Multiple nested imparrays can be created to match multiple nested arrays in XML as XML does not have the need to declare the length of an array. The D3L syntax enables you to create multiple nested imparrays for outbound translations ( app-to-native or hub-to-spoke). Simlarly, for outbound messages, the OracleAS Integration InterConnect message payload property value will define the value of the corresponding protocol header.įor example, if using OracleAS Integration InterConnect Adapter for FTP, the file structure would be: In other words, when a D3L containing a structure with one, or more, property member(s) is imported in iStudio, it will create a String OAI attribute with the name specified in the property name attribute.Īt runtime, this OAI attribute will be populated with the value of a transport protocol header, inbound–to-hub, which name matches the name attribute of the property member. The semantics of this new structure element is to link data in a transport protocol header with the message payload. The modified D3L Data Type Definition (DTD) for this new structure element is: Note:There is no type definition associated with this structure element. D3L is not suitable for the following:ĭescriptions of arbitrarily structured data like regular XMLĬonditional data structures, which require token look-aheads to parse Use D3L only when the number of fields in the underlying native format message is fixed and known. D3L enables you to describe the record layout of binary, string, structured, and sequence data. The D3L descriptions must comply with a syntax defined by the D3L document type definition (DTD).
D3L provides:Īn XML-based message description language that describes the contents of native format messagesĪ translation engine that uses the instructions defined in the D3L file to translate the native format message contents to and from an application view This structured format can then be translated into an application view, transformed into a common view, and understood by other applications.ĭ3L provides both a predefined, structured set of rules and translation capabilities for native format messages. For these native formats to be successfully translated into a format understood by other applications, the messages content must follow a predefined, structured set of rules. These applications use native formats, such as structured records of bytes and characters. Some applications do not use XML as native message payload format.
