Abstract: The invention present disclosure relates to a method and device for coding a structured document, particularly such as a XML-based document, wherein a plurality of codes are generated by one or more schemas or namespaces, wherein independent codes are assigned for a schema and/or a namespace separately from other schemas and namespaces, for the elements defined or declared in the schemas or namespaces or in groups of schemas or namespaces.

Abstract: In one embodiment of the present invention, the synchronisation of data segments is particularly necessary for the use of small screens. A method and a device are disclosed for synchronising content-dependent first data segments of a first data file and content-dependent second data segments of a second data file, the first and second data segments being respectively output in sequence according to their chronological order in such a way that based on a predeterminable assignment rule for the first and second data segments, each second data segment is output together with a corresponding first data segment.

Abstract: The present invention relates to a method for coding positions of data elements in a data structure. According to the method, position codes are associated with the data elements in a pre-determined sequence, the position codes being selected in such a way that, if the lengths of the position codes are unlimited, many other position codes can be arbitrarily allocated between the positions of two data elements in order to code positions of other data elements. The present invention also relates to a method for coding positions of data elements in a data structure, whereby position codes are associated with the data elements in a predetermined sequence, the position codes being selected in such a way that other position codes can be allocated between the positions of two adjacent data elements in order to code positions of other data elements, at least one other position code being longer than the longest position codes of the two adjacent data elements.

Abstract: A method serves to encode textual paths for indexing and querying structured, for example, XML-based documents and serves to execute and improved filtering of binarily represented XML documents. A development of the method results in all indices being identical even in the event that a polymorphism is inserted therein. When storing these textual paths for indexing or querying, only one smaller volume of data has to be stored or transmitted. A comparison of this data can also subsequently ensure more rapidly during a query since the volume of data to be compared is smaller.

Abstract: A method is disclosed for creating a bit stream from an indexing tree including a plurality of hierarchical levels, to each of which one or several index nodes are assigned. The index nodes contain index data which is sorted in the indexing tree according to one or several given criteria. Index data of the index nodes is inserted into the bit stream, and the information concerning the position within the bit stream, where the index data of one or several index nodes of the hierarchical level located below the hierarchical level of the respective node is situated, is inserted into the bit stream for an index node.

Abstract: A method is provided wherein two different schema branch codes are used, whereby one of the two is utilized far more frequently and, as a consequence, effects a compression. The schema branch code and position code are combined, and the bit length for the schema branch code is transmitted therewith. This results in simplifying the search function in such a manner that the first part, alone, specifies the type of the referenced element and that an improvement in the extensibility is achieved based on a schema version number to be transmitted and on firmly prescribed extension strategies that are also familiar to the decoder.

Abstract: A method is for encoding a structured document, particularly an XML document, during which the contents of the document are converted into a binary representation. This binary representation is divided into encoding units, which form an encoded data flow and can be read out from the encoded data flow. The encoded data flow contains configuration data, with which configuration information concerning the division of the binary representation into encoding units can be read out before the reading out of one of more encoding units.

Abstract: The invention present disclosure relates to a method and device for coding a structured document, particularly such as a XML-based document, wherein a plurality of codes are generated by one or more schemas or namespaces, wherein independent codes are assigned for a schema and/or a namespace separately from other schemas and namespaces, for the elements defined or declared in the schemas or namespaces or in groups of schemas or namespaces.

Abstract: The invention relates to a method for querying a database with database contents that have a database structure. The query is made in a query structure, which differs from the database structure in that the query structure and the database structure reference a standard structure, and the reference logic is at least partially transmitted together with the query and/or is at least partially present in the database.

Abstract: A method for transmitting a vector having at least two vector components, each of the vector components described in a frequency. Each vector is represented as a bit number with a predetermined number of bit levels. The bit numbers are encoded according to a priority of the bit levels and the encoded bit numbers are transmitted.
