Glossary of Terms¶
- Glycan¶
A molecule composed of saccharide units and substituents
- Monosaccharide¶
A single saccharide unit which is composed of a carbon backbone with hydroxyl side chains or substituent groups.
- Topological Matching¶
When discussing a topological matching traversal, the algorithm does not check whether the precise connection locations of edges match, just that there exists an edge which connects a matching parent node to a matching child node between two trees/graphs. This is particularly useful when unknown linkages are present. For example,
a-D-Neup5Ac-(2-3)-b-D-Galp-(1-3)-b-D-Glcp2NAc
would matcha-D-Neup5Ac-(2-6)-b-D-Galp-(1-3)-b-D-Glcp2NAc
despite the difference in the linkage betweena-D-Neup5Ac
andb-D-Galp
. The alternative is a Exact Matching traversal.- Exact Matching¶
When discussing an exact matching traversal, the algorithm requires that the positions of all connections of matching nodes between two trees/graphs must also match to be considered a full match. For example,
a-D-Neup5Ac-(2-3)-b-D-Galp-(1-3)-b-D-Glcp2NAc
would not matcha-D-Neup5Ac-(2-6)-b-D-Galp-(1-3)-b-D-Glcp2NAc
because of the difference in the linkage betweena-D-Neup5Ac
andb-D-Galp
.- RDF¶
Resource Description Framework (RDF) is a web technology standard for specifying a semantic description of data. It is used by the glySpace project and affiliated databases to represent glycans, glycoconjugates, and related entities.
- SPARQL¶
SPARQL is a query language for rdf.
