This project builds on the success of former projects “Standard XML data dictionaries for chemistry” (project 2002-022-1-024) and “Enhancement of the electronic version of the IUPAC Compendium of Chemical Terminology” (project 2007-016-1-024) in which an electronic version of the IUPAC Compendium of Chemical Terminology (Gold Book) was developed and improved.
The success of and the number of new features that were introduced in the online version of the Gold Book is mainly made possible by using a semantic storage of the information in an XML format. In this project we would like to take this approach a step further and create a second type of output, namely PDF, based solely on the current XML version.
The introduction of PDF output will improve the online Gold Book in several areas. It will give users an output format suitable for high-quality printing and will allow us to completely remove the older PDF version, which is in many cases out of sync with the online content. Both of these functions were a subject of several user inquiries. The experience gained in this work will also allow us to estimate the amount of work necessary to create a printed version of the Gold Book based on the XML data. The main challenge of the conversion to PDF will be to ensure that all content from the online version is preserved, especially in case of complex mathematical formulas.
As a secondary objective, a FAQ document proposed at the CPEP meeting in Glasgow will be created.
The third issue we will address in this project is the existence of many entries in the Gold Book which contain only a link to a related term. These entries were created in the original version solely for the purpose of indexation. Because we developed a system to deal with this issue in a cleaner way for the new Gold Book content, we will apply this method to the older content as well to make the browsing experience more consistent


Dec 2010 – *Release 2.2*. The main new feature of this release is the introduction of PDF version of Gold Book definitions. PDFs are created from the same source as HTML pages, so 100% correspondence of content should be guaranteed. To download the PDFs, use a link at the bottom of each page. Note: this feature is now in a testing phase. Once it is mature enough, we might give it a more prominent place and consider providing more versions of the PDF output.
In this release, the display of automatically added links was changed to distinguish them visually from links added by authors.

Oct 2011 – *Release 2.3*. In this release, entries with related content were merged. This release includes an updated FAQ and an experimental PDF rendering of the whole Gold Book in one file.
