ISA Configurations consist of multiple XML files and are created in the ISAcreator configurator, the latest version is downloadable from the ISA GitHub site (https://github.com/ISA-tools/ISAconfigurator/downloads) or from the main ISA website (http://www.isa-tools.org).
The configurations are designed to meet the requirements of one or more checklist(s) ( [http://www.mibbi.org minimum information), specifying the required fields, and/or enabling values to be drawn from a set of ontology terms.
All available configurations produced by the ISA tools team and collaborators (ISA commons, http://isacommons.org/) can be viewed via a table at the dedicated ISA-tools Configuration File page (http://www.isa-tools.org/format/configurations/)
Some configurations are also available at: (https://github.com/ISA-tools/Configuration-Files/wiki/ISA-tools-Configuration-Files)
An ISA configuration is comprised of a set of XML files following a schema available here https://github.com/ISA-tools/ISAvalidator-ISAconverter-BIImanager/blob/master/import_layer/src/main/resources/xsd/isatab_configurator.xsd
Contact the ISA team ([http://www.isa-tools.org/contact.html) if you need a new configuration that fit your specific needs, e.g. a different fields, or checklist, or set of ontologies/controlled vocabularies.
