(schema-triples

The tables clause specifies the database tables to be joined to
construct the view to be dumped. TABLE must be either of the form
TABLE-NAME or of the form (JOIN-OPERATOR TABLE-NAME
RAW-CONDITION). TABLE-NAME must, obviously, be the name of the
table. JOIN-OPERATOR must be one of join, left-join and
inner-join. RAW-CONDITION should be the join condition as a raw
string. This is usually something like
\"USING (SpeciesId)\". RAW-FORMS are expressions that must evaluate to
strings to be appended to the SQL query.
The schema-triples clause specifies the list of triples to be written
once when the dump starts.
The triples clause specifies the triples to be dumped once for each
row in the view. All triples have a common SUBJECT. The (verb
predicate object) clauses are described below.
VERB must either be set or multiset. For the set VERB, a single triple
(SUBJECT PREDICATE OBJECT-VALUE) is written where OBJECT-VALUE is the
result of evaluating OBJECT. For the multiset VERB, OBJECT must
evaluate to a list, and a triple (SUBJECT PREDICATE
OBJECT-VALUE-ELEMENT) is created for each element OBJECT-VALUE-ELEMENT
of that list.
The SUBJECT and OBJECT expressions in the triples clause must
reference database fields using a (field TABLE COLUMN) clause where
TABLE and COLUMN refer to the table and column of the field being
referenced. Database fields can also be referenced using (field TABLE
COLUMN ALIAS) where ALIAS is an alias for that column in the SQL
query. Specification of ALIAS is indeed a leak in the abstraction, and
must be remedied."
