Template:ChadoTable cvterm

Jump to: navigation, search

This template is a Chado Table Template. It defines a single table from the Chado schema, and every Chado table has a template like this one. This template is automatically included in two places:

  1. The module page for the module the table is a part of. This is where updates and comments should be posted.
  2. The Chado Tables page, which lists all tables.

You can include this template anywhere you want to show the table description.

Boolean 0=false,1=true; see GO documentation for details of obsoletion. Note that two terms with different primary dbxrefs may exist if one is obsolete.

is_relationshiptype integer NOT NULL

Boolean 0=false,1=true relations or relationship types (also known as Typedefs in OBO format, or as properties or slots) form a cv/ontology in themselves. We use this flag to indicate whether this cvterm is an actual term/class/universal or a relation. Relations may be drawn from the OBO Relations ontology, but are not exclusively drawn from there.
