public class TabDelimParser extends Object
The tab-delimited ontology files have three types of lines. Lines that are
pure white space can be discarded. Comment lines begin with a hash (#) and
can be discarded. The payload lines contain three fields seperated by tabs.
By convention, the content of each field contains no spaces.
By convention, if there are comment lines beginning with
description: and these appear before any predicate
declarations then they become the name and description of the ontology.
Otherwise, the name and description will be the empty string.
Term names normally will be just a term name like
person. There are also terms that represent collections of
triples. For example, here is the declaration for the 'triple' type in
the core ontology.
... triple is-a any triple has-a source triple has-a target triple has-a predicate (triple,has-a,any) size 3 ...
The first four lines just associate triple with some type with a predicate
(e.g. is-a or has-a). The fifth line says that something must have a size of
three. The 'something' is
(triple,has-a,any) size 3 and is
short-hand for a collection of triples that state that the source must be
triple, the target must be
any and the predicate
has-a. This whole expression states that a triple
has exactly three has-a relationships; that is, exactly three properties.
