There are four primary goals of this project
1) Create a stable, modern version of the current Gold Book website (https://goldbook.iupac.org/)
2) Create a downloadable vocabulary of Gold Book terms
3) Create a simple website to administer updates to Gold Book terms
4) Create a simple Application Programming Interface (API) to access the Gold Book terms
These activities are intended to stabilize and prepare the Gold Book website for future development via subsequent projects. In addition, the use of the existing Digital Object Identifiers (DOIs) assigned to the Gold Book terms will be leveraged to provide machine readability of the terms.
The IUPAC Gold Book website (https://goldbook.iupac.org) is an important product of IUPAC. It is a visible face of a significant investment that the members of the IUPAC Divisions have made over the years to formal definitions many important chemical terms. It is also a valuable resource that needs to be tapped for representation of chemical concepts in the digital realm and this project is a significant step toward that goal.
Digital representation of the IUPAC Compendium of Chemical Terminology – the “Gold Book” – started in 2002 in project 2002-022-1-024, and was continued by project 2007-016-1-024. The most recent project (2013-052-1-024) was focusing on building a management system for the terms in the Gold Book. A database and web portal were designed that could be used to develop a dynamic website. However, with the recent move of the main iupac.org website to WordPress (different from the platform used for old.iupac.org), that project is on hold to first address issues of stability and integration into the new website.
Currently, the Gold Book is at version 2.3.3 (as of February 2014) and is in need of significant technical maintenance. In the last few months, pages from the website have ‘disappeared’ (the files have become empty) for no apparent reason. As an emergency measure the website was moved to a new hosting platform and over ~8,000 files were recovered from the Internet Archive. The new hosting platform can be administered through a web interface and this will allow maintenance of the existing pages while the activities of this project are undertaken.
The previous project raised a number of issues relative to the data currently used in the Gold Book website. The complexity of the XML encoding of the website made it difficult to ‘pull apart’ features of the site from the text. Reliance on python scripts to generate maps (from the XML) and ‘Goldify’ the pages further complicated maintenance. These issues, in addition to the stability of the current website and the ongoing need to update terms in the Gold Book demand a better solution moving forward. Note: No modifications to the current terms will be made during this website redevelopment project unless requested by IUPAC Division representatives. Pending the creation of a new, stable Gold Book website, IUPAC Divisions will be requested to update/add entries as they deem necessary.
There are four primary goals of this project
1) Create a stable, modern version of the current Gold Book website. The activities are as follows:
a) Conversion of the current XML-based webpages to dynamically generated webpages. The XML webpages will be deconstructed and imported into a MySQL database. Subsequently, a web scripting framework (CakePHP) will be used to re-create identical versions of the Gold Book pages reusing the existing image files, MathML files and formatting. This will be developed and deployed at a separate URL than that of the current Gold Book so that the Task Group members can test and evaluate the pages prior to replacement of the existing pages. Once the new version of the site is deemed acceptable for community access it will be made available as a beta version of the current site for three months. This will allow us to gather user feedback on any additional changes that are needed. After that period the new site will replace the existing one.
b) Website functionality (search, etc.) currently implemented in python will be converted to CakePHP.
c) Gold Book pages will be augmented with Google Analytics code to allow monitoring of the usage of the Gold Book terms. This will generate usage statistics, demographics, and referring page information (useful for identification of users).
2) Create a downloadable vocabulary of Gold Book terms – the Gold Book terms and DOI’s will be made available in different formats (CSV, XML, JSON) to make it easier for developers of science-related sites to use the terms on the Gold Book website. Documentation of the vocabularies and guidelines for appropriate usage will also be made available.
3) Create a simple website to administer updates to Gold Book terms – once the webpage content (Gold Book terms and related information) is in the MySQL database a simple administrative interface will be created to update the text of the terms. This will be tested by Dr. Chalk based on updates submitted from IUPAC Division representatives.
4) Create a simple Application Programming Interface (API) to access the Gold Book terms – as a forward thinking activity, a small API will be developed in order to demonstrate the potential for the website to provide information about the Gold Book terms programmatically via a JSON encoded representation of the Gold Book terms. This proof-of-concept will inform use cases for future project proposals.
Project code will be backed up (ongoing) to a GitHub repository, which will also allow versioning and a history of the code development. This, plus documentation within the code will make it easier to maintain and transition to future developers.
Additionally, a log of time spent on the project will be captured and used to develop and estimate of ongoing maintenance needs of the Gold Book website.
This project is complementary to project 2013-052-1-024
May 2017 update – An interim HTML5 revision to the existing site (see https://goldbook.iupac.org) was established in March, allowing access to the current version of the Gold Book while the activities of this project are undertaken. Tracking of access to the website was also added using Google Analytics and reports for April 2017 (https://bit.ly/2qhVW0T) and May 2017 (https://bit.ly/2qigTbU) are available. Currently, the top three accessed terms are “standard solution,” “empirical formula,” and “Stern-Volmer kinetic relationships.”
Under the leadership of Dr. Stuart Chalk, Associate Professor Chemistry at the University of North Florida (USA), this effort will create a stable, modern version of the current Gold Book website; a downloadable vocabulary of Gold Book terms; a simple website to administer updates to Gold Book terms; and a simple Application Programming Interface (API) to access the Gold Book terms.
A demonstration of the beta version of the new Gold Book website and hands-on presentations will be offered at the 2017 IUPAC World Chemistry Congress in São Paulo, Brazil this coming July. The beta version will be accessible to gather user feedback on any additional changes that are needed. After a review period the newly-developed site will replace the interim one and CPCDS will continue to identify enhancements that will facilitate the broadest possible use of IUPAC terminology.
Jan 2018 update – a free webinar titled Repurposing the IUPAC Gold Book hosted by ACS Publications & ACS CINF, will be held Wednesday, January 24, 2:00pm EST.
June 2019 update – A new version of the website <https://goldbook.iupac.org> was built to using modern technology (dynamic pages from a SQL database), provides content for both humans and machines (via the API), and anticipates Web 3.0 (the semantic web). The project was developed with ongoing maintenance of this important digital IUPAC asset in mind, with code stored on GitHub and the database perpetually backed up in multiple locations. While the content of the entries in the Gold Book is the same as previous editions, the site will continue to evolve as requests from users and new technologies dictate. Direct questions and comments to Stuart Chalk (Task Group Chair).
April 2020 update – A redesign has been completed and will be implemented in the next update/release of the Gold book. Follow-up projects have been initiated, including project 2019-032-1-024 ‘DEVELOPMENT OF AN IUPAC RECOMMENDED TERM MANAGEMENT SYSTEM FOR EXPANSION OF THE COVERAGE OF THE IUPAC COMPENDIUM ON CHEMICAL TERMINOLOGY’, and contribution by various Divisions, e.g. project 2019-043-2-400 ‘GOLD BOOK UPDATE FOR POLYMERS’.
