Work has been completed in Study Group 17 on the development of Recommendations that could see web services (web-based application to application communication) being adopted in areas such as mobile telephony.

Web services are a standard way for all types of software to interoperate across programming languages, platforms and operating systems. They give a structured way to format data - using XML - such that it is easier for different types of programs to communicate. An example of an area that might benefit from increased efficiency in this area would be the integration of enterprise applications in a large supply chain.

The issue that the new Recommendations address is that structured data in XML contains a lot of redundant information which slows processing down. And, because of this the adoption of web services in certain areas such as mobile telephony where constraints include bandwidth and the ability of mobile devices to process data, have been limited.

The new Recs (X.892 and X.891) solve the problem using ITU notation language ASN.1 to specify alternative and more efficient codings of structured data, both in terms of size and processing speed.
