Protein Ontology Project in 2007: Looking Backward and Forward

Protein ontology is designed to provide a structured protein data specification for protein data representation. Protein ontology is a standard for representing protein data in a way that helps in defining data integration and data mining models for protein structure and function. In paper we summarize the development of PO that we discussed in previous chapters. A large number of diverse bioinformatics sources are available today. The future of biological sciences promises more data. No individual data source will provide us with answers to queries that we need to ask. Instead knowledge has to be composed from multiple data sources to answer the queries. Even though multiple databases may cover same data their focus might be different. Thus, protein ontology project is an ongoing project with creation of every new protein data source. We also outline here in this paper the future work that we will be doing in protein ontology project.
