Standard: Portable Game Notation Specification and Implementation Guide
This text was instrumental in the fast spreading of chess games on the Internet. For the first time, developers of chess software had a reliable, precise and accessible definition of an open format their programs could read and write.
The text is available in its original (ASCII) format on the Internet since it was written in 1994. It was tagged as an XML file, using the Docbook XML DTD, by Andreas Saremba in February 2000. The intention was to make the text easier to read and to quote, and to honour its importance for the development of chess.
The text was copied as verbatim as possible; no attempt was made to verify the validity of the links and addresses. As a consequence, links have not been tagged but remain normal text.
The XML file was then transformed to HTML and (via RTF and Winword 97) to Adobe's PDF format; the transformation from XML to RTF was done with Norman Walsh's DSSSL stylesheets without manual editing.
