I am currently accepting work on standards editing as well as topic map and semantic integration consulting/projects.
For an example of my standards editing work, see the OpenDocument Format (ODF) standard at OASIS. (I am also the ISO project editor for ISO/IEC 26300, that is ODF at ISO.)
OpenDocument Format is one of the formats supported by current versions of MS Office, OpenOffice, Lotus, KOffice, LibreOffice and other fine word processing software.
For my topic maps work/interests, you can consult many of the entries of this blog and/or ISO/IEC 13250, part 5, the Topic Maps Reference Model.
