WBXML library

W3C ready

The WAP Binary XML (WBXML) specification defines a compact binary representation of the Extensible Markup Language (XML). The binary XML content format has been designed to allow for compact transmission of XML data over limited-bandwidth communication channels without loss of functionality or semantic information. WBXML provides improved compression of SIP payloads over what can be achieved with generic SigComp compression. Combined with SigComp compression, the WBXML library is suitable for IMS presence and messaging.

Improved WBXML compression can be achieved using standardized dictionaries. One basic dictionary is the Wireless Markup Language (WML) specified by the Open Mobile Alliance (formerly WAP Forum).

The WBXML library supports the following features:

supports WBXML version 1.3 (aka WAP 2.0)
XML to WBXML compression with specified dictionary
WBXML to XML decompression
WBXML decoding with SAX-like events

Supported dictionaries include: WML 1.0-1.3, WTA 1.2, CHANNEL 1.2, SI 1.0, SL 1.0, CO 1.0, EMN 1.0, PROV 1.0, and DRMREL 1.0.

The WBXML library is available for Microsoft Windows, Mac OS X, NetBSD, Linux and Symbian. Support packages are available and our engineers can provide assistance with any customizations that individual customers may require.
