db_display_name to "GOSlim GOA".

as well as about how to build the latter.

The script adds one table by subset previously added to the database and
maps all terms to the closest term within that subset.  The tables are
named "aux_XX_YY_map" where "XX" is the ontology ("GO" or "SO"), and
"YY" is the subset name (e.g., "goslim_goa").

The schema for each of the subset map tables is simply as follows:

  +----------------+------------------+------+-----+---------+-------+
  | Field          | Type             | Null | Key | Default | Extra |
  +----------------+------------------+------+-----+---------+-------+
  | term_id        | int(10) unsigned | NO   | PRI | NULL    |       |
  | subset_term_id | int(10) unsigned | NO   | PRI | NULL    |       |
  +----------------+------------------+------+-----+---------+-------+

... where both fields refers into the 'term' table.

+  Arg [2]       : (optional) String
+                  The subset within the ontolgy to which the query
+                  should be restricted.  The subset may be specified
+                  as a SQL pattern, e.g., "goslim%".
+
+  Arg [3]       : (optional) Boolean
+                  If true (non-zero), only return the closest
+                  terms.  If this argument is true, and the previous
+                  argument is left undefined, this method will
+                  return the parents of the given term.
+
+  Description   : Given a child ontology term, returns a list of
+                  all its ancestor terms, up to and including any
+                  root term.  Relations of the type 'is_a' and
+                  'part_of' are followed.  Optionally, only terms in
+                  a given subset of the ontology may be returned,
+                  and additionally one may ask to only get the
+                  closest term(s) to the given child term.
