XMLviesteihin

XMLviesteihin is a term used in Finnish IT contexts to refer to the practice of sending and processing information as XML messages. It describes the exchange of data between software components, services, or organizations in XML-formatted payloads. The approach emphasizes structured, self-describing data that can be interpreted across diverse platforms.

XML messages are organized as hierarchical trees with elements, attributes, namespaces, and optional schemas. This structure supports extensibility and backward compatibility.

Common implementations include SOAP-based web services, XMPP for messaging, ebXML, and various domain-specific standards that encode data in XML. RESTful services may also transport XML payloads, although JSON has become popular in many ecosystems.

Validation is typically performed against XML Schema (XSD) or DTDs; RELAX NG is another option. Namespaces prevent element name collisions and enable versioning of message formats.

Interoperability relies on agreed-upon schemas, encoding rules, and transport protocols. Security concerns are addressed with mechanisms such as XML Signature, XML Encryption, and WS-Security.

While XML messages offer portability, they can be verbose and processor-intensive; robust parsing, streaming methods (SAX, StAX), and schema validation are recommended to improve performance and safety.
