On June 19-21, 2006, the committee held its fourth face-to-face meeting in Sapporo, Japan. The meeting was hosted by Toshiba and attended by eighteen participants. The technical agenda included new material on SpreadsheetML, PresentationML, DrawingML, compound documents, and the Open Packaging Conventions. The committee reviewed issues and modifications to WordProcessingML as proposed by the committee, and finished resolving substantive issues regarding conformance and interoperability. Highlights of the meeting included presentations by Statoil, BP, and Essilor of methods for visualizing and analyzing the schema interdependencies defining the file format, and demonstrations of Java prototype tools by Toshiba to transform Office Open XML to HTML for viewing in any browser. Ecma has requested liaison with ISO/IEC JTC1 SC34 in order to help prepare a possible Open XML submission to ISO/IEC, and SC34 has appointed a liaison officer. The TC45 committee's next face-to-face meeting will be hosted in August by Microsoft in Redmond, Washington.
