Event description


This Symposium with accompanying workshops builds on recent events to expand and prioritise future developments for the IUPAC InChI standard for chemical structure representation.

The event will include a mix of themed talks on use cases and working breakout sessions, finishing with summaries and actions. Please indicate in the event sign-up if you would like to be a speaker - short talks around use cases especially welcome.

Planned sessions and topics are:

Plenary Sessions

  • Overall InChI direction

  • IUPAC InChI Subcommittee

  • InChI Use Cases - flash talks from attendees

  • InChI Project Updates

Breakout topics

  • InChI Open Education Resources

  • Broadening Community engagement

    • Infrastructure Providers

    • Industry

    • Researchers

  • Large Molecules - complementarity w/ HELM, w/ Mixtures

  • Resolver - Use Cases

  • Organometallics

  • IUPAC SMILES+ project (and how related to InChI community)

Panel Discussions

  • Open Source Development

  • InChI v2 - what is it?

  • Complementarity of other formats (SMILES, CTAB, graphical representation stds)

  • Feedback on InChI challenges and limitations

  • Discussion of priorities for further development

  • Plans for publication and dissemination - thematic journal issue?

  • InChI Shark’s Den / Dragon Tank

Project Updates

  • RInChI

  • Organometallics

  • Variability

  • Education - InChI OER


  • HELM - current status

  • QR Codes

  • Resolver
