## Detailed Description

The libSBML “comp” extension implements support for the SBML Level 3 Hierarchical Model Composition package. It can be used in SBML Level 3 Version 1 and Version 2 documents.

## Introduction

In the context of SBML, hierarchical model composition refers to the ability to include models as submodels inside another model. The goal is to support the ability of modelers and software tools to do such things as (1) decompose larger models into smaller ones, as a way to manage complexity; (2) incorporate multiple instances of a given model within one or more enclosing models, to avoid literal duplication of repeated elements; and (3) create libraries of reusable, tested models, much as is done in software development and other engineering fields. SBML Level 3 Version 1 Core, by itself, has no direct support for allowing a model to include other models as submodels. The Level 3 Hierarchical Model Composition package adds the missing capabilities. The figure below illustrates some of the scenarios targeted by this package.

Two examples of model configuration supported by the “comp” package: (left) a model composed of a submodel that is itself composed of submodels; (right) a model composed of submodels, one of which is defined in an external file.

## Authors

The primary authors of the SBML Level 3 Hierarchical Model Composition specification are Lucian P. Smith, Michael Hucka, Stefan Hoops, Andrew Finney, Martin Ginkel, Chris J. Myers, Ion Moraru and Wolfram Liebermeister.

## The specification for this SBML package

This API documentation for libSBML does not provide a complete explanation of the SBML Level 3 Hierarchical Model Composition (“comp”) package. If you are developing software that uses “comp”, you are strongly urged to read the actual specification for the package. A link to the specification document current is provided below, along with a link to the page of known issues (if any). we apologise that our known issues pages are under reconstruction.
