This is a part of the effort to provide a standardized, extensible, scalable and machine-processable interface for the Registry of Standard Biological Parts. The idea of a Semantic Web data model seems to fit this goal. The success of developing a Synthetic Biology ontology depends in part on a good definition of the BioBricks abstraction hierarchy.
Semantic Web
RDF/XML, RDF Schema and OWL
"an initiative to enable cross-platform data exchange and reuse through well-defined ontologies and a common XML-based framework."
"The goal of the Semantic Web initiative is to create a universal medium for the exchange of data where data can be shared and processed by automated tools as well as by people." [10]
- allows to model real things, not just documents or database tables (knowledge representation)
- consists of statements about resources in the form of triples:
SUBJECT -> PROPERTY -> VALUE
- identifies every resource with a globally unique URI: don't say "color", say <http://example.com/2005/std6#col>
- allows “serendipitous reuse”: integration with data sources in other fields (“web join”)

Resource Description Framework (RDF)
Assertion of facts
<http://www.example.org/index.html> has a creator whose value is John Smith
Resources
RDF Schema
Vocabulary definitions
Resources
Web Ontology Language (OWL)
Relationships between vocabularies and other constraints
Resources
Ontologies
Controlled vocabulary of concepts and their relationships. Described using RDF Schema and OWL.
Examples:
- Dublin Core
- Namespace: http://purl.org/dc/elements/1.1/
- Properties: title, creator, publisher, identifier
- Gene Ontology
- Namespace: ftp://ftp.geneontology.org/pub/go/xml/dtd/go.dtd
- Properties: name, definition, isa, association, evidence
- Sequence Ontology: features on a nucleotide or protein sequence
- BioPAX: biological pathway data
- UniProt (planning)
- SBML uses CellML metadata to describe its elements. See also a message on SBML forum.
- BioModels database and Systems Biology Ontologies (SBO) project
