XML schemas - Foreword XML schemas define rules for structure and content of ISVS Common Interface XML documents. In other words, they define syntax (format) and semantics (meaning) of transferred information Every XML schema identifies class of XML documents conforming to this schema XML schemas are result of agreement between the communication parties

Data types vs. data elements Data element : –Common definition : In the concrete context, the data element is a indivisible data unit –By EDIFACT : data unit, described by identification, description and format Data element description is syntax-neutral. Data type : –Common definition : Category of classification of letters, digits and/or symbols, based on operations available for this data type (ČSN ) –XML data type : XML structures class declaration Data type description has XML syntax.

Web services and XML schemas Web Service can be described as set of network co-operating programs, where no explicit human involvement during transactions is required. Web services communicate using messages Commonly, the message is XML document containing required data. XML schemas define syntax and semantics of XML messages.

Architecture of ISVS XML schemas Architecture of ISVS XML schemas uses ebXML „Draft Core Components Specification“ model. The set of context-neutral, basic data types constitutes Core Component Types schema. Core Component Types schema is reused by reference schemas, data dictionaries schemas and/or message schemas.

Architecture of ISVS XML schemas

ISVS XML schemas Developer‘s Guide ISVS XML schemas Developer‘s Guide is a contribution of MI to schemas development process The first public draft will be released during April 2003 „Guide“ is a compilation of similar documents from other countries (UK GovTalk, US Federal XML Developer‘s Guide, UBL, ASC X12) It contains set of recommendations for development of ISVS XML schemas and replenishes the ISVS reference interface standards.

Organization of ISVS XML schemas development The core units are the „Working Groups“ Working groups use the central methodology, originating from Central ISVS Working Group At the department level, there will arise department Working Groups At the lowest level, the Service Working Groups create and maintain the entire schemas of concrete Web Service.
