Why I got interested in ISA-TAB
• FP7 ToxBank project (2011-2015)
http://toxbank.net/ • Database support for http://www.seurat-1.eu/ (highly heterogeneous biological experiments )
• ISA-TAB identified and accepted as a solution

ISA-TAB http://www.isa-tools.org/
The open source ISA metadata tracking tools help to manage an increasingly diverse set of life science, environmental and biomedical experiments that employing one or a combination of technologies. Built around the
‘Investigation’ (the project context), ‘Study’ (a unit of research) ‘Assay’ (analytical measurement) general-purpose Tabular format, the ISA tools helps you to provide rich description of the experimental
metadata (i.e. sample characteristics, technology
and measurement types, sample-to-data relationships)
so that the resulting data and discoveries are reproducible and reusable.

ISA-TAB-NANO 1.1 MATERIAL TEMPLATE FIELDS
ISA-TAB-NANO 1.2 RELEASE NOTES Modified the ISA-TAB-Nano 1.1 version to address user comments. • Removed the Material Linkage column from the Material File. The
Material Constituent column identifies the materials that are linked if the Material Linkage Type is specified.
• Modified the Material Linkage Type description to indicate that if the linkage type is an entrapment or encapsulation, the Material Type column can specify whether the constituent is entrapped or encapsulated.
• Rephrased Material File instructions as follows: "Materials of different chemical composition or physical characteristics should be described in separate Material files."
• Enhanced the definition of material Characteristics to indicate that nominal particle characteristics (or vendor supplied) should be included in the Material File as characteristics. Experimentally determined characteristics should be included in the Assay File.

DISCUSSION (+/-) What is the best approach describe nano materials in ISA-TAB? Sample identifiers in ISA-TAB are in principle not restricted to biological samples Biological samples characterisation are described in ISA-TAB without any
extension ISA-TAB practice to describing chemical compounds = ontology entry. What if –
no proper ontology entry; or batch identifier / composition (impurities, additivies) are important?
(Ideas) Chemical or material composition can be described without introducing ISA-
TAB extensions Generic types of materials could be defined in an ontology and used for
annotation similar to ChEBI ; or The OpenTox compound service plugin for ISACreator
https://github.com/ToxBank/toxbank-isa-plugin Material samples can follow the usual ISA-TAB rules

CONCLUSIONS ISA-TAB • (+)Very powerful and flexible data model • (describes the experimental graph) • (+)Ontology definition and annotation of all entities • (-)Metadata only; data files not standardized • (+)But we have experience in ToxBank in standardizing data files
(and converting to RDF) https://github.com/ToxBank/isa2rdf • (-)Data preparation time consuming, requires
knowledge of both data modelling and biological assays. Need of tools hiding the complexity.
ISA-TAB-Nano • (+)Extends ISA-TAB • (+/-)Is this the best approach describe NM in ISA-TAB? • (-)Under development • Tools not available, examples under development
