rdfs:isDefinedBy | https://raw.githubusercontent.com/vgteam/vg/master/src/vg.proto
rdfs:label | Alignment
rdfs:subClassOf | http://edamontology.org/format_2055

vg:GBWT_Format (rdf:type owl:Class )
rdfs:comment | Graph Burrows-Wheeler Transform, a succinct collection of paths through a genome graph, published by Jouni Siren. Usually represents haplotypes.
rdfs:isDefinedBy | https://raw.githubusercontent.com/vgteam/vg/master/src/vg.proto
rdfs:label | GBWT

vg:GCSA2_Format (rdf:type owl:Class )
rdfs:comment | Generalized compressed suffix array 2, an exact match index published by Jouni Siren
rdfs:isDefinedBy | https://raw.githubusercontent.com/vgteam/vg/master/src/vg.proto
rdfs:label | GCSA2

vg:Node (rdf:type owl:Class )
rdfs:comment | "A node in the variant graph, representing a sequence section." xsd:string
rdfs:label | "Node" xsd:string
rdfs:subClassOf | owl:Thing

vg:Path (rdf:type owl:Class )
rdfs:comment | "A Path is a collection of steps from path to path that represent an asserdfs:labelmbled sequence integrated into the variant grap." xsd:string
rdfs:label | "Path" xsd:string
rdfs:subClassOf | owl:Thing

vg:Snarl_Format (rdf:type owl:Class )
rdfs:comment | A series of Snarl objects, each of which contain: The boundaries of a snarl (a bubble-like motif in a graph), the snarl (if any) that contains this one, classifications of the snarl based on the reachability of the two boundary nodes from each other and the cyclic-ness of the subcomponent.
rdfs:isDefinedBy | https://raw.githubusercontent.com/vgteam/vg/master/src/vg.proto
rdfs:label | Snarl

vg:Snarl_Traversal_Format (rdf:type owl:Class )
rdfs:comment | A series of SnarlTraversal objects, each of which contain: A walk in the graph through a Snarl, and optionally a name.
rdfs:isDefinedBy | https://raw.githubusercontent.com/vgteam/vg/master/src/vg.proto
rdfs:label | SnarlTraversal

vg:Step (rdf:type owl:Class )
rdfs:comment | "A step along a path in the variant graph. A series of steps along a path represent an assembled sequence that was originally inserted into the the variant graph. A step points to a :Node or the reverse complement of a node and has a rank (step number)." xsd:string
rdfs:label | "Step" xsd:string
rdfs:subClassOf | owl:Thing

vg:VG_Format (rdf:type owl:Class )
rdfs:comment | Consists of nodes, edges, and paths. Nodes each have a unique ID and a DNA sequence, edges consist of two node sides (so the graph is bidirected), and paths are a sequence of nodes and orientations. Paths also have names.
rdfs:isDefinedBy | https://raw.githubusercontent.com/vgteam/vg/master/src/vg.proto
rdfs:label | Graph
rdfs:subClassOf | http://edamontology.org/format_2055
rdfs:subClassOf | http://edamontology.org/format_2921

vg:XG_Format (rdf:type owl:Class )
rdfs:comment | An immutable, succinct representation of a graph. Contains the same info as the .vg.
rdfs:isDefinedBy | https://raw.githubusercontent.com/vgteam/vg/master/src/vg.proto
rdfs:label | XG
rdfs:seeAlso | vg:VG_Format
