1 Knowledge Enabled Information and Services Science Glycomics project overview

2 Knowledge Enabled Information and Services Science Life Science Ontologies ProPreO An ontology for capturing process and lifecycle information related to proteomic experiments 398 classes, 32 relationships 3.1 million instances Published through the National Center for Biomedical Ontology (NCBO) and Open Biomedical Ontologies (OBO) Glyco An ontology for structure and function of Glycopeptides 573 classes, 113 relationships Published through the National Center for Biomedical Ontology (NCBO)

3 Knowledge Enabled Information and Services Science Two aspects of glycoproteomics: oWhat is it? → identification oHow much of it is there? → quantification Heterogeneity in data generation process, instrumental parameters, formats Need data and process provenance → ontology-mediated provenance Hence, ProPreO models both the glycoproteomics experimental process and attendant data ProPreO ontology
