Feed Subscription Management
An increasing number of data sources and services are made available on the Web, and in many cases these information sources are or easily could be made available as feeds. However, the more data sources and services are exposed through feed-based services, the more it becomes necessary to manage and be able to share those services, so that users and uses of those services can build on the foundation of an open and decentralized architecture. In this paper we present the Feed Subscription Management (FSM) architecture, which is a model for managing feed subscriptions and supports structured feed subscriptions. Based on FSM, it is easy to build services that manage feed-based services so that those feed-based services can easily create, change and delete feed subscriptions, and that it is easily possible to share feed subscriptions across users and/or devices. Our main reason for focusing on feeds is that we see feeds as a good foundation for an ecosystem of RESTful services, and thus our architectural approach revolves around the idea of modeling services as interactions with feeds.
