-- Access policy: determines whether a particular consumer is offered an asset or not. For example, we may want to restrict certain assets such that only selected consumers from a list of slescted partners can access the asset. This can be done using a unique identifier such as the Business Partner Nukber (BPN). Other dta space participants than those whose BPN is listed in the access policy wouldn't even have the assets in their catalog.
-- Contract policy: determines the conditions for initiating a contract negotiation for a particular asset. Note that does not automatically guarantee the successful creation of a contract, it merely expresses the eligibility to start the negotiation.

-Now that the asset is created, an access policy must be created to define who shall be able to see the asset within the catalog. This time Bob does not want Alice to see the asset. So he defines a policy not allowing Alice to see the asset in her catalog.
+Now that the asset has been created, Bob creates an access policy that defines who can see and therefore access the asset in his catalog. To specify this access, Bob uses the Business Partner Number (BPN). The BPN is a unique identifier for participants of a data space.
