Abstract: A method and device for reserving an online data storage space involving receiving a storage request containing a set of parameters including at least one parameter corresponding to a quality of service for storage, analyzing the set of parameters, creating, and sending to online data storage units, a reservation request corresponding to the set of parameters, receiving at least one reply to the reservation request corning from the online data storage units, selecting, among the replies received, an online storage unit as a function of all the parameters defined in the storage request, creating a reservation key enabling access to the selected storage space, sending the reservation key and the selected storage space address.

Abstract: The present invention relates to a method for reserving an online data storage space comprising: receiving a storage request containing a set of parameters including at least one parameter corresponding to a quality of service for storage, analyzing said set of parameters, creating, and sending to online data storage units (26), a reservation request corresponding to said set of parameters, receiving at least one reply to the reservation request coming from the online data storage units, selecting, among the replies received, an online storage unit (26) as a function of all the parameters defined in the storage request, creating a reservation key enabling access to the selected storage space, sending said reservation key and the selected storage space address.

Abstract: The resource management method of the present invention includes: storing (90) an instantiable model of a card intended to contain a resource description, said card model, during the instantiation thereof to create a new card, forcing the acquisition of: a card identifier, at least one access path containing an address, and a reference domain for each access path, the reference domain specifying, if the resource is an address, which computer application to execute from among a plurality of applications capable of being specified by the reference domain to contact the person corresponding to said address or to access the information corresponding to said address.

Abstract: The invention relates to a method for operating an ending widget (14) with data retrieved from a starting widget (12), both the starting widget (12) and the ending widget (14) being portable software programs installed and executed through a Markup Language Web based page in order to display, respectively, at least one visual object (26, 28, 30) and at least one visual area (32, 34, 36), characterized in that it comprises the following steps: The step for the starting widget (12) to detect a drag of the visual object (28) and to inform a distant server (38) from such detected drag, The step for the ending widget (14) to detect a drop in the visual area (34) and to inform the distant server (38) from such detected drop, and The step for the distant server (38) to correlate the drag in the starting widget (12) with the drop in the ending widget (14) so as to trigger an action whereby data associated to the visual object (28) performs a function associated with the visual area (34).

Abstract: The invention pertains to a device for managing the availability of digital data (7) accessible over a computer network (3), comprising means for: saving (71) at least one digital data address (www.serv-i.com) whose access availability must be determined, this address being associated with a contact (Agent i) saved in a user's instant messaging application; automatically determining (72) the availability of access to said digital data by means of the computer network (3); sending an availability indicator of said associated contract to the user's instant messaging presence manager (8).
