Data ?
● Extend to any (digital) information used for a scientific communication :- raw sensor measures (input)- pre/post-processed measures (in/output)- simulated measures (output)- processing and simulation material→ any scientific material not published as texte→ software
● Different legal status,but researchers ≠ lawyers…

Reproducible Research
1200 ~ 1800Roger Bacon, Francis Bacon,Galileo Galilei, Robert Boyle,René Descartes, …
scientific method:science needs to be reproducible
1990 ~ …Jon Claerbout, David DonohoSerguei Fomel, Randy Leveque,Davis Bailey, Victoria Stodden,Juliana Freire, …
reproducible (computational) research:science is in the software, data and processing methods

Article/Data/Software
● Article : a narrative, a story told about some scientific development.
● Software (data) : the science told in the article.
● Software (data) need be managed like articles : identified, persistent, cited, accessible→ Amsterdam Data Citation Manifesto→ Science Code Manifesto

IPOL
IPOL is a research journal of image processing and image analysis. Each article contains a text describing an algorithm and source code, with an online demonstration facility and an archive of online experiments. The text and source code are peer-reviewed and the demonstration is controlled. IPOL is an Open Science and Reproducible Research journal.

Software in IPOL
● Mandatory
● Reviewed and controled
● Minimal, some technical & editorial rules
● Open license

Demo
CODE DEMO
● Open to anyone with a web browser
● Free input and parameters
● Exact same code, in real time
IPOL: ARTICLES, SOFTWARE AND DATA IN APPLIED MATHS — 22
Examples
● Denoising : NL-means
● Detection : Viola-Jones, LSD
● Segmentation : Snakes
● Inpainting : Total Variation
● Stereo : S2P

Factoids
● Since 2010:- 52 articles published- 25 preprints- 200+ citations (cf. Google Scholar...)- 75000 archives (170G, 1500 archives/demo)
● Statistics 2013:- 140000 visits- 15000 code and data download- 60000 demo runs, ½ on original data

Sustainability by Productivity
● Management cost : ~2 pers.
● Core IPOL community : ~25 pers.
● Output :- +15 articles/year- better algorithm analysis and software quality- provable performance- more grants and contracts
● Benefits of IPOL > 10 % team growth
IPOL: ARTICLES, SOFTWARE AND DATA IN APPLIED MATHS — 25
Conclusions
● Extended concept of “data”+ software+ non-experimental sciences
● Need to value work done on data and software→ via the journal system
● Being online is not enough;we need reviews and stable storage
● Good quality software (data) enables new workflows, better work, more partners & contacts
