Mashup Markup Language (MML) Components

Mashup Markup Language (MML) Components

MML will contain a high level description of a mashup. The current thinking is that MML will contain the following components (each component is denoted by an XML element)

• Services – a list of services the mashup will use (these are publicly available webservices)
• Rules –  A set of rules for filtering, selecting data from services. These include how to aggregate data, how to correlate data from one service to another, etc.
• Transformations – Provides a description of  how the aggregated/correlated data is transformed before it is sent to a client.
• State – State management related information
• Orchestration or Workflow – If there are multiple services the output of one service may form the input of another service.
