Contributions are assembled to Assets by the community – i.e. multiple Contributions, contributed by different CommunityMembers may be assembled together to one consumable asset.<br/>Examples for assets are open source software; in that case the source code might be contributions of various CommunityMembers. Another example is Facebook; the original post and the comments are contributions, provided by different CommunityMembers, a whole discussion thread is an asset that can be consumed by other CommunityMembers.<br/>Consuming an Asset from a Community, again, is a BusinessInteraction, which items are associated to Products, which is the consumed asset. That product might be instantiated from a ProductOffering and associated to a ProductPrice, so it possible to model Assets with a price, too.<br/>
