169 *
170 * This function checks whether the database corresponds to the given schema.
171 * The schema contains a list of required and optional point attributes and
172 * metadata entries and is given in JSON format. Primary point attributes
173 * are marked with a "*", optional attributes or metadata entries are
174 * marked with a "?" appended to the name, all other items are required.
175 *
176 * The database must at least contain all primary and required point attributes
177 * and all required metadata entries to correspond to the schema. If "strict"
178 * is "true", then the database additionally is not allowed to contain extra
179 * point attributes or metadata entries that are not listed in the schema.
180 *
181 * If the database does not correspond to the schema, an exception
182 * is thrown and the reason can be found in the exception details.
183 *

185 *
186 * {
187 * "extension": "rdbx",
188 * "attributes": [
189 * "riegl.xyz*",
190 * "riegl.timestamp",
