## Description

## Ontology Info

| Field | Value |
|-------|-------|
| Acronyme | TMA |
| Description | Tissue microarrays (TMA) are enormously useful tools for translational research, but incompatibilities in database systems between various researchers and institutions prevent the efficient sharing of data that could help realize their full potential.  The Resource Description Framework (RDF) provides a flexible method to represent knowledge in triples, which take the form Subject-Predicate-Object.  All data resources are described using Uniform Resource Identifiers (URI), which are global in scope.  We present an OWL (Web Ontology Language) schema that expands upon the TMA data exchange specification to address this issue and assist in data sharing and integration. |
