Overview
• A motivating example: A Watch Product Line
• possible feature diagram
• possible UML 2 diagram (with profiled additions)
• associated metamodel / conceptual model
• Motivation for System Families / Product Lines
• the Families project based on ESAPS and CAFE
• not only language – also organization and process (BAPO)
• Why standardization?
• Why we want to get OMG involved
• The relationship with MDA
• The possible OMG approaches
• RFI (Request for Information)
• RFP (Request for Proposal)

What now?
• RFI (Request For Information)
• An RFI is a Request for Information. It surveys the computing
industry, collecting information that OMG members use to
form and guide new standards-setting efforts.
• Do we need this?
• RFP (Request For Proposals)
• A Profile of UML
• A Process within the MDA domain
