Generic Model Organism Database
The Generic Model Organism Database (GMOD) project provides biological research communities with a toolkit of open-source software components for visualizing, annotating, managing, and storing biological data. The GMOD project is funded by the United States National Institutes of Health, National Science Foundation and the USDA Agricultural Research Service.
History
The GMOD project was started in the early 2000s as a collaboration between several model organisms databases (MODs) who shared a need to create similar software tools for processing data from sequencing projects. MODs, or organism-specific databases, describe genome and other information about important experimental organisms in the life sciences and capture the large volumes of data and information being generated by modern biology. Rather than each group designing their own solutions in-house, four major MODs--FlyBase, Saccharomyces Genome Database, Mouse Genome Database, and WormBase—worked together to create a set of software applications that provide functionality needed by all MODs, such as software to help manage the data within the MOD, and to help users access and query the data.
An important part of the GMOD project is ensuring that the software components are interoperable. To this end, many of the tools use a common input/output file format or run off a Chado schema database.
Chado database schema
The Chado schema aims to cover many of the classes of data frequently used by modern biologists, from genetic data to phylogenetic trees to publications to organisms to microarray data to IDs to RNA/protein expression. Chado makes extensive use of controlled vocabularies to type all entities in the database; for example: genes, transcripts, exons, transposable elements, etc., are stored in a feature table, with the type provided by the Sequence Ontology. When a new type is added to the Sequence Ontology, the feature table requires no modification, only an update of the data in the database. The same is largely true of analysis data that can be stored in Chado as well.
The existing core modules of Chado are:
- sequence - for sequences/features
- cv - for controlled-vocabs/ontologies
- general - currently just dbxrefs
- organism - taxonomic data
- pub - publication and references
- companalysis - augments sequence module with computational analysis data
- map - non-sequence maps
- genetic - genetic and phenotypic data
- expression - gene expression
- natural diversity - population data
