Maintaining pharmacogenomics knowledge bases is challenging due to evolving ontologies and relational data. This study introduces a method using XML schema to interface ontologies with relational data sources, enabling automated updates and data integration.

Area of Science:

  • Bioinformatics
  • Computational Biology
  • Genomics

Background:

  • Ontologies are crucial for organizing complex pharmacogenomic data.
  • Maintaining stable mappings between evolving ontologies and static relational data sources is time-consuming.

Purpose of the Study:

  • To develop a method for interfacing ontology models with data acquisition from external relational data sources.
  • To automate updates of links between ontologies and data acquisition when ontologies change.
  • To import genetic sequence data into a pharmacogenetics ontology.

Main Methods:

  • Utilized a declarative interface modeled in the ontology and implemented using XML schema.
  • Imported relational data into the ontology using XML.
  • Ensured data integrity by validating XML submissions against XML schema.

  • Implemented the approach in the PharmGKB knowledge base.

    • Main Results:

    • Successfully imported genetic sequence data from a relational model into the pharmacogenetics ontology.
    • Demonstrated rapid updating of the interface when the ontology evolved.
    • Automated the process of updating links between the ontology and data acquisition.

    Conclusions:

    • The proposed method effectively interfaces ontology models with relational data sources.
    • This approach facilitates automated updates and robust data integration for pharmacogenetics knowledge bases.
    • Similar methods can integrate diverse, heterogeneous information sources for computational analysis.
