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.

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
