Growing, worldwide movement for reproducible research

“Publicly-funded research data are a public good, produced in the public interest”

“Publicly-funded research data should be openly available to the maximum extent possible”

Shared, annotated research data and methods offer new discovery opportunities and prevent unnecessary repetition of work.

Improved data sharing underpins science of the future

§  Researchers and bioinformaticians in both academic and commercial science, along with funding agencies and publishers, embrace the concept that community-developed standards are pivotal to structure and enrich the annotation of

•  entities of interest (e.g., genes, metabolites, phenotypes) and •  experimental steps (e.g., provenance of study materials,

technology and measurement types)

esoteric formats

hoc or proprietary terminology

lack of sufficient contextual

information

comprehensible?

interoperable?

reusable?

reproducible?

Example from the toxicogenomics domain

Study looking at the effect of a compound inducing liver damage by characterizing/measuring

- the metabolic profile by MS and NMR

- protein expression in liver by MS

- gene expression by DNA microarray

-  conducting genetic and phenotypical analysis

Information contributing to the construction and validation of system biology models

Example of experiments by InnoMed PredTox a FP6 public-private consortium

§  Capture all salient features of the experimental workflow

§  Make annotation explicit and discoverable

§  Structure the descriptions for consistency, tracking §  independent variables §  dependent variables using §  cross reference and

resolvable identifiers

Structured description of datasets

§  We must strike a balance between •  depth and breadth of

information; and •  sufficient information

required to reuse the data

Not too much, not too little, just ‘right’

Information intensive experiments

To make the experiments comprehensible and reusable,

underpinning future investigations, we need

common ways to report and share the experimental details and the associated data.

Consistent reporting will have a positive and long-lasting impact

on the value of collective scientific outputs.

Information intensive experiments

§ The challenges we face

•  Large in volume: lots of data types and metadata! •  Lots of free text descriptions: hard to mine, subject to mistakes! •  Babel of terminologies: lack of definitions, hard to map! •  Heterogeneous file formats: software lock-in!

§ Need for reporting standards •  Minimal reporting descriptors

- Report the same ‘core essentials’ •  Controlled vocabularies or ontology

- Use the same word and mean the same thing •  Common exchange formats

- Make tools interoperable, allow data exchange and integration

Common ways to report and share

§  Describe and communicate the information to others, in an unambiguous manner

§  To unlock the value in the data •  Compare, query and evaluate data

- Facilitate scientific validation of the findings •  Understand variability within/between different technologies and

protocols -  Facilitate technical validation -  Enable optimization of the experimental designs -  Identify critical checkpoints and develop quality metrics

§  To define submission and/or publication requirements •  Journals •  Databases

§  To ensure data integrity, reproducibility and (re)use

Escalating number of standardization efforts in bioscience, e.g.:

Enzymology data standards

www.strenda.org

Different community, different norms and standards, e.g.:

report the same core, essential information

use the same word and refer to the same ‘thing’ allow data to flow from

one system to another

Challenges: lack of coordination, fragmentation and uneven coverage

Is this ‘general mobilization’ good or bad?

§  Difference in structures and processes: •  organization types (open, close to members, society, WG…) •  standards development (how to design, develop, evaluate, maintain…) •  adoption, uptake, outreach (link to journals, funders, commercial sector…) •  funds (sponsors, memberships, grants, volunteering…)

§  Fragmentation of the standards is a major issue •  Being focused on particular communities’ interests, be their individual

technologies or biological/biomedical disciplines, leads to duplication of effort, and more seriously, the development of (largely arbitrarily) different standards

•  This severely hinders the interoperability of databases and tools and ultimately the integration of datasets

Is this ‘general mobilization’ good or bad?

To integrate data we need interoperable standards

§  Promote synergies •  Among basic academic (omics) research but also regulatory- or

healthcare-driven initiatives

§  Much could be learned from exchange of ideas and practices •  Although, regulatory- or healthcare-driven initiatives have far stricter

guidelines

•  Although, often SDOs have ‘close’ discussions, require membership

§  Create interoperable standards •  Fit neatly into a jigsaw, resolving inconsistency and filling gaps

§  Overcome several barriers •  Technical

•  Funding issue

•  Sociological......

Need to address the fragmentation

“Any customer can have a car painted any colour that he wants so long as it is black” Henry Ford, you know who he is…

“Biologists would rather share their toothbrush than their gene name” Michael Ashburner, Professor Genetics, University of Cambridge, UK

Eloquent quotes

§  Buying nuts and bolts is easy today •  But in the 19th century it was very complicated!

Standards – an old issue, e.g. engineering in 1850

§  Buying nuts and bolts is easy today •  But in the 19th century it was very complicated!

§  Nuts and bolts were custom made •  Products from different shops were incompatible •  Craftsmen liked the monopoly

- Customers were ‘locked in’ !!

§  In 1864 William Sellers initiated the standardization •  Mass production •  Get interchangeable parts •  Standardized way to make nuts and bolts

§  Generally adopted only after WWII, though …. !!

Standards – an old issue, e.g. engineering in 1850

Social engeneering

Ownership of open standards can be problematic in broad, grass-root collaborations; it

requires improved models, to encourage maintenance of and contributions to these efforts,

supporting their evolutions

The extensive community liaison needs to be managed

and funded; rewards and incentives need to be identified

for all contributors

The cost of implementing a standards-supported data

sharing vision is as large as the number of stakeholders that must operate synchronously

§ Several data preservation, management and sharing policies have emerged in response to increased funding for omics domains

§ Even if in general terms, standards are recognized as necessary ‘tools’ to unambiguously represent, describe and communicate research data

1. Funders actively developing data policies

§  “… lack of standardized data affects CDER’s review processes by curtailing a reviewer’s ability to perform integral tasks such as rapid acquisition, storage, analysis......efficient management of a portfolio of standards projects will require coordinated efforts and clear roles for multiple participants within/outside FDA”

2. Similar trend in the regulatory arena

§ Continue to support the development of open standards and tools •  to support sharing of sufficiently well annotated datasets •  to enable comprehensible, reusable, reproducible research

3. Publishes have become strong advocators

….the rise of data-driven journals, e.g.:

partnering with:

The rise of data-driven journals, e.g.:

partnering with:

§ R&D has invested heavily in procedures and tools that integrate external information with their own data to enhance the decision-making process

•  Now joining forces to streamline non-competitive elements of the life science workflow by the specification of common standards, business terms, relationships and processes

4. Similar trend in the commercial sector

Which one are mature enough for

me to use or recommend?

I work on plants, are these just for

biomedical applications?

What are the criteria to evaluate

their status and value?

How can I get involved to

propose extensions or modifications?

Which tools and databases

implement which standards?

I use high throughput sequencing technologies, which one are applicable

to me?

§  A bewildering array of standards is available, but

•  these are hard to find, at different levels of maturity; in

some areas duplications or gaps in coverage also exist

§  Standards are just a ‘means to an end’, therefore

•  we want to make them discoverable and accessible,

maximizing their use to assist the virtuous data cycle,

from generation to standardization through publication to

subsequent sharing and reuse

ISA software suite: supporting standards-compliant experimental annotation and enabling curation at the community level

Create template(s) to fit the type of experiments to be described

Create templates detailing the steps to be reported for different investigations, complying to community standards, e.g. configuring the value(s) allowed for each field to be •  text (with/without regular expression testing), •  ontology terms, •  numbers etc.

Describe, curate your experiment with geographically- distributed collaborators

Report and edit the description of the investigation using customized Google Spreadsheets (importing the ‘template’ created by the ISA configurator) enabled with ontology search and term-tagging features.

Or describe, curate your experiment using a desktop-based tool

Report and edit the description using this tool, (also customized using the templates) with a spreadsheet like look and feel, packed with functionalities such as • ontology search (access via ) • term-tagging features • import from spreadsheets etc…

Notes in Lab Books(information for humans)

Spreadsheets and Tables( the compromise)

Facts as RDF statements(information for machines)

We must increase the level of annotation

•  Invest in curating and manage data at the source using: •  a common metadata tracking framework, such as ISA •  publicly available and community-developed terminologies •  recording sufficient contextual information of the experimental steps

§  Progressively datasets will become more comprehensible, interoperable, reproducible and (re)usable, underpinning future investigations
