Syntactic quality measures how far data follow the syntax laid down for them, that is, the rules set by their metadata (a data set that matches its implementation schema; a sentence that follows the grammar and vocabulary of its language). A syntactic verification meets this part, and syntactic quality can be measured, only when all of the following exist: the full set of syntactic quality rules (Annex B); a formal statement of the way the information is represented; for every rule, how compliance is to be measured, what problems will show up in the data set when the rule is broken, and what breaking it means (a broken entity integrity rule can produce duplicates); a list of any rules that are defined but not checked; how departures from the rules are recorded and reported; how many checks were run for each rule; and how many occurrences passed each rule.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
