The Royal Society of Chemistry has provided access to data associated with millions of chemical compounds via our ChemSpider database for over 5 years. During this period the richness and complexity of the data has continued to expand dramatically and the original vision for providing an integrated hub for structure-centric data has been delivered across the world to hundreds of thousands of users. With an intention of expanding the reach to cover more diverse aspects of chemistry-related data including compounds, reactions and analytical data, to name just a few data-types, we are in the process of implementing a new architecture to build a Chemistry Data Repository. The data repository will manage the challenges of associated metadata, the various levels of required security (private, shared and public) and exposing the data as appropriate using semantic web technologies. Ultimately this platform will become the host for all chemicals, reactions and analytical data contained within RSC publications and specifically supplementary information. This presentation will report on how our efforts to manage chemistry related data has impacted chemists and projects across the world and will review specifically our contributions to projects involving natural products for collaborators in Brazil and China, for the Open Source Drug Discovery project in India, and our collaborations with scientists in Russia.

  • 1. Dealing with the complex challenge of managing diverse chemistry data online Antony Williams, Valery Tkachenko, Alexey Pshenichnov and Ken Karapetyan ACS San Francisco August 2014
  • 2. CAS Counter http://www.cas.org/content/counter
  • 3. About Me…as a Chemist • I’ve performed a few dozen chemical syntheses • I’ve run thousands of analytical spectra • I’ve generated thousands of NMR assignments • I’ve probably published <5% of all work • Most of it has been lost • But things can be different today…. • But it still needs to be associated with me…
  • 4. • If we imagine that permission exists… (i.e. forget IP, chemical and pharma companies etc…think students…) – How many syntheses are performed – How many spectra are run – How many properties are measured – How many compounds are made – How many, how much, how big??..... – Let’s go manage it all!! Think about chemistry a mo’
  • 5. Consider a shift to Openness
  • 6. Times have changed… Open Access funder mandates…
  • 7. Publishers are responding
  • 8. The world of Open Data is here
  • 9. Open Data are everywhere • Is Openness and Social Sharing changing the world? • The cultural experiments in Open Data and exchange are almost daily • Mobile platforms enhance participation • And then what of Chemistry Data???
  • 10. An Experiment - ChemSpider • ChemSpider allowed the community to participate in linking the internet of chemistry & crowdsourcing of data • Successful experiment in terms of building a central hub for integrated web search • More people are “users” than “contributors” • Yet basic feedback and game-play helps
  • 11. An Experiment - CSSP
  • 12. An EPSRC Call “…the identification of the need for a UK national service for the provision of a searchable, electronic chemical database for the UK academic research community.”
  • 13. National Chemical Database Service
  • 14. • Manage “all” of the chemistry data associated with chemical substances – PUBLISHED and UNPUBLISHED • Based on user selected licensing the data to be downloadable, reusable, interactive • Build a platform that enables the scientist • Data storage, validation, standardization and curation • Collaborative data sharing • Provide data platform that can enable and enhance publishing of scientific papers We set a vision…
  • 15. Data Repository • Registration of chemical compounds • Deposition of chemical syntheses • Addition of analytical data • Integration to electronic notebooks • Rewards and recognition for data sharing • Document processing • Hosting of data as private, embargoed or public
  • 16. Development of Data Repository • Data repository should not just be a data dump – should not be a “big disk” • Searchable, integrated, segregated repository of data types • Data access including private, shared embargoed and public • Delivery of derived models from data

  • 32. Depositions User Interface
  • 33. The challenges of analytical data • Vendors produce complex proprietary data formats and standard formats are required (JCAMP, NetCDF, AniML) • ChemSpider already hosts thousands of JCAMP spectra • Support of “assigned spectra” in place • Data validation approaches understood • There are a myriad of analytical data types…

  • 63. AltMetrics Feeds • For our data repository ensure contribution of data will feed out to the AltMetrics platforms • Every data point, every data download, use and reuse will be associated with the scientist • Data will be DOI’ed (presently under review) • Services provided will allow for AltMetrics use
  • 64. What do we have in place? • We are testing an early form of the data repository on our data – ChemSpider and our archive of publications • Working with collaborators to define needs • Testing and enhancing deposition systems • Chemical validation & standardization platform • Analytical data handling formats • And lots in development…
  • 65. The Challenges Ahead • Chemistry is NOT just nicely defined structures! • Materials, minerals, attached to beads, polymers, ambiguous materials • Domain-specific measurements • File format standards are limited in application • Encouraging scientists to free up their data • AltMetrics, open data mandates, systems • The data explosion continues
  • 66. But it’s not easy of course • Not everything we would like around data handling is there for sure • Many systems, tools, platforms are already available but we don’t know about them or even if we did contributing us “more work” • “What’s in it for me?”, “It’s my data”, “It’s too much work”, “What credit do I get?”
  • 67. And yes…we know…
