OLS Client and OLS Dialog: Open Source Tools to Annotate Public Omics Datasets.

Area of Science:

• Bioinformatics
• Computational Biology
• Data Management

Background:

• User-friendly software for annotating biological datasets is crucial for data management.
• The Ontology Lookup Service (OLS) is a key resource for biomedical ontologies.
• OLS version 3.0 is a major redevelopment, incompatible with previous versions, necessitating new access tools.

Purpose of the Study:

• To provide software solutions for accessing the new Ontology Lookup Service (OLS) version 3.0.
• To facilitate the integration of OLS data into bioinformatics resources and data annotation tools.

Main Methods:

• Development of OLS Client, a free, open-source Java library for programmatic access to OLS 3.0.
• Creation of OLS Dialog version 2.0, a Java graphical user interface for desktop applications.
• Ensuring a robust, pluggable programming interface and common data model.

Main Results:

• The OLS Client library enables rapid tool creation for accessing OLS 3.0.
• The OLS Dialog provides an easily integrable GUI for OLS access.
• Both tools have been integrated into existing bioinformatics resources and data annotation tools.

Conclusions:

• The OLS Client and OLS Dialog address the need for updated software to access the redeveloped OLS framework.
• These tools enhance data management and annotation capabilities in bioinformatics.
• The open-source nature promotes wider adoption and integration within the scientific community.
