A binary-coded structure document, (e.g., in an EXI format which is based on a structure document designed in a text-based description language, such as XML), is provided with a binary-coded index document, which is based on a structural part of the structure document. A storage representation of the binary-coded index document is stored in a working storage unit of the device, and the binary-coded structure document is stored in a background storage unit assigned to the device. A processing operation or a request by at least one processing process is carried out by accessing the storage representation of the binary-coded index document via an object interface, and in certain examples, fragments of the binary-coded structure document are loaded into the working storage unit by the object interface. By carrying out processing operations on the binary-coded index document, faster request operations are facilitated in that specific requests may already be processed using the index document BCI without the involvement of the binary-coded structure document.

Device and method for processing a binary-coded structure document

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.

Device with communication interface and method for controlling database access

A method is provided for converting a binary data stream, (e.g., an EXI data stream). In an initialization phase of the method, a plurality of grammars, previously produced from at least one description language scheme, are read from a memory area and combined to form a combined grammar and wherein the combined grammar is supplied to a runtime environment for the purpose of converting the binary data stream. The method firstly permits substantially accelerated production of the desired grammar in comparison with a grammar produced as required from individual schemes, and secondly the memory space requirement may be kept down, because there is no need to keep a combinational variety of grammars available.

Method for converting a binary data stream

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.

Method for integration of semantic data processing

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

In a method and an apparatus () for searching in a memory-efficient manner for at least one query data element in a graph (A), only as many data elements are read into a memory as are required for their subsequent processing. Increased memory efficiency is ensured as a result of this. The proposed apparatus is particularly suitable for use in terminals having very limited memory, in particular in mobile terminals.

Method and apparatus for searching in a memory-efficient manner for at least one query data element

A method is disclosed for coding a structured document, wherein a plurality of codes is generated by use of one or more schemata and/or name spaces. For a schema and/or a name space and/or for a group of schemata and/or name spaces independent codes for the elements defined or declared in the schemata and/or in the groups of schemata and/or name spaces are allocated. For every schema and/or name space an allocation to additional schemata and/or name spaces is carried out. A corresponding coding method, a coding device, a decoding device and a coding/decoding device are also disclosed.
