This returns one row for each work. Titles, authors, and subjects
are all optional. If they repeat, the repeated values are concatenated into
- a single field, separated by semicolons. This is done by the GROUP_DIGEST
- function that is specific to the Virtuoso back end.

- This example supports use attributes 4 (title), 1003 (author), 21 (subject),
- and 1016 (keyword) which matches any literal in a triplet that refers to the
- work, so it works for the titleValue in the workTitle, as well as the label
- in the subject, and what ever else there may be. Like the preceding example,
- the matching is by a simple substring, case sensitive. A more realistic term
- matching could be done with regular expressions, at the cost of some readability

Configuration for database "instance". Like "work" above this uses SELECT
to return row-based data, this time from the instances. This is not deduplicated,
- so if an instance has two titles, we get two rows, and if it also has
- two formats, we get four rows. The DISTINCT in the SELECT
