/* This file contains the configuration for triplify.
* Triplify rapidly simplifies the creation of structured content for Web 2.0
* mashups and Semantic Web applications.
*
* Triplyfy is based on the definition of a number of SQL queries, whose
* results are converted into either RDF/N3, JSON or Linked Data.
/* Triplify uses URIs to identify objects. In order to simplify their handling
* you should define shortcuts (i.e. namespace prefixes) for all namespaces
* from which you want to use URIs.
/* The core of triplify are SQL queries, which select the information to be made
* available.
* You can provide a number of arbitrary queries. Each query, however, should
* select information about an object of a certain type. This type, which serves
* as an index in the associative queries configuration array, is also used to
* construct corresponding URIs for the objects returned by the query.
* The first column returned by the query represents the ID of the object and
* has to be named “id”, all other columns represent characteristics (or
* properties of this object). As column identifier you should reuse existing
* vocabularies whenever possible.
/* Some of the columns of the Triplify queries will contain references to other
* objects rather than literal values. The following configuration array
* specifies, which columns are references to objects of which type.
/* Objects are classified according to their type. However, you can specify
* a mapping here, if objects of a certain type should be associated with a
* different class (e.g. classify all users as 'foaf:person'). If you are
* unsure it is safe to leave this configuration array empty.
/* You can specify for how long generated files should be cached. For smaller
* Web applications it is save to disable caching by setting this value to zero.
/* Triplify uses a PDO object to connect to the database.
