Department of Bioinformatics - BiGCaT 1
An architecture for anOpen Sciencemolecular compound database

This session: Public Databases ...
• Public: what's that?– free access?– redistribute?–Modify?
• BTW, what is “Open Access” ???
Department of Bioinformatics - BiGCaT 3
This session: Serving the community...
• Service–What do people want?–Do they know what is possible?
• Community–Who are they? Personas!→–Usability must include learnability
Department of Bioinformatics - BiGCaT 4
Personas
• Not every scientist is alike• You cannot and must not target one
user• Instead, target at least 2 different
users, particularly:–The hacker doing all the actual
bioinformatics in the lab–The professor who has too little time to
understand things outside his narrow field

Reason #1: Bioclipse decision support
Spjuth, O. et al. JCIM 2011 51(8):1840-1847.

Data #1: Linked Open Drug Data
M. Samwald, et al, Linked open drug data for pharmaceutical research and development, 2011, JChemInf.

Data^2: Linked Open Data

Reason #2: Publishing
• Journals will increasingly require data deposition–e.g. BioMed Central:
Department of Bioinformatics - BiGCaT 12
Needs
• We must propagate rights–whether open or not!
• We must make things explicit–e.g. by using semantics–e.g. by using the InChI
Department of Bioinformatics - BiGCaT 13
Tool #1: licensing
Department of Bioinformatics - BiGCaT 14
Open Data #1: crystallography
Department of Bioinformatics - BiGCaT 15
Open Data #2: Open Notebook Science
Department of Bioinformatics - BiGCaT 16
Open Data #3: CrystalEye
Department of Bioinformatics - BiGCaT 17
Licensing Open not Required→
• But not providing info is a killer–no, not really because
no scientist seems to care
–yes, because how will a machine do? Think scalability and massive data integration efforts
Department of Bioinformatics - BiGCaT 18
Why does explicit licensing matter?
Because when there is a fire, you want immediate access to the fire hose. You do not want to wait for permission from the mayor.
Because when you like to validate your scientific results, you want immediate access to related data. You do not want to wait for permission from that professor who is on a conference tour for the next 4 weeks. You must have an immediate answer, whatever it is.

Tool #2: Semantic Web to the rescue
• Allows provenance–provide where data came from– tells us our rights
Department of Bioinformatics - BiGCaT 20
App #1: Spidering the semantic web
Spjuth, O et al. JChemInf 2013 5:14.
Department of Bioinformatics - BiGCaT 21
App #2: Making a web

App #3: Open PHACTS Explorer

How #1: RDF Graphs

Is that it?!? Just an architecture??
Yes, but a simple and flexible one. Keep an eye out on my blog. This will happen in the next few months:
1. Aggregate all CCZero/PDDL data around chemical properties
1.Open Notebook Science (solubility, melting point)
2.ChemPedia
3.Crystallography (COD, CrystalEye)
4....
2. Calculate molecular properties with the CDK (and release as CCZero)
3. Host on http://linkedchemistry.info/chembox

Architecture
Triple Store(e.g. Virtuoso)
Web server(HTML / RDF)
• Graphs• Explicit license
info• InChI/FixedH
Department of Bioinformatics - BiGCaT 30
/FixedH ?!?!
Department of Bioinformatics - BiGCaT 31
Conclusions & Outlook
• We must propagate rights–whether open or not!
• We must make things explicit–e.g. by using semantics–e.g. by using the InChI with FixedH
