The author, reference or category of a comment. Used to help parse pathway-level comments, e.g., the descriptions displayed at WikiPathways.org are comments with source="WikiPathways-description".
RelY is the y-coordinate used when a point or state is linked to a another object - relative coordinate to the object that it is linked to (0,0 - center, 1,1 - bottom-right).
RelX is the x-coordinate used when a point or state is linked to a another object - relative coordinate to the object that it is linked to (0,0 - center, 1,1 - bottom-right).
A GraphId is a unique (per Pathway) identifier for a pathway element, such as DataNode, Interaction, GraphicalLine, Label, Point, Group, Shape, State and Anchor.
A GraphRef indicates a "depends on" or child/parent relationship between two Pathway elements. The element with the GraphRef is the child, and the element referred to by the GraphRef is the parent. The parent's GraphId will be specified by the child's GraphRef.
Currently: Specifies the glyph (graphical representation) to use for GPML elements (DataNode, Label, Shape, State).
Proposed: Expand it to also describe Anchors. It should replace the term currently used to specify the graphical representation of an Anchor. The current term is "Shape," which conflicts with the GPML element named "Shape." See details for term "Shape."
A GroupRef indicates that its element is part of the gpml:Group with the specified GroupId.
DataNode, GraphicalLine, Group, Interaction, Label and Shape can be part of a group.
A graph diagram representing a biological process as a set of interactions and relationships among genes, proteins, metabolites, and other factors in the context of cellular compartments, tissues and organisms.
A visual annotation, often used to partition space or connect other annotation, e.g., Shapes. An Xref can not be specified for GraphicalLines (in contrast to Interactions).
Denotes a biological entity that forms a node in a pathway and has some biological meaning associated with it. For a list of the gpml:DataNode types supported at WikiPathways, see subclasses of wp:DataNode or the wpTypes vocabulary defined for use in applications..
Reference to a database entry that matches the node
in the pathway. It is a combination of an identifier of the entity and an
identifier of the database in which the entity is found.
Defines the biochemical relationship between DataNodes or with Anchors on other Interactions. An Xref can be specified for Interactions (in contrast to GraphicalLines).
