What is "ds-xml"

The Design Extensible Markup Language (DS-XML) was initiated in 2005 at the Office for Harmonization in the Internal Market as an open standard based on TM-XML for the exchange of information in XML on Design information.

Its latest version is the DS-XML version 1.1 published in October 2009 covering the information for eFiling, publication and dissemination of Design Register's data and the version 1.0 has been adopted as WIPO International Standard 86 aka ST.86 in February 2009.
