<p>The invention deals with sharing user's attributes among service providers wherein a service provider, the Attribute Provider, hosts a user's attribute and registers an attribute offering in a Discovery Service Framework for other service providers, the Attribute Requestors, knowing the Attribute Provider hosting the user's attribute. The problem faced is user's attributes that change very often and require a continuous withdrawal and registration of attribute offerings. The present invention solves this problem by providing a method of registering from the Attribute Provider (AP) an offering registration trigger in the Discovery Service Framework (DSF) intended to request the registration of an attribute offering upon matching triggering conditions, a method of determining trigger conditions to request said registration of an attribute offering when an Attribute Requestor (AR) inquires for the attribute offering, as well as an Attribute Provider (AP) and a Discovery Service Framework (DSF) arranged to this end.</p> |
