Abstract: The present invention relates to a method and a system for managing access to a resource, copies of which are hosted in apparatuses of one or more networks. The method comprises obtaining a list comprising a plurality of references pointing to the plurality of copies of the resource; for each of said references, determining at least one accessibility rating representing the accessibility of the corresponding copy for the given user device, and, based on the at least one accessibility rating, deciding between keeping the corresponding reference in the list or deleting it therefrom, to obtain an updated list; and selecting a reference from the updated list for the given user device to access the resource.

Abstract: Generating reference structural patterns representing hierarchized data, by extracting primary structural patterns. Each primary structural pattern represents a set of pieces of structural information. The degree of use of extracted primary structural patterns is determined based on of the number of hierarchized pieces of data able to be represented by the primary structural patterns. Primary structural patterns are grouped based on the degree of use and a distance between primary structural patterns. One reference structural pattern per group is determined, the reference structural pattern representing the primary structural patterns of the associated group.

In response to the comparison of their coding efficiency, the second or the fourth sequence is coded.

Abstract: This invention relates to a method of encoding a path (1) in layered form so as to allow partial decoding and progressive rendering while decoding. The path (1) is made of an original sequence (20, 23) of original draw commands, each corresponding to an original portion of a drawing. The method of encoding comprises the following steps: transforming (E120, E230, E430, E440, E450) at least one original draw command into an approximating draw command according to a geometrical approximation of the corresponding original portion of a drawing, to obtain a reduced sequence (25); encoding (E130, E250) said reduced sequence (25) into an encoded reduced sequence; and encoding (E150, E260) a reconstruction information set (26) representing the difference between the reduced sequence (25) and the original sequence (20, 23). The invention is particularly suitable for graphics description languages, such as SVG.

The method includes generating at least one unified model representative of the structure of an element type on the basis of at least one structured configuration document, said unified model including statistical information on transitions between items made in the occurrences of said element type within the configuration documents, and optimizing said unified model, using the statistical information on transitions, by deletion of at least one transition of the unified model and/or grouping together of at least two transitions within the unified model. Thus, the transition information makes it possible to configure the processor with a number of productions that is limited and adapted for the coding or the decoding of the structured documents.
