CDAOStore: A Phylogenetic Repository Using Logic Programming and Web Services

Download Now Free registration required

Executive Summary

The CDAOStore is a portal aimed at facilitating the storage and retrieval of data and metadata associated to studies in the field of evolutionary biology and phylogenetic analysis. The novelty of CDAOStore lies in the use of a semantic-based approach to the storage and querying of data. This enables CDAOStore to overcome the data format restrictions and complexities of other repositories (e.g., TreeBase) and to provide a domain-specific query interface, derived from studies of querying requirements for phylogenetic databases. CDAOStore represents the first full implementation of the EvoIO stack, an inter-operation stack composed of a formal ontology (the Comparative Data Analysis Ontology), an XML exchange format (NeXML), and a web services API (PhyloWS).
