The disclosure relates to a device that is set up for device-internal handling of data in a text format, that has a communication interface set up to interchange binary data, particularly EXI data, and that provides a coder for reciprocally converting the binary data into text format data, wherein the coder is set up to associate resource descriptions with a respective identification number. This association is managed via a resource table, which is managed by the coder and in which a respective resource description in text form has an associated respective identification number. In addition, the device has at least one device-internal database for storing resources and the relationships between the resources. A database access control unit is provided that has access both to the database and to the resource table. Centralization of the resource table advantageously avoids redundant storage of resource descriptions.

The invention relates to a method for establishing an end-to-end communication between two networks, wherein: a message is received from one first network, this message having a first header and an application-data part; data of said first header is coded into a second header within the application data part, with the aid of a first coding scheme, so as to produce a modified application data part; said modified application data part is coded with the aid of a second coding scheme so as to produce a coded message; and this coded message is transmitted to a second network.

The invention relates to a method for integration of semantic data processing in a device, in particular in a field device of automation technology. In this case, a generic description language scheme is used to define a semantic repository as a starting basis. According to the invention, said description language scheme is enriched with content from an ontology for semantic representation of a mode of operation of the device. Classes and/or subclasses of the ontology, together with at least one characteristic assigned to the classes and/or subclasses and taken from the ontology, are converted into a corresponding scheme declaration and said scheme declaration is inserted into the description language scheme. One or more grammars arc then generated from the description language scheme, preferably grammars according to the standardised data format 'Efficient XML Interchange', abbreviated to EXI, which arc integrated in the device. A particular advantage of the invention is substantially compact semantic data processing and data transmission.

A method for providing a web service may include generating an XML-based schema based on a service description of said web service, which generated XML-based schema defines XML-based messages to be interpreted by the respective web service, generating a binary XML processor code for encoding and decoding said XML-based messages based on the generated XML based schema, transforming said service description of said web service into a procedure skeleton code comprising one or more skeleton procedures each becoming an application procedure by implementing an application logic for the respective skeleton procedure, and generating a dispatcher code based on the service description, said dispatcher code configured to interpret a byte stream produced by said binary XML processor code to invoke one of the implemented application procedures. This provides an innovative approach to generate source code for developing XML-based web services for small embedded devices with constraint resources.

Method and apparatus for providing a service implementation

For processing of XML data by use of a finite state automaton, the XML data is based on a predetermined XML schema and the finite state automaton has states and transitions being arranged based on the predetermined XML schema. In the finite state automaton, at least one of the transitions of the finite state automaton, which refers to an element or attribute of the XML schema, has a variable length binary code, the variable length binary code being arranged to code the element or attribute of the XML schema. An improved handling of XML data in several systems or devices of several technical areas is provided, wherein saving of memory resources and processing resources or costs in the systems and devices is enabled.
