This is a story about collaboration...

ISA

ISA

• Inconsistent data formats, experimental descriptions and results

Disparate Stem Cell Resources

Disparate Stem Cell Resources

• Inconsistent data formats, experimental descriptions and results

The Stem Cell Commons

• A shared data and analytical resource

• Bioinformatics support for research at the HSCI

• A community

Data repository

user community

General-purpose, configurable format, designed to support the use of several standards checklists, terminologies and conversions to (a growing number of) other me t ad a t a formats , u s ed by publ i c repositories, e.g.

MAGE-Tab

SRA-xml SOFT

Pride-xml

Rationale for developing ISA

Capture all salient features of the experimental workflow

Make annotation explicit and discoverable

Support data provenance tracking

Use community standards

Challenges• Changing research culture(s) to recognize the value

of data sharing

• Manually curating the data for consistency and completeness

• Managing large volumes of data

• Standardizing workflows

• Ensuring interoperability when integrating multiple systems and tools

• Technical complexity of software development effort
