Minimum information required in the annotation of models


MIRIAM is a community-level effort to standardize the annotation and curation processes of quantitative models of biological systems. It consists of a set of guidelines suitable for use with any structured format, allowing different groups to collaborate and share resulting models. Adherence to these guidelines also facilitates the sharing of software and service infrastructures built upon modeling activities.
The idea of "a set of good practices" including "some obligatory metadata" was first proposed by Nicolas Le Novère in October 2004 as part of a discussion to develop a common database of models in systems biology. These initial ideas were further refined at a meeting in Heidelberg, during ICSB 2004, with representatives from many other interested groups.
MIRIAM is a registered project of the MIBBI.

MIRIAM Guidelines

The MIRIAM Guidelines are composed of three parts, reference correspondence, attribution annotation, and external resource annotation, each of which deals with a different aspect of information that should be included within a model.

Attribution annotation

'Attribution annotation' deals with the attribution information that must be embedded within the model file.
'External resource annotation' defines the manner in which annotations should be constructed. Those annotations contain references to entities in databases, classifications, ontologies, etc. One of the purposes of annotation is to allow unambiguous identification of the various model components.
More information about the existing qualifiers is available from BioModels.net.
So far, annotation is mainly a manual work, so to ensure their longevity the usage of perennial URIs is necessary. It was recognised that the generation of valid and unique URIs for annotation required the creation of a catalogue of shared namespaces for use by the community. This function is provided by the MIRIAM Registry. The Registry also provides a variety of supporting auxiliary features to enable automated procedures based upon these URIs. The ability to generate resolvable identifiers is provided through the use of the resolving layer, Identifiers.org.
