Ongoing efforts to generate "Tagged PDF" using pdfTEX
Ross R. Moore · Czech digital mathematics library · 2009
Abstract. Recently PDF has been accepted as a standard for production of electronic documents, as ISO 32000-1:2008, with an acronym of PDF/UA (for “Universal Accessibility”). The second draft ISO 32000-2:2009 is to include specifications for including MathML tagging of mathematical environments and expressions. This talk presents a report on work-in-progress, aimed at: (a) developing the primitive commands for pdfTEX needed to support the production of fully tagged PDF documents; (b) writing appropriate TEX and L ATEX macros to make effective use of the new primitives; (c) authoring changes to internal L ATEX structures to use these macros automatically at appropriate places within the existing code-base for L ATEX. This is work that is being undertaken together with Hàn Thê ´ Thành, author of pdfTEX [2], who has added some new primitive commands to an experimental version of this software tool.
