GlycoCoO

GlycoCoO provides a standardized semantic ontology for representing glycoproteins, glycolipids, glycans, glycoforms, and glycosylation sites to enable consistent digital representation, quantitative storage of abundances or ratios, and integration via triplestores.

Key Features:

• Standardized Representation: Represents glycans as complete structures or compositions to capture detailed glycoprotein and glycolipid structure information across experimental methods.
• Glycoform Annotation: Encodes glycoforms attached to specific glycosylation sites for precise site-level annotation.
• Handling Incomplete Data: Supports representation of partially missing site information when site mapping has not been performed.
• Quantitative Data Storage: Stores abundances or ratios of glycans within specific glycoforms at particular sites to enable quantitative comparison.
• Data Exchange and Integration: Enables representation in triplestores to facilitate interoperability and data exchange between databases and repositories.

Scientific Applications:

• Standardized Annotation: Provides a consistent framework for annotating glycoprotein and glycolipid structures in digital datasets.
• Quantitative Glycoproteomics: Supports storage and comparison of glycan abundances or ratios for quantitative analyses of glycoforms at sites.
• Data Integration: Facilitates integration and interoperability of glycoproteomics data across triplestores and databases.
• Glycosylation Interpretation: Enables structured representation that supports interpretation of glycosylation patterns and their biological implications.

Methodology:

Implemented as an ontology intended for integration into triplestores to provide semantic representation of glycoproteomics data and enable semantic queries and analyses.
