled desert." A walled garden does not prevent users from navigating outside the walls of the environment, but it does restrict their navigation to a specific selection of material and may prevent them from being able to access certain types of material entirely.
Apple's App Store is a well-known example of a walled garden because it does not allow the download of applications that do not meet Apple's stringent application development requirements. Collaboration apps such as Slack and Microsoft Teams also use a walled garden approach by only allowing communication between users who are members of the same team in the collaboration app.
